i have a Eastern Perf front mount i just took off my car for sale...it has a dent in the one pipe that can be fixed and the other pipe had a line at the top like someone was gonna cut the pipe short but it does not leak and i never had a prob. the top of the back of the IC has some little dents in it to but its not the side you see..as far as perf. i went 6.7 at 104 in the 1/8 on 24psi with this IC.. i have been up to 30+ psi with no probs as the IC has no leaks. i have enclosed some pics of the IC. i could easily go have the IC fixed but i dont hvae the time. ic also comes iwth some blue silicon hoses and some good t-bolt clamps. im unloading this for $430 shipped. i also have a egt guage that shows max temp it hits it works very well cost me 200 new im unloading it for $115 shipped. i also have a 3" test pipe for $40 shipped.
