All stainless construction, including the tubing itself, flange, hangers, and band clamps. The ZZPerformance 3" exhaust system for your 2004 and newer Grand Prix will last virtually forever. Unlike mild steel systems like the Pacesetter, which has an expected life of 2 years in northern states, this exhaust system has been built with no compromises.

Stainless steel mandrel bent tubing
Custom Y transitions smoothly from 3" to dual 2.25"
Double wall polished Stainless tips
Polished ZZP mufflers
Stainless steel hangers in all OEM locations
Includes all required clamps and a gasket
Direct bolt in when used with our 3" bolt in exit downpipe

Does not fit the '05+ Grand Prix GXP, however our 2.5" catback does fit the GXP.

Overall worth it

I love the sound and performance of the exaust. Fitment seemed to bretty decent as well, for a prefab. It does hang slightly lower than stock. My only issue is where it splits over to the drivers side, it wants to sag a little bit. There no factory hunger to begin with so there is only so much that can be done.

3" Exhaust Install on 05 Grand Prix

3” exhaust installed on a 2005 Pontiac GTP Grand Prix. Modifications - Reduction pulley, PCM performance tune, front power log, throttle body spacer. Pros: - High quality exhaust. Really nice looking - Easy installation - Noticeable performance increase from factory exhaust Cons: - Mufflers sit a bit lower than factory mufflers - Excessive droning and harmonic vibrations inside the cabin, very annoyng at low RPM. I ended up shelling out another $130 for Car Chemistry Inc 3 disk CC inserts (2.25”). These go into the exhaust behind each muffler. I installed the inserts - as is- without the supplied restrictor and outlet plug caps to fix the dronning and vibration problems. Additional info for general situational awareness: - 2 exhaust hanger O rings - 4 exhaust hanger rubber isolators - O2 extension harness needed - ZZ-38MANGKT -3800 Stock Manifold Gasket (optional- check condition of your original) I replaced mine. - Exhaust hit the metal cage that goes around the gas tank. This can be remedied by bending the exhaust hanger arm or by using a slightly larger exhaust hanger rubber isolator. I used a different rubber isolatorto fix the problem. -Minimal power loss with 3 disk CC inserts.

3800 3” exhaust

This is an awesome exhaust. I bought it to go with the headers I also purchased. Easy to install. All the gaskets and really nice clamps come with it. I bought all new zzp rubber hangers to go with it.
