For those of you running straight through style mufflers on the street, do you have any resonance at cruising speeds?
If so, did you have to run a second muffler/resonator to try to get rid of the resonance or noise of the exhaust?
Is one of these mufflers per side too loud for a street car?


Note: I am planning on changing my exhaust to a straight through 2.5" system and I am considering using two straight through type mufflers in the rear. But I have read that this can be noisy for a street car and this can cause resonance due to the louder type of muffler. Some cases a second muffler/resonator might be required under the rear seat for the noise and resonance. If so, then I was looking at another straight through style muffler for this issue.

Thanks
