    exhaust systems for 2006 STS V6 base

    for a while now i've been searching for an exhaust system (cat-back exhaust) for my 06 STS but every single one i've looked up states its for the V8/V-series models. i've searched for the Corsa cat-back exhaust system (my first choice), Borla cat-back exhaust, Gibson exhaust system but non of them are compatible with the 3.6L engine (so the sales associates tell me). are there any mods to get these exhausts to work on the base models?

    or are there other exhaust systems that will work with the car?

    I seem to recall a member fitting a Magnaflow to a V6 STS.

    Corsa is the only one which will bolt on since its an axle back for 05-07 models.

    Gibson is made for the STSv and STS 08+ which the bumper hangs lower on. Won't look right.

    Borla is v8 specific.

    Gm made a performance exhaust for all models but is 1600

    For the corsa, so the standard v8 exhaust will work for the v6? The ease of installation is the reason i wanted a corsa in the first place

    I believe all you have to do is have it welded rather than clamped because the v6 pipe isn't quite as wide not 100%. If your close to pa welcome to stop over and check my corsa out.

    If the clamps are the only issue ill deaL with then that's not a factor. I saw one on ebay for $987 (14157), ill get it and let my mechanic do the job (hopefully it does not affect my warranty)

    Isn't welding stainless steel a bit tricky?

    My corsa and volant hasn't voided mine. My dealer is pretty cool though.

    Welding ss just requires skill and a good weld wire.

    Love it. Not a single regret other than I never hear it at its best.
