I am doing 2.5 inch B-piping for a nitrous maxima. How much horsepower will be lost via the resonator?

 

You are not going to lose/gain any hp whether you have a resonator or not in the B pipe. It will simply change the sound of the exhaust.

 

How will both setups below sound compared to each other?? For example..

Budget Y ---> stock cat ---> unresonated b-pipe ---> stock muffler

as to..........

Budget Y ---> stock cat ---> resonated b-pipe ---> stock muffler

 

It'll prolly sound pretty crappy either way... but less refined without the resonator. The resonator quiets it down a bit and smooths out the noise.

 

looksl iek im getting a resonator, i have a aftermarket cat and muffler already

 

Wouldn't worry too much about losing HP from a ersonator...but I WOULD worry about the car being INSANELY loud without it. I haven't done my y-pipe yet and have an 18" glasspack resonator and the car can be a bit loud at low RPM.

 

I honestly couldnt tell you, I got my stillen muffler as the 1st exhaust upgrade, and then the y pipe and then the res. b pipe. All with the stock cat. Not sure about w/ the stock b pipe, but it'll be a little more raspy w/o the resonator in the b pipe.

 

would i hear a difference if i jus get a budget y pipe nd use the stock muffler?

 

i got it with a small resonator and it sounds slightly more raspy

 

Get the resonator, I went without the first time on my 97 and it is a raspy sort of sound which goes away with the addition of the resonator.

As was mentioned earlier, no loss in the resonator its straight through.

 

yea, had the exahsut done for 135 with a resonator and 2.5 inch bent piping, non-mandrel, but tis still smooth
