Dealer's GM Supplier screwed up, and didn't order the dual wall angled tips I wanted, so the dealer instead, had the the single wall tips mounted and ordered me the correct pair. When they arrive tomarrow, I will pick them up and he said I could keep the single wall tips for free.

Re: GM Performance Exhaust System
does it stick out enough to change the departure angle?

Corsa manufactures these actually... Jim Browning (the owner of Corsa) is a great guy too. They make some really nice products. I've had them on my Z06, and they rock.  |

H3 Tiger - thanks for the info. I already have the Corsa Performance Exhaust (same one sold on this website) on my H3 and so far so good after 1 year. |

Re: GM Performance Exhaust System
So what performance do such systems add?  |

Re: GM Performance Exhaust System
Very little added, probably 10hp or so. Looks cool with the dual outlets (stainless tips bling). Tips could drag on departure in heavy wheeling, but you could have a muffler shop mod tips to make them removable. Corsa sounds good, kinda of like BMW straight six.

Re: GM Performance Exhaust System

I have never really noticed a performance change after upgrading the exhaust on any of my previouse cars. However, I really noticed an increase in power at take-off and on the highway on the H3. I was very surprised and a I recommend the upgrade! Sadly that is gone now due to 35's, I felt a big change after going bigger. I am wondering if I have the dreaded head problem, becuase it was a bigger change than I expected.
