I too do not think that increase hp, but I would like to improve the sound, but without impairing performance. That's why I put the photo of the exhaust cut for understanding what 'better.

keep in mind that the second pic is pretty much a copy or what Porsche does for the PSE - a system THEY developed and sell on thier cars, I am sure it is not performance limiting to a greater factor than they are willing to put up with.... which should be fairly minimal

just my thought

Even with its pse porsche opriginale put a tube of 2.25? Someone said that with this change by passing the resonance chamber 3 and 'true

I dont think you completely by-pass #3 but perhaps


I am not a airflow dynamics expert but worked with a PhD in fluid dynamics long enough to know.... I am not that either

Thanks for pointing me to this thread. Since there is so much to read, can someone please tell me what I need to do to get the best sound from the 3.6 mufflers? I'm going to start at page 1 and hope that I can get a response before I get to page 38, lol.

see post 520 (IMO after reading ALL THIS, that is what I determined the "best" for the 3.6 cans...) it sounded WONDERFUL!!!

2.25" seems to be the best size piping? Any pictures of the mufflers stock before the mod so I can compare?

I'm excited about this. Thanks guys!

post #23 = before and after pics from Tim's Honda --- err 911 I mean

orientblue3

Great, thank you! So 2.25" is the cats meow for the piping, correct? I think that's all I need now!

Did anyone take this job to a muffler shop? If so, roughly what did you pay?

ivangene

yes, muffler shops charge between $40 and $400 depending on how stupid they are!!!

I am thinking about this mod. Looked at post #520. Great pics. Thanks.

The PO of my 996 had some type of PSE installed as there is the PSE button on the dash near the nav unit. How does this button work?

Ale-Superbike

I adjusted my muffler with a 2-inch pipe, the sound at idle and 'slightly stronger but when accelerating increases without being too strong. Perfect.

I thought PSE was standard on the 40th. If the button was there, maybe he pulled it out.... just press the button (LED on) the go in quiet mode.

Bawhahaha!!!

If i want to do this mod to a 3.4 what do i tell the muffler shop? Does anyone have a sound clip? It won't sound all racer or anything will it?
