Gibson Cat Back

Stepside Z · June 8, 2002

I am looking for some input on Gibson Cat Back systems. What did you think? How was the performance?

Dont have any real numbers, but i do like the mellow sound.

To be honest with you, i might go with a louder muffler if i can soon.

Thanks. Do you like the quality? How well did it fit?

John, for what it's worth, my friend Dave, with the white Dodge, has a Gibson kit on it and he's real happy with it. He's limited on how long of a tip he can use though because it bends shortly after the tailpipes go back unser the bumper. He has the dual pipes routed out the back.

The sam kit for the Silverado's require removal of the spare tire on the 4x4's. ???

Gibson Exhaust Check the notes on the application guide for the different style exhaust systems.

Sometimes I think my Gibson is too quiet, too. Like last night when I hit the starter a second time at the gas station. Boy, I hate when that happens.

Did you notice any real power or mpg gain? I am looking at the single system. Which system do you have?

Hey Step,

I have an '02 Avalanche, added the Gibson Single Swept Side. I love the sound. Just perfect, not too much sound in the cab unless you get on it, real nice sound outside. The SSS is supposed to add the least sound and most horsepower, that's what I'm looking for. I put a flowmaster on a Suburban before and the in-cab noise was very unpleasant, my wife never quit complaining. She likes the sound of the Gibson.

I gained .5 mpg, I calculate every tank in my head and I went from solid 13.5 to just over 14. I drive very aggressively.

Good luck,

MB-)

Had a swept side installed on my '00 rado. Kept it installed for a couple of months while researching for a replacement. The system is quiet at idle, drove me nuts with in cab resonance at 1500-1800 rpms, and suffered loss of low end torque. Bottom line...I hated it. I'm glad I replaced it as the new systems provides what the gibson didn't.

The Gibson sideswept single catback and UPD added about 10% to my MPG. I'm now averaging 20 MPG. I feel more lower to midrange punch when I hit the go pedal.

Stepside Z,

I have the dual sideswept gibson system for my HD. It sounds real good w/o being obnoxious. Install was easy; the fit is almost perfect.

Power was immediately noticeable as well.

I did not notice any mpg increase, but I do mostly city-type driving. If and when I get on the highway for any appreciable time, I'll know better what kind of mpg increase (if any) I got.

I have heard alot of good things about pvmufflers. I will have to look into those cause I want a good system that won't cause a loss in my low end torque. How is the sound on the system?

Avalancher,

What do you thing of your Flex-a-lite 282 fan? Improvements in mileage/power? Worth the money? Any grief from the dealer?

Avalancher · July 3, 2002

MarkD,

I love the fans, they were expensive though. Fit and all is great, an easy DIY mod! I can tell a BIG difference when it is hot out 85+, if you can tell when your fan clutch has tightened up on hot days, then you will feel this difference. The main cool difference I felt was throttle response.

I like it, I think it is worth the money, it's a quality product!

Dealer, probably won't like it. It hasn't been back to them for some time.
