Bend, Or.
I havn't been out there yet.

I have Two trucks now.
I couldn't sell my step side so i'm keeping it as a Family airloom. Its paid off so It's all good.

I love my GMC. I wish they sold VHO's up here.
I'll find a 6.0 soon enough.

I making sure I do things right the first time around with this one. Especially the exhaust..

I like both,right now i have bullets on and a aggressive PCM because I am not towing heavy loads out of town with the bad winter roads,I will soon put the cats back on.The HD cats flow so well I doubt theres any performance gains,It has a lot more roar with the bullets,Its nice to be able to bolt them on when i feel like something different.

50 flowmaster 3" in 2x2 1/4" out exited in front of rear tire. got tired of it in a month.

switched to 3" in 3" out 40 flow dumped in front of rear axle like it alot better sound so much deeper and louder.

Ill probably end up going with a magnaflow eventually

You guys with the dual 3"in/outs dumped I guess you got rid or the factory y pipe have you lost alot of tq down low how does it sound

I had a Gibson on a 97 5.7 ECSB Z71 for a week. Loss of low end,MPG, and too loud in the cab.
An SS system on an 03 5.3 ECSB Z71 untill I traded it in. It was really nice for what it was. A little more power, a little more mpg, no noise in the cab.

A Corsa Touring now on an 05 ECSB Z71 and it will stay. I had an SS system for it get damaged in shippment or I would have never gone to the Corsa. I just could not go through all the trouble again of hunting another SS system down. The Corsa is nice. When you do hear it in the cab, it is a bit louder in the cab than a 2500 HD 4X4 Long bed with a 6.0 & OE exhaust. My hunting partner has one and I drive it all the time. I was surprised how much I could hear it the first time I drove it. It looks just like the SS muffler.

litllered 4.8

I kept factory y pipe and dumped mine. Didn't feel like I lost anything down low and after my dyno I lost no torque down low. It sounds great with the lt's and high flow cats but does get a little noise in the cab, but I like it loud
