DIY Exhaust Mod – Gain of 10+ HP!!!

[crios]

Mike,
I promise not to rev it by your house...lol

It's not that loud, it's 1/2 in hole on each side, perhaps an 1 inch whole would be better, but what if then there is drone in the cabin at crusing speeds, which I've heard first hand and hated.

As for the RPM ranged...you saw the distance I drove to and back, but I would guess between 3-5K. Standing still ones probably went as high as 7K.

This is meant to be a inexpensive hack, I'm not about to fork out $$ for a dyno to prove skeptics. If you are skeptic, don't do it. I'm not selling anyone anything, I have no agenda, other than having fun with my Boxster and sharing the experience with others.

Thanks,
Cesar

Butt dyno doesn't count, BTW.
