GM Performance Exhaust System

Just got it installed yesterday. Cat-back, single pipe, with a smaller muffler.
The dual tail pipes look great under the bumper. The sound isn't a real big change but the dual tail pipes really look awsome on the back.

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.

Interesting, I wonder what company makes this system for GM...

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.

So what performance do such systems add?

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.

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.

Even with my 35's, I still have more power than before the dual exhaust, but then I have that other thing too

You may want to have them look at the heads, because I still have pretty much as much power with the 35's as I had with the 33 Toyo's.

I installed the new, Dual Wall Tips this evening.
Wow, what a difference in look. The single wall tips just don't look as nice.

As for power? Hell I don't know. If there is a differnce in HP, I can't feel it.
But the dual tail pipes in stainless really do look nice.

I think that the departure angle will be shortened a bit, but since I haven't really done serious off roading, it doesn't mean much to me.
If I need to, I can always remove the tips. The pipes hang pretty close to where the original was, and the performance muffler is smaller.

I'll post some pics up in a day or two.

Cool. Yours (GM Performance version) already has the removable tips.
