Mustang dynos typically report lower numbers than, say, a dynojet.

racer_troy, do you have the full HP and torque vs rpm graphs?

Gary,

I wish I did as I was very very curious about the change in power curve.

This is all I was given.

Hi y'all! I'm about to purchase an exhaust from Che and would like to know if anyone here (from San Jose, CA.) knows or would recommend a shop that would install the exhaust i'm getting from Che... :cheers:

I made a decision to get the exhaust to Che after spending a good an hour and a half reading the thread :dance:

I just wanted to let everyone know that I received my exhaust from Che today. He received my payment on Monday and shipped out the next day. Very quick response. Further, Che replied to my questions very quickly and kept me informed of my order. It certainly is comforting to know there are quality people to do business with.

The exhaust came well packaged and no damage. As noted earlier, Che even marked where the holes needed to be drilled on the mounting. Hopefully this weekend I will get it installed. I plan on making some before and after sound clips to share.

Go Cards!

question about the exhaust
 

I have a general question for delubozpart:

I looked at the picture of the exhaust on eBay and to my it looks, well let's say "very similar" to a GHL (which I have on my Boxster), with a few significant differences:

The differences I notice are:
* The GHL uses the original mounting bracket for the stock exhaust (the one which goes on top of the exhaust). The advantage of that is that the two mounts on top of the exhaust are rubber mounted while your exhaust bolts on directly, so I'd expect that vibrations are not dampened.
* the stock exhaust (Boxster S) is mounted at 6 different locations: the mounting bracket (on top), two mounting brackets to the cats, a center mount (don't remember where it's connected - differential?) and of course the two connection tubes to the cats. The GHL uses all these mount points with exception of the center mount, but well you still have 5 mount points
* Your exhaust only seems to be mounted "on top" and then bolted on to the cats via the connection tubes. meaning 3 mount points.

This would make me a bit worried that the whole construction is not sturdy enough and will suffer metal fatigue much sooner than the GHL or the stock exhaust.

Am I missing something here?

Chris

wow :eek:

Hi Chris,

The Exhaust I'm selling are designed with 3 mounting point, with this design will cover all the Boxster model & years.

If this exhaust were made with stock Mounting location like GHL, than the R&D cost will end up higher. Which I would have to make this exhaust in 2 different applications.

With the 3 mounting location is sturdy, as the center top rubber mount absorbs the vibrations from driving which eliminate the metal fatique or stress on the welding or piping.

Please keep in mind I do offer 3 years unlimited miles warranty on these Exhausts & Headers, if any had metal or cracked flange or welding are entitle for new replacement.

Hope I answer your questions. Thank you !

:cheers:

jeff...thanks for looking out, I do have MY 99 :cheers:

Looking at eBay, it appears he does now:

:eek: :eek: :eek: :D
is that a Boxster S and is that your car and what type of exhaust you put in there :confused: :dance:

I wish it was mine but no... i found it on YouTube... It doesnt really have exhaust at all, just straight pipes, illegal, but it sounds cool as hell.

Any update/reviews from any members who have installed Che's header or exhaust?

My setup still sounds great! I think I like Che as much as his products. He's really responsive and has nearly instantly answered all my questions.

I have my exhaust from Che installed on my 97. What a difference! I could not be happier. It was more of a pain to remove the original muffler than installing the new one.

I have sound clips before and after. Please contact me if you would like me to email or if you can post them for me I would appreciate it.

Thanks to all for their input. It made the decision much easier.

Thank you Che for the outstanding service!

Darin

Hi Darin,

You are welcome, I'm Glad you are Happy with the Exhaust & its been a Pleasure. Enjoy the Exhaust ~

Che

Did the dimensions of the tubes stay the same? Can you make the pipes to a full 2 1/2"

Hello JP-s-in st.louis,

The Inlet Diameter of the Piping is 2" I had capability to make these in 2 1/2" but that will to too much unless you had Supercharger or Turbo set up for your Boxster. Also with 2 1/2" will required welding to install the exhaust. Thank you !

Che

Muffler placed on a 2002 boxster S
 

Well I got the muffler from Che last week and it is very nice. Looks shaorp and good quality. I had to take my rear bumper, spolier off to get to the top bolts of the original muffler. There is no way arround that. The muffler sounds great. It sounds just like a ferrari just a 1/2 octive lower. Butt dyno says that it is a little bit quicker.
Please email me directly if you have any installation questions.
Headers are next, curretly he does not have a header with two O2 sensor plugs. I hope that soon he will.
James

Hey Deluboz,

by chance do you know if this exhaust will be legal in canada. will i pass all emission's test's.

where do i get the muffler ? please give me a website and also the type of muffler you got it sounds great

where to get it?
 

I ordered it directly from Che, however you can find it on ebay.
I do not suggest paying extra for the titanium tips. I did and you cant even see them anyway. The tips are really tucked under the bumper.

message me if you need help installing it. It took me 2 hours, no big deal.

Stock vs. After market muffler weight wise.
 

Does anybuddy have the savings in weight over the stock muffler from any of the various aftermarket offerings?

Allen NY

after reading through this thread and looking at the auctions is there any reason to get the Catback Exhaust System when it costs $700 and only provides 5 rwhp more than the headers alone?

the headers sound like a much better deal, 10 rwhp and 17.94 torque for $500.

catback exhaust:

headers:
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=300055722972

don't get me wrong i'm sure the exhaust sounds great, but $700 for 5 rwhp... $140 per hp just seems high.

well, it depends on how you look at it. do you buy it for the power? most aftermarket boxster mufflers LOSE power anyway. most buy it for the SOUND. it's the difference between sounding like a sewing machine driving by or a PORSCHE driving by. that, and $700 is cheap compared to the competition.

Yes. Adding an aftermarket muffler to a Boxter is ALWAYS about sound. Side benefits not often considered are lighter weight in the tail of the car and less residual heat. Performance with the stock rig is already excellent. So if you like it to sound a little rough... go for it. Personally I kinda like that sewing machine sound. ;)

Exhaust installed YEAH!!!
 

Wow, what a nice difference in sound, not too loud but very nice roar. Got a professional muffler shop to do the install with me supervising every step. Final cost for install $80! Up next are the headers and Evo intake and some new performance spark plugs.

I would have to say that Che's product are very nicely made and quality is super. Wont hesitate to buy from him at ALL! Very satisfied

Darin emailed me his before and after sound clips...Here they are:

Holy Crap! 10,500 views on this thread. Che, you opened up one big can of worms, dude!

Just today I took the car out and ran it through the gears nice and hard and enjoyed that exhaust note all over again.

Does anyone who has Che's exhaust have pics of it on the car? Thanks

well, not legal in someplaces... :dance:

Hello Randall,

I sure did open up Huge can of worms :dance: , but currently I'm working on a New Project its Front Adjustable Tension Rods,Rear Adjustable Track Arms,Rear Adjustable Links. These Suspension Upgrades should be ready around Spring time :D , BTW I can e-mail the Proto sample pictures to you but I lost your e-mail. Let me know, Thank you !

BTW I will attending Tokyo Auto Salon Show from 1-10-07 till 1-18-07 Hope I can find more new Ideas and interesting products.

:cheers:

Che

Hi rule1,

Installed Pictures attached. Thank you !

Che

Not sure if anyone's asked this yet, but what about the resonance while cruising? I can't tolerate it. I want a better-sounding exhaust with no resonance that costs less than a PSE.

I have a 2000 Boxster S. Looking at the headers online it shows a place for a 02 sensor. Isn't there another one that needs to be hooked up?
It looks like these headers will eliminate the first set of cats on the 3.2 boxster. Is that correct?

Tommy

Hi Tommy,

For 2000' Boxster S you will need to add additional 2 O2 sensor bungs or bypass the 2 O2 sensors, this Header does not eliminate the first set cat. Thank you !

Che

The straight pipes
 

The Youtube video posted on this thread is of my car.

I had the straight pipes installed over a year ago and kept them for about a year . My car is a daily driver with over 140,000 miles at this point. The set up was great unless I was on the highway and trying to have a conversation on the cell phone. I now have another modified setup, it is posted on youtube also.

I have more info and pictures I can direct everyone too if there is any intrest in this set up.


Gary

Gary, please post those links because they didn't show up in your post! I'd like to see them.

Never mind. I found it on the previous page. :cheers:

Man that's loud. I can't imagine having a car any louder than mine with Che's headers and exhaust on it.

Hey all! I just recently purchased a cat-back system from Che also....and I can tell you like others have said, the quality is very good indeed. My son (who also owns a Boxster) was a welder for a few years, and he took a look at it and noted how the welds were done very nice.
As far as the sound goes, my Boxster S was pretty quiet for some reason, so the exhaust system helped a lot on my car. I could go for it to be a little louder myself, but I think most will be very happy with the deeper sound. I do get a little resonance at about 2,500 RPM, but to me that's when it sounds the best!
As far as modding the car, I'm a big fan of not having a "stock" anything, I don't think I have ever kept a car stock and probably never will.....doing stuff to my car is what I live for.
I don't think just the exhaust alone makes a big performance gain, but coupled with an EVO intake and chip, I do believe HP is gained.
