DIY Exhaust Mod – Gain of 10+ HP!!!

[TypeA]

Did this mod today. My 02 exhaust tip is welded but with a $13 1/2" bit from Home Depot I managed. I like the effect but too much of a coward to go bigger than 1/2" without a reserve muffer on hand. I am sensitive to drone and so far so good but I do wish it was a bit louder.

Just wondering now that some time has passed, is everyone still happy with their choice of drilling out? Some other sites were saying it made the boxster sound more like a japanese car which is fine if that is what you want.

Thanks,

David

Yep, still happy with 3/8" holes. It doesn't change the sound a lot -- it just adds rumble, mainly. It's not going to wake up your neighbors or turn heads when you leave cars & coffee. It's a subtle change, but worth making.

Do what everybody else told me I couldn't do cause it wouldn't fit....I installed headers and intermediate pipes from a 06 Cayman and the mufflers already had the secondary cats deleted. My Midas dealer cut and rotated the pipes a little for clearance with no issues. I vinyl ty rapped the wheel sensor wiring to the struts far from the exhaust..wa la! Still there. Sounds great and a steal for a $1000. Sounds way better than Fabspeed. I heard one and thought it sounds the ****************s!
