hey there guys... i own a 2006 gmc sierra 2500hd 6.0L crew cab, currently with cams and headers anyways.. i want a catback exhaust system so what do u recomend in terms of performance....

1) Gibson http://www.summitracing.com/parts/GIB-5009/


2) MagnaFlow http://www.summitracing.com/parts/MPE-15789/

Regards

 

Neither, I'd recommend Corsa if you're willing to pay extra. You can't beat the sound at WOT and it is very mild at idle/easy throttle. I've had mine since 2004 and never had any structure or rust issues. Not bad considering my truck was in humid South Carolina for 4 years.

corsa is a bit expensive.. i dont wanna spend alot because im willing to install more parts, 1 of those is suitable for me..

 

Magnaflow, but what are your other mods....

 

Borla Headers, Comp 212/216 0.520/0.524, K&N air intake , TCI clutch, Hp Tuners.

 

My Gibson stainless single in/dual out has held up to the elements excellently for about 9 years through New Jersey winters, but was way too quiet for my taste until I removed the tail pipes and dumped it before the axle. Can't say that I noticed much difference in performance, but I think that there's only a little to be had in the cat backs. I've heard other Gibson systems, and they're quiet too. I've heard and driven trucks with Magnaflow systems, and they're very quiet at idle, but have a nice growl at WOT. My future set up is going to consist of 2 Magnaflow 4" round 14" long mufflers, a Magnaflow x-pipe, and will be dumped either before or after the axle, not sure yet.

I have heard that Magnaflow used to own Gibson, but I'm not sure how true that is. I'll bet that they perform about the same, so if I were to choose I'd go by sound, and I like the way the Magnaflow sounds better.

 

I had a Gibson - took it off right away and tried Gibsons race truck muffler - didnt like that either - Too quiet - both systems - mufflers - I replaced the entire thing with a Flowmaster - but I replaced the muffler with a 40 series Delta Flow - Love it - sound great ! In your situation - I would pick Magnaflow

 

magnaflow!

 

I have that Gibson exhaust in a SI/DO setup on a 5.3l with the tailpipes removed no dumps and absolutely love it... no resonation in the cab, sounds good outside, throaty from the back / up close. It really howls at WOT throttle pulls you wouldn't be disappointed.

 

+1 on the gibson, if you want a good sound at WOT and not so loud while ur DD, id rock it
