Exhaust systems

[enforcer GT]

I have a 2000 GP GT and i was looking at exhaust systems. I pretty much have it narrowed down to 2.

-SLP Powerflo
-GMPP exhaust

I know the SLP is about $550, does anyone know where and how much i can a GMPP ehxaust for?
Which one will give me more power and better sound
I would rather have an exhaust made by GM but im going to go with the one that gives me more power. Thanks. Happy Holidays.

Dont waste your money on those catback systems.... Just get the mufflers that those systems use and leave it at that. You wont see a gain worth the money w/ those catbacks.


Catbacks are for sound only.

I agree, maybe a hi flow cat would not hurt, you will hear a better sound thats about it from that.
