Gibson CAT Back

6.2 L Before removal stock CAT Back system









After modifications,

an installation,









Had to move a hanger because Gibson sent the 6.5 bed length bed as opposed to the 8 foot that I have. The part number they shipped, see below

Features for Part #619904
Bolt on a Gibson Exhaust System for intense pavement-searing power
Dyno proven to unleash huge gains in horsepower and torque
Custom designed and tuned for your year, make and model vehicle
Bolsters towing torque, off-the-line acceleration and power throughout the RPM range
Enhanced engine efficiency improves fuel economy, depending on driving style
SuperFlow straight-through mufflers flow with nearly zero backpressure
Baffled and chambered muffler design delivers a rich, throaty rumble
Mandrel bent for unrestricted exhaust flow
Finished with brilliantly polished T304 stainless steel tips
Choose from a variety of styles engineered to match your driving style
Built from your choice of heavy-duty aluminized steel or hard-wearing 409L stainless steel
Gibson's innovative "Slip Fit" connections reduce backpressure and smooth out turbulence
Comes with zinc-plated, factory-style hangers for a hassle-free, bolt-on setup
50-state street legal
Made with pride in the USA
Your Gibson Exhaust System is backed by a limited Lifetime Warranty

After install and hanger modification, amazingly better sound from the rear at idle and a kick in the pants acceleration with pedal down at 2000 RPM and 45 MPH.

Thanks for the post....

Did this system eliminate one of the resonators?

Did you happen to cut open stock mugfler?

I was wondering if it was a straight thru tuned chamber design like the 5.0

Looks like a very nice system

No I did not cut the stock open, I will say the new Gibson has a throatier sound vs the stock and there was no loss of the resonator, on my 6.2 L system I only discovered 1 resonator.

Will this void your warranty?

Other than the Sound and the name Gibson on it, what are the other benefits VS the cost?

I have the 6.5' bed but all I can find are the exhaust for the 8' bed, I guess I should call Gibson or send them an email.

Do you have any sound clips?
