Those that have installed this system, just have a few questions:

1) Could you notice an increase in hp and overall peformance?
2) How is the sound compared to stock?
3) Anyone go back to stock step-up?
4) Is this a bolt on system and a "do-it-yourself" job?
5) Any problems with this system?

Thanks...looking to do an exhuast upgrade and just want to know is thei one worth the money.

Thanks.

1. It is louder but with a nice tone to it.
2. I do feel more power with the exhaust, but I would do the intake at the same time.
3. I wont go back to stock setup anytime soon.
4. Its a bolt on system but I would get someone to do it unless you have a lift and are a very handy person unlike myself.
5. Have had it on for about a year now and no problems so far.

Thanks for the reply.

I have done the CAI but will probably not do plenum. Hope the exhaust + CAI will make a difference.

It will.

:BIG:

I had the plenum and intake installed by themselves. I noticed a very nice bump in hp from them alone (along with a nicer sound). Then I had the ZTube and exhaust done together and did not notice as big an increase in hp as the first mods. But a way nicer sound. Louder, yes, but not outrageous. Gave a friend a ride after the exhaust (he had been in the FX before) and at close to 6000, he said (and I quote) It sounds like a Formula One, man!

Didn't do any of the installs myself. I have a very mod-friendly dealer.
