i just wanna get your guys output if this is bottlenecking before i decide to put my setup on.

*this is in order (car is 96 civic hb w/ b18c1)

2.5 collector header/2.5 high flow cat(yonaka/vibrant)/2.5 piping/2.25 resonator/2.78 exhaust tip.


is this fine? or should i just get a 2.5 resonator as well?

 

Dubious this would be a problem.

 

Is there a reason you don't want a 2.5" resonator?

 

how so?

no not really, just the 2.25 resonator is already on the car, but if it would be better to run a 2.5 resonator than so be it. that's all im asking for would the 2.5 resonator make a significant difference in sound? because this is my dd, and i'm sure 2.25-2.5 resonator shouldn't make a big difference since everything else isn't bottle necking correct?
