Performance Exhaust and Header for Boxster

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...

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

[Darin]

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!

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?

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 !

Looking at eBay, it appears he does now:

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?

[RandallNeighbour]

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.

[Darin]

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!

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 !

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
