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.

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

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