ZZP Impala Catback Exhaust

Unlike mild steel systems like the Pacesetter, which has an expected life of 2 years in northern states, this exhaust system has been built constructed of stainless tubing and flanges. The ZZPerformance exhaust system will last virtually forever. With ZZP's exclusive whisper resonator and 3 chamber straight through mufflers, it's quiet and high flowing.

This will also fit 1997-2003 Pontiac Grand Prix's with the 3.8L engine. Works on all 3.8L engines-Both Supercharged and naturally aspirated.

All stainless system fully tig welded. Easy clamp in and bolt on installation with all required hangers. No welding needed. The 2 1/2" version bolts right up to your stock downpipe flange or standard aftermarket downpipes with 2.5" exit flange. The 3" version will require a downpipe with a 3" exit flange.

Very best system on the market for Grand Prix', Impalas, and Monte Carlo. Cheaper than the Magnaflow and higher quality. Magnaflow systems are mig welded and do not have chambered mufflers or resonator which means they are too loud. Engineering this part was years of research and evaluation to come up with the ultimate exhaust at a reasonable price. We are the leader in the 3800 Series II and Series III market and have the very best products period.

Designed for the 2000-2005 Impala, but only the dual exhaust models. May fit the pre 2000, or 2006+.

2005 Impala catback

I waited quite a while for it bc of the backorder. But well worth it. I love the sound and noticable difference in acceleration if only minimal. I also picked up 2 sway bars and engine mounts. Car rides sweeeeet. This is just the beginning of a partial rebuild\upgrade for me. Customer srvice kept me informed with updates before the delivery. Great team.
