I've tried search so please don't ream me. Friend is wanting a 2.5" straight pipe from her cat on her 04 vz, I think it will have too high db limit like this, what are people's opinions?

i measured an rb26 on straight pipes and it was around the 130DB mark at 3/4's rpm, so id guess itd be around the same.

legal is 89 ish i think for your car, but im not 100% on that

might be louder then lol Rb26 has turbos to kill some of the sound

Straight 2 1/2" pipe on an alloytec? It will be loud, sound like ****, and will DEFINITELY make baby Jesus cry. And probably baby Moses too.

The word "straight" used in the above context is meaning straight pipework with no mufflers or resonators. Not straight pipe with no bends.
