Question:

What dual exhaust system is best for a 2004 3.4L Impala?

I've been looking around, and there is a dual exhaust kit offered by GM which looks nice and I can get it for about $500 with the dual exhaust conversion kit (required since my stock exhaust is single).There is also the Dynomax Performance Super Turbo 19363 that can fit, and would be about $355 with the conversion kit and after mail-in rebates. I am thinking of going with this kit, if not the GM one.I've also some people put on Flowmaster 40's, but I don't know if they come in a complete exhaust kit. I have only found mufflers of that series.Corsa offers an exhaust kit, but it is $1,100 and I am not spending that much.I also have heard of Magnaflow, but the only system they have fits the current generation of Impala's which have a different frame and body style.I am not looking too much into performance gains (just a little gain if any), and I am looking for more of a nice sounding, free flowing system. Anybody got any opinions?

Answer:

another fine example of a really crappy driver right there lol. backoff, thats why he was braking, to force you around before you ran him over.
I answered this question the last time you asked it - like HotRodGuy said - adding an exhaust does not change what your car is. There are no specific guidelines stating what qualifies your car as a High Output or High Performance V6. If you want to put a special emblem on your car than go for it, but your car isn't a high output or high performance V6 now - it's just a V6 with an exhaust.
Go with a cat-back kit, or buy a single inlet/dual outlet muffler and have a muffler shop bend up some tailpipes for it. It will have dual exhaust tips, sound better be a little more free flowing and won't cost you an arm and a leg. The 3.4L isn't a performance engine anyway, so true dual exhaust wouldn't be worth it. I bought a Cherry Bomb muffler for my truck and it only cost about $70 with shipping and a local muffler shop bent up and welded on some dual tailpipes for about $250, so all together it only cost me $320 for a nice sounding cat-back exhaust, and it doesn't look like the cookie-cutter exhaust kits you can buy from Jegs and Summit.
