Ok im getting another custom exhaust made, but I just wanted to get some other opinions.

right now I have a true duel 2.5 inch cat-back with no mufflers, just resonators (lol), I was thinking of switching to a single 2.5 inch cat-back with an HKS muffler.


Which one do you guys think will make more power once I get tuned? and also Im guessing the single will be a bit quieter than the duel with the addition of a muffler lol, the one I have right now is getting a bit loud for my taste.

thanks.

(btw im running nismo headers and FI HFCs with this exhaust)

 

anyone?

 

Well going from a double 2.5" to a single 2.5" you will most likely lose power. If the sound too loud now, why don't you just add 2 mufflers to what you have with the resonators. Will quiet it down and still retain some power gain. I can't even imagine how crazy loud it must be with just two resonators and no mufflers....
