hello all, im new to the forums and im coming from a 2005 pontiac gto. i got the titan last week and already put exhaust on it. ive done some searching because i didnt want to get flamed before i asked these questions but i couldnt find anything incredibly clear. basically i am looking to know if i did the right thing in general with my exhaust setup. i know peoples opinions will differ. i kept the y pipe configuration but made it 2.5 inch piping going into a single inlet muffler wiith a single outlet with 3 inch piping after the muffler. does this sound like an ok setup? pros cons?
