thanks, do you think the exmag would be ideal for an sr20det ?

MOST DEFINATELY!

people always say oh 80mm 80mm but please. for the average joe who has relatively stock power, a 70mm is just as good

and the ExMags are CLEAN simple and quiet!

back in the early/mid 90s, everything was near 70mm.

nowadays people enjoy being loud and obnoxious.

i personally find no problem w/ 70mm


but someone w/ a SR will say. but of course, they better back it up w/ proof and dynos :)

I notice the model pics have no resonator for exmagII. Do they come with one?? If not, it might be a lil loud huh?

mm dont know about the new ones.
my old one does.
even if there isnt one, that caniser (muffler part) isp retty big and so i think it would stll be quiet


i wll never sell mine. its low and deep but not loud and obnoxious. i like it A LOT

Having had both 80mm and 70mm exhaust on a SR, I will tell you what I think.

I had a 80mm Tanabe exhaust. Nice exhaust except the resonator cracked at the weld. I replaced it with a 70mm Border III 5Zigen exhaust. WHat I noticed right away was that the car seemed torquier but ran out of breath sooner. I also noticed that with the 5Zigen, my max boost level on my blitz meter was a tick ubder .5 bar while with the tanabe, it was firmly on the .5 mark.

Like Aaron said, 70mm is fine for stock or near stock boost (maybe up to 10 psi or so IMO). It adds to performance w/o sacrificing flow velocity too much which maintains a fatter torque curve. If you are serious about making hp, however and want to push a lot of air, then you should upgrade to 80mm.

Plus, my 5Zigen is much quieter.
