exhaust diameter

[yungjay]

I have a yonaka exaust on my civic right now and the piping size is 2.5 inches which is 63.5mm and I wanted to put on a different axle back on it which is 60mm or 2.3 inches I was wondering if I could make it fit? or if I would have to just get new piping from the cat back?

The 2 bolt bracket should have no problem bolting up your new axle-back muffler. Also the reduced overall inner diameter is not enough to hinder any performance.

I have the Yonaka cat-back on my CRV. With a catalytic converter on to negate any rasp, the exhaust sounds really good.
