    [Question from RENTERIA316]

    Does anyone have a dual exhaust on their Trailblazer? If so how much more HP do you get and what is a good recommendation. I will have the V8 and I just need to make sure the exhaust is not to big otherwise it will be noisy.

    I own an 04 LS TB which is a straight 6. There aren't that many exhasut systems out there that I coud find. I do know Borla makes one. Gibbson said no, that tried to make one and it sounded bad so they never put it on the market. I put a JBA exhaust system on mine. The costs was around 300.00. and I did the labor myself. I will have to say, since mine is a straight 6, uuuuugggggg....it is loud (which I did want) but I sound like a honda civic coming down the street. of course, it will sound better on a v8. I just wanted to let everyone know that if you own a 6 it does sound like a civic, it has a little more ump to it, but yeah, wasn't the best of moves.

    I couldn't even find the JBA exhaust system on their website for the Trailblazer. Do you have a link to it?

    Looks pretty sweet. The TB stock is so quiet that you can hardly even hear it running. That's fine for most. Too bad they can't get a deeper sound from it.

    Borla add-on

    I see Borla has alot of the muffler-tip combos that look like it will bolt right on the trailblazer. Because of the stock mufflers placement, i think it should be no problem. Question is, how loud is it going to be? Anyone try this yet? I'm looking for a deeper sound but not like those ultra loud rice rocket sriding around

    Yeah, that's not a sound that someone expects to get coming from a Chevy. :-/

    I've not seen anyone do that myself. Anyone?

    Thr Borla one is around 1000 dollars. I bought the JBA system. It invols sawing off the orignal pipe and then boltin on the JBA pipe. the sound, it all depends on what you have. I have a striaght 6, so mine is loud but not overwhelming, and sounds like a civic.If you don't mind it sounding like a iciv then do JBA, but it all depends on what size you.
