i bought a 2.25 inch catback off of ebay for my civic coupe gsr. couple questions, since the catback is 2.25 inches and the itr axleback is 2.25 inches (correct me if im wrong) there wont be any back pressure right? also i know the fart can will have better flow because of the size, but im gettin tired of the whole look and want something cleaner; will the oem muffler cause too much backpressure or will it be fine. i was just curious because bosal is sellin an itr axleback for 115 and i was thinkin about pickin it up

also will it bolt right up or will i have to have a muffler shop hack it up i.e. add hangers or cut anything off. the car is an eg civic coupe

Unless you're turbocharged, I highly doubt a stock ITR muffler will create "too much" back pressure.

Ok yeah that's what I was thinkin. But do u know if I have to modify anything in order to make it fit or will it just bolt right up?

you might have to modify it, but you'll never know for sure since you are putting that muffler on to a different cat back. even if it is off, just go to a muffler shop and have them weld it on right.
