hey im new here, Names Amir and i reside in charlotte, new to the is300 world previously a hardcore supra enthusiast ahah, i have a 87 supra turbo, but i have a question, im trying to make an exhaust decision and i have selected the hks carbon ti, but i was wondering if i could run a 3inch custom exhaust on an NA 2jz, my friend greg owns a MKIV supra and he had a 3inch on it and it ran fine, and i was wondering how the 3inch would perform and would it be ok, otherwise ill get the catback hks, but i would really appreciate the help, thanks guys

i would say you would be better off with the catback.

it would be ok but i guess it depends on your definition of "ok"...

are you sure you have the 2jz N/A because I'm pretty sure the 87's came with the 7A or maybe the 1jz engine. Unless you swapped that is..

no the 87 is a 7mgte it has a 3inch exhaust on it, this exhaust is for the is, which is as you probably alreayd know, a 2jzge, so pretty much 2.75 or 3inch
