I'm looking for the specs on both GMPP exhaust.
Seems like everyone who goes with GMPP gets the sport aka perforamance. Anyone have a sound clip of both? I have heard the performance, but never seen/heard the touring. Why is the touring more expensive?

 

here ya go dude, everything you'll need.

Our admin dynoed his gm catback at 14hp

 

I checked the link and I couldnt find the differances between the two GMPP exhaust. lol so confusing, or maybe I just can't run on 2 hours of sleep. Anyways, guess I'll keep researching, I should find it sometime....*sob*

Questions about GMPP:
1. HP/TQ differances
2. Sound differances
3. Price differance and why
4. Width of the piping

 

I don't think there's a torque or horsepower diff. between the sport and touring. The touring is supposed to sound more low toned then the throaty sound of the sport. I think the touring costs more because of it less throaty tone. And I believe its 2.5 all the way through. I don't have one myself but i have done research on them. This site is your best resource to find out anything you wanna know.

 

Thanks alot. That helps alot. Both sport/performance and touring have the same 2.5 width all the way?

 

I believe so, i could be wrong, but i do believe its 2.5 all the way.

 

If that is the case, all I have to do now is compare the sounds. Anyone post a link or sound clip of the GMPP touring? I have seen/heard the sport/performance. I'm ready to order once I can hear this touring sound clip...

 

GMPP is 2.25 all the way.

 

okay, i found this out while searching for a clip for ya, ya really gotta use that search feature cuz these guys will rip you for not doing it.

That's because the 2.25" GMPP exhaust is way more free flowing than stock. There is a dyno floating around of a 12hp gain with just the GMPP cat back.

Making the exhaust 2.25" helps maintain bottom-end power. Also the fact that it's free flowing helps with the mid and top end gains. It's a great exhaust. Plus it's not raspy because of the size.

 

I found it! Here's the clip for the touring exhaust

After the GM boss at my dealership gives me the ok to install the parts myself. Thanks again...
