So.. After doing much research and reading a few posts on here, i decided to purchase the Yonaka Motorsports Catback exhaust for my 1997 Integra. The package arrived in about 4 days in a nice box with all the exhaust parts wrapped well and individually. The construction and welds of the exhaust are amazing. It is fully stainless and even includes hardware to install.
I just installed the exhaust a few days ago. Fitment and installation was a breeze. No Problems. No one believes i only paid $300.00 for it. The sound is very deep, and has no rasp and no drone on the highway.
Thats my 2 cents for this particular catback and i am very pleased with it.. I will do a followup review after having it on for awhile.
yeah man, they do sound good for the price.
q: are you running a high flow cat. w/ them yonakas (or a test pipe)?
if so, what are you using?
if not, were you able to honestly tell the noticeable performance difference w/o um?
yeah, one of my future plans is to bolt-up some yonakas or ws2 but i can't seem to make up my mind on converter upgrade; good ones are not that cheap at all.
test pipe is not an option for me; I can't stand the fume and I'm sorta environmentally conscious... but really the fume.

Id say i noticed an increase in power, it pulls mid range better, notice more top end. I am all stock header and cat. Helps engine breathe better, thats for sure.. but its not gonna give you huge gains
on a decently worked b18c1, my man ken got maybe a 2-3 whp gain with a hiflow cat. not what i would call OMFGZZZ. don't expect to much on a virtually stock setup. it'll be mostly noise and possibly throttle response.
