Not sure, forgot to try it out at the track, I ran it with the cut out open when it still had the cat on it.. and it was about the same..

Now I dunno, its WAY loud and loses a lot down low, but pulls very well up high..

I dont really even open it, before the cat was removed it was a cheap way for my truck to be louder, then if I wanted it quit I could just close it.. now its too loud so I dont really open it.. I might get a real exhaust system someday lol

Not really, besides getting throttle happy because its REALLY responsive with no restriction its a little worse id guess, but not much

actually, with the cut out open I can run 90-100mph on the interstate and it gets AMAZING MPG.. its weird, but overall yea it probably hurts it some..

Tuned is not the word I would use to what we did, with some wisdom from jackedupcanyon we just removed T/M (which did NOTHING

) and raised my shift points.. which are too high and probably slowed it down because it revs too high sometimes and we didnt tune anything on the tranny, fuel trims or anything like that, its all 3.5 stock stuff.. and removed the speed limiter..

honestly I wish we had just left everything alone and only removed the limiter

Im trying to find an 07 3.7 PCM to put in it and start over

txcoloradoss · 11-12-2009, 08:11 PM

and why in the hell have you not fully tuned that truck man???

your lacking allot buddy

btw: when I had my cut-out on mine I would only open it up on the track when I would spray cause I hate seeing loud ass cars/trucks that run 15's or 14's lol so on spray I would run 12's haha it was all good

Colorado+SS-+12.2+pass!!

open cut out

WTRacing · 11-12-2009, 09:56 PM

Money man.. thats purely it.. It needs a tune. SO. BAD.. but its gonna be 400-500 and I just never have that.. fuckin BLOWS

Yeah, thats why I dont open it anymore really.. and another reason why I dont even have an aftermarket exhaust lol I like my truck being quiet, unless I get on it, then you just hear intake..

M_O_Z · 11-12-2009, 10:01 PM

I have no cats and mbrp and once the torque converter clutch locks up she gets pretty quite til I stomp it then it roars like a mad beast and scare ppl like crazy and I need a few more bolt ons and a tune and I am poor like you wtracing so you aren't the only one

The GM/Borla performance exhaust is so quiet and unassuming at idle, but when you step on the gas, it has a great tone to it that isn't as droney as most cat backs. J-Bo has one on his I5 and it make me jealous.

be jealous of mbrp. mine sounds amazing straight piped with the cool duals.
