I run pacesetter long tubes into a catless y pipe, then a FlowPro single in duel out to 2 2.5" duel tubes....no raspy or farting sounds, just a rumble.

 

Dual is spelled dual not duel. Sorry just bothered me

 

Maybe the left and right bank exhaust tubing duel with each other while singing blah blah blah. Did you ever think about that????

 

The two kids DUEL at the spelling bee over who will win the face off.

 

Went today and had the turn down cut off and ran the exhaust over the axle and dumped it at the muffler. Man did it help....however I will be going next week and having an 18 inch resonator/glasspac installed. I sounds so much better but still a little louder than I was wanting when I removed the cats in the first place.
