Isis 4inch tip blast pipes

[Mr.Doback]

On SR, its not too bad at idle. Anything beyond its pretty loud. Wide open throttle is ridiculous and raspy with no cat or anything else. My setup is pbm cobra to test pipe to 4" blast pipes and i actually don't like the sound it makes at wot with s14 sr and working vtc, its a bit too raspy. Considering adding a muffler to clean up the sound.

Exhaust hangs low on mine, but I also have pbm subframe risers so it appears even lower between subframe, need to get hangers redone since I can't raise it anymore with hose clamps. Be ready for cops to hear you as well.
