Borla muffler

Has anyone tried this thing or know were one can find a sound clip?

I would think it will sound a bit close to V8 since it's a 6 (the front page of borla.com has 3 tunes of "sport compact", "v8 muscle", and "truck/suv" if you didn't see it). The tone of "sport compact" sounded like a broken toilet IMHO.

I don't trust Borla's claims about horsepower increases. Makes me suspicious about their other product claims.

When I used to be a Mustang guy, I know that the Borla products were viewed to be of exceptional build quality and very expensive. You really got a quality piece of metal to bolt to your car, but the general consensus was that it made the 4.6 sound like a pickup truck so no one bought it. Most of the point of the exhaust for those cars is sound unless you are going full set up with headers, mid-pipe and maybe a supercharger – then maybe you would see some power gain.

Of course the Porsche is such a different animal it might sound good on our cars, and maybe it will produce the power they say – but it didn’t do either on the Mustangs.

Borla Mufflers Are CRAP
 

Here's the dirt on the Borla Mufflers:

1) 3 piece build (2 exterior nipples, 1 interior straight tube): Over time (usually 1-2 years) the stress from hanging the mufflers will cause the nipples to crack and separate from the body of the muffler. The muffler will be covered under warranty, but you will need to fork out $$$$$ for labor to remove and replace the muffler.

2) Borla uses fiberglass filling which within the year will absorb moister, blow back to one corner of the muffler and eventually blow out. Plus the filling will soak up the moister and be very heavy which aides in cracking the nipple seams (above)

3) They are a rip-off

Magnaflow Mufflers are the BEST
 

Why?

1) Lifetime warranty

2) The best Stainless you can buy (polished mufflers) that will not rust out

3) 1-piece single manderal bent interior perforrated tube (better flow too)

4) Rockwool filling that actually expands and seals itself inside the muffler.

5) Filling expells moister

6) WAYYYY cheaper than Borla

How do I know all this???

Magnaflow National Sales Manager for 2 years.

Why do I like Magnaflow?

I've been all around the country and seen of Borla mufflers not even a year old on pallets to be sent back to Borla for warranty.

Does Magnaflow make a Boxster Muffler?
 

If so it is not on their website.

I have not heard that they do either. It would be great if they do though as I agree with KRZTACO. I bought one of their kits for the old Stang and was more than pleased. Exceptional quality product at a good price.

Boxster Muffler
 

Well, I was going to use 2 of their smaller mufflers for my ride, but I'm actually in line to have them do the job at the Tech Center, hopefully before Christmas.

Wonder why you want to change the factory dyno tuned system.

I would like a nice new exhaust primarily for a sportier sound. I'm not kidding myself into thinking that there's power to be found.

Dyno Tune
 

Actually the factory does not Dyno tune the exhaust. OEM Exhaust is used explicitly for stopping interior resonance, and sound control which results in mufflers with baffles and louvers. Flow is the last thing on thier mind. There are some exceptions (Porsche as a manufacturer is not an exception, look at all their mufflers)

I do tip my cap to Nissan for tuning for a nice sound for the 350Z and G35 coupe. Mentioning that, while at Magnaflow the 350Z and Honda S2000 were the hardest vehicles to make power from. In fact Nismo came to MF to build their system, and ANY aftermarket exhaust for the S2000 WILL loose power, no questions. The systme MF built for the S2000 that actually made power turned out to be too expensive when complete.

Changing the system
 

I want the sound of the Boxer 6 felt in my seat while carving the canyons on the weekend. Sound bouncing off the walls when I drive by as people will be in envy of the true sound of a Porche while I rip past them. With no mufflers.

The OEM size is around 1 3/4. I will be going 2 inch max for tubing and no mufflers with a balance tube uniting the two banks. It really needs an X-Pipe but we're still working on that. Should it sound like ass, I'll throw on some really small MF mufflers.

Better flow, a little more HP, but I'm after the sound. By only going up to 2 inch I will not loose any power. Should I go up to 2.25 or larger I will loose low end torque.

Well, this is kind of neat! Of all the exhaust posts on all the boards I have yet to see an "exhaust insider" speak frankly of the Boxster exhaust. Please keep us all posted as to the outcome of your system as many people would be interested. Putting together a few compoinents to make a "custom exhaust" would be great for many people. :cheers:

Hi, and Happy Thanksgiving.

I was planning on buying the Borla, but based on what I'm reading here I'm not feeling very confident in that purchase. Can anyone recommend a system that will not fall apart, degrade performance -and add sound without adding harshness?


I know that maybe asking a lot, but there must be one system out of the pack that hits the mark?


Many thanks

Wait to see the outcome of KRZTACOs' system. He seems to know what he's getting into and the results will be interesting. Better than blowing a bunch of money on a system that "claims 30+ HP just by bolting it on!". Sometimes putting together a couple of separate components works much better for sound, performance, and the wallet!

I just got my Borla for my 01 S. I bolted it on last night. I drove it around last night and today and the sound is great. Nice and deep, but not resonating and annoying. I work in the aftermarket industry and I have dealt with many different brands in the past. I am very impressed with the overall quality of the system. The install was not to complex either. The hardest part was removing the stock system. There are a few bolts at the top which are a pain to get to. Once the stock system was off, the Borla bolted in to place perfectly. The setup looks clean and simple. The system also comes with a warranty for those that care.

Happy Thanksgiving all.

I will try to take some pics and post them later.

hi, when you can please post pix, and if possible sound clips.


many thanks

I'll try to get somee from under the car next time it is on a rack.

Hi, looks pretty cool. Also, looks like it should be lighter in weight than the stock unit?

Does it change the feel of the car any?

Yea, it's much lighter than the OEM anchor. As for the feel of the car.... same. I like the fact that I can actually hear it now.

Cool :cool: The muffler looks nice.

Got a response from Borla today:

"Part#: 140115
Description: BOXSTER S 00-04 3.2L 6 CYL MT RWD 2DR D OV RL AC R
In Stock: 0
Price: $849.99

The system is out of stock and the anticipated lead-time is 3-4 weeks. As for the sound clips. Borla does not give out sound clips for several reason but I can assure you this: Borla's sound is a deep, aggressive, throaty but still very classy but not so loud sound."

I was asking them if the new sound will scare my neighbours off LOL.

Hi all,

I was hoping for an update on the Borla muffler. I'm still considering one, but I haven't read any comments on it lately. I'm particularly interested in the resonance issues.

If you got a Borla on your box, please share!!!

Hi, same here. I'd love to hear some feedback and a sound clip of the Borla system.

I'm waiting on a system I ordered from Jegs....it's expected sometime this week.

Hi,

Looks Great! Borla has a long-standing reputation for making some very good Kit! Good Luck!...

Happy Motoring!... Jim'99

I'd greatly appreciate a video, as I'm sure everyone else would! When I had my Romulus I made a video just so everyone could see. I posted it over on autobahn.

Sold that exhaust cuz I thought I was going to get rid of my S, but now I'm getting Schnell headers and either borla or Schnell exhaust. I wanna make this thing loud now.

My mechanic recently told me that he's finding some aftermarket exhaust systems (manifolds, cats and mufflers) are generating far more heat than factory pieces and melting hoses nearby.

Has anyone experienced this yet or read about it?

While I'd love to put the schnell exhaust manifolds on my car, I'd hate to start melting stuff and finding myself stuck on the side of the road unnecessarily.

Check this site out.......

Notice how he has wrapped the nearby lines with reflective heat tape.

Remember you'll be going faster so it will cool things off more hahahahaha

Might want to consider wrapping the headers just as a precaution.


Jegs/Borla update:

Borla reports that my system is built and on it's way to Jegs. I hope to have it sometime next week. If it arrives next week that would put the wait time at about a month. Not too big a deal as it's winter here in the Northeast and the car isn't used that much, if at all.

Borla customer service has been first rate....hope I don't need to find out if that stays true post sale.

Sometimes the aftermarket headers/exhaust use thinner gauge steel which causes more heat to radiate.

Hello everyone, I have the original Borla exhaust and the car in the pic is mine. They used my car in developing the exhaust. It is about 20 lbs, if I remember correctly. I have to check the papers at home. It also sounds great with the top down. I think after a while it did get louder, but not really loud. It is really cool to hear the sound of the car bounce off of the canyon walls. It was such an improvement over the stock exhaust. There is also a 3-5 hp gain and I do have the dyno sheets. Not much but at least it did not go down. Another cool thing is that when you come off a hard acceleration and let off the gas the car will burble. Also it is 2 canisters as opposed the the stock 1 canister.

The downside. It does resonate between 2.2k and 3k. If you always keep it above that it is great. I think that since I have had it awhile it has gotten a little louder but if you cruise through the neighborhood it is not loud at all.

They did give me 3 to test out and maybe on hind sight I should have picked the 2nd one. It was a little quieter, but that burble is just so cool. So is the echo off of the canyon walls. Nay this is the best one.

I have had no heat problems at all.

doclaw64 any chance you have a sound clip? I'm waiting on a Borla system I ordered about a month ago. I'm expecting it to arrive late next week. But, of course I simply can not wait to hear it :)

Please feel free to share any other thoughts on the system and Borla customer services.


many thanks

Sorry don't have a sound clip but will see if I can get one.
