DIY Exhaust Mod – Gain of 10+ HP!!!

[2000PorscheBoxster]

okay okay, i drilled THREE HOLES per side and it seems i've gotten nowhere1

as stated previosu, i have a NON-S 2000 porsche boxster

It seems i have drilled three holes per side into an isolated chamber thus producing zero net results!

Should i keep drilling and pierce the wall of this chamber and finally find a chamber that will produce some symphonic exhaust sounds?

bueller buelller bueller!

can someone chime in on this?

or a cutaway of the 2000 OEM porsche boxster non-s exhaust would be helpful too (i could determine whether to keep drilling through or not)

Hi Fella!

Sorry your having trouble doing this mod,

I have a 1999 986 with the single tail pipe like yours, I had a bit of trouble making the inital holes, but even with small diameter 10mm holes the sound was noticable louder, when looking into the end of my tail-pipe the holes are just before the bend towards the middle, not sure why you have not had any results yet.
Could you maybe post some pics that may help others to diagnose your problem

OK champ.. sorry to get here this late in the game of frustration. i have a non- S 1999. in the case of my muffler, the reason you were NOT getting a difference in sound is because the CHAMBER is already OPEN to the front and outside, right between the 2 exhausting pipes....so you are not making a difference by drilling again, UNLESS the drilling was significantly larger than suggested by CRIOS...(my new hero BTW). Don't have pics, again, at least in my case, that is what i found. the CENTER chamber is NOT sealed as in the case of the pics shown by CRIOS.
