  • Gm Performance Exhaust (beware)

    Well guys I thought it would of been a good exhaust and be hassle free with the dealer for the warranty but after installing it, I as so much disapointed that I have to worn everyone to beware of this system.
    Sound is somewhat not even apparent. I'm sure if I was to remove the resinator it would sound meen but not impress for that at all. The tips are mediocre but shorter by almost 2". Being this shorter I was affread that it might burn my valence as it is resessed inside. After spending lots of time adjusting I was still not able to get both tail tip equaly flush with valence but was still ending inside the valence. Other than that it's a 2 1/4" but the bends are long radius and fit inside each other pieces well. I had to remove my trailer hitch and then I would of had to remove so much meat on the hitch braces that I would of had to beaf it up somehow.
    It's going back to the dealer. Hoping they will take it back as it was special order from the USA. Man that sucks. Should of followed my instinct and gone with GT-R.
    Sam, I shall talk to you on Monday when I return this piece of crap.

      I'm not sure.. if she got it she had it on the GXP when she got it? I don't remember hearing about her putting it on?

      I dont recall anyone besides that questionable one getting it.. always wondered what it was like.

                      If the system's not good, we want to know. Wonder what Stacy thinks. That would actually be a worthy post from her.

                              I bought one too and if i could go back i wouldnt have bought it. Its a alright noise and all but it does not stick out the rear of the bumper and your exhaust goes behind your bumper. Was not impressed on that....thats the only downside of this product.
