The bulk of this text is taken from my review I posted directly on Enjuku’s website, however this includes pics. Enjoy!

I was looking for an S14 cat-back alternative to the outrageous prices of some of the well-known exhaust manufacturers. Asked Ken about the ISIS quality and if they've been satisfied with the products so far and was convinced to give this a try.



Exhaust arrived well-packed only with a few issues: unless they are still residing deep inside the bowls of the exhaust pipes, I didn't receive the gasket/hardware bag which may have just been a slip up; and the right 3.5" exhaust tip was slightly bent but was fixed by shaping it with a soft hammer and the included silencer to match the circular profile. Stainless looked pristine and I examined every weld for any slag or any area where the weld didn't achieve full penetration....couldn't find a single one! My dog's squirrel approves



Installation was straightforward but a bit of advice; start with the middle exhaust hanger on the rear section then move to the rearmost two near the bumper, then finish with the closest to the sway bar/diff. The middle hanger could stand to move 1 to 1.5" forward and the front hanger about 1" rearward. I moved on to the front section and bolted it to my Catco 3" cat while holding up the other end using an M10x1.50 bolt attached to the rear section. After I tightened up to the cat, I moved to the four bolts/nuts to join the front and rear sections, again using a total of four M10x1.50 bolts with a lock washer and flanged hex nuts. Because I didn't have a gasket, I used some high-temp red RTV but plan to fix this soon. Fitment to the OEM bumper is very nice and does not damage the paint. If there was an exhaust to OEM bumper thread, this would be the standard.



















Exhaust note is surprisingly quiet especially at idle on my SR20 using a Tomei Expreme and 3" back exhaust, which is nice if you daily for more than 45 minutes to work each way like me. Climb in revs and you notice no rattling/raspiness and a full sounding grunt....makes good music with the turbo spool.
