Thanks everyone!!.......You too Miller.....I guess I took what you said the wrong way. No hard feelings?
What I am hearing is that if I want to stay with GMPP I have gone as far as I can go. That's cool........a exhaust might buy me 5 hp or so but probably not worth the investment.
Will the GMPP tune be OK with the HF CAT and will it bolt up to the stock exhaust without mod?? Which one do you guys recommend? That sounds like my best option right now.......then maybe go with a Westers after that.
Sorry I haven't been back earlier...work has been a bitch!
How bout that new Vette?
