I had the same cat-back, swept-side, on my last truck and didn't have a noise problem at all. You could barely hear it. It almost sounded like the stock system until you mashed the pedal down. It was definitely better than stock and worked well with a CAI.

I put on the Sport truck exhaust when the truck had 500 miles - def not loud
- only slightly louder than stock - no interior resonance - did not do the truck justice - I contacted Gibson R&D and ordered just the RaceTruck muffler - same 3" in and 2 - 2.5" out - mine are bothout the right rear
The Race muffler is shorter - added in a 8" piece of 3" to make it fit.
Much Much better - It is loud but not terrible - some interior resonance
but not terrible - Much improved throttle repsonse - runs much better
Would do it again. Really like the sound - much like a big block muscle car sound. It does burble on decel, but doesnt pop or spit. You def know it is there - The Sport system is not much louder than stock (anyone want to buy a sport muffler ??

) - quality and workmanship is good.
