Ke55pig Posted January 7, 2016 Share Posted January 7, 2016 So my guess is its probaly in the centre resonator bit or it doesnt actually go gay at all and my cooler is restriction Link to comment https://www.sau.com.au/forums/topic/462059-3-or-35-exhaust/page/2/#findComment-7663725 Share on other sites More sharing options...
Ben C34 Posted January 7, 2016 Share Posted January 7, 2016 Stop guessing. Buy an inspection camera on ebay for 15 bucks and have a look. Link to comment https://www.sau.com.au/forums/topic/462059-3-or-35-exhaust/page/2/#findComment-7663735 Share on other sites More sharing options...
Rbdirty30 Posted January 8, 2016 Share Posted January 8, 2016 This is my exforce exhaust for my 32, it's 3.5 inch except for the rear muffler witch starts off at 3inch from the flange.

R31Nismoid Posted January 8, 2016 Share Posted January 8, 2016 So my guess is its probaly in the centre resonator bit or it doesnt actually go gay at all and my cooler is restriction Have a good look just before/after resonators/mufflers. Usually it's given away by a small reduction in the outside pipe diameter, it drops down just a bit. Not always the case but the vast majority of (quiet) Jap exhausts I've seen have it done this way if you cannot see the obvious one from the rear end. Pretty easy to confirm restriction on dyno anyway, just drop the exhaust post-dump, see what happens Link to comment https://www.sau.com.au/forums/topic/462059-3-or-35-exhaust/page/2/#findComment-7664288 Share on other sites More sharing options...
Ke55pig Posted January 8, 2016 Share Posted January 8, 2016 Yea rear cannons deffiently staraight through.Theres no drop in the pipe size but could still have some thing in the centre res.Im just going to leave it and find a 3.5-4" exhaust for it for events and put the blitz back on for the st. Tune with track exhaust and let it be restricted on the st Link to comment https://www.sau.com.au/forums/topic/462059-3-or-35-exhaust/page/2/#findComment-7664297 Share on other sites More sharing options...
Nick_GTR Posted January 9, 2016 Share Posted January 9, 2016 I wish this had been discussed a couple of months ago. I recently bought a Kakimoto Hyper Full Mega N1, supposedly 90mm throughout. Upon inspection when it arrived, it was stepped down going into the centre muffler, yet maintained the 90mm external dimensions. Fitted the exhaust anyway and even without dyno results, I can tell you that performance has been choked up. The turbos aren't spooling as quickly and I'm not nearly making as much power. Very disappointing Link to comment https://www.sau.com.au/forums/topic/462059-3-or-35-exhaust/page/2/#findComment-7664370 Share on other sites More sharing options...
Ke55pig Posted January 9, 2016 Share Posted January 9, 2016 (edited) It is verry dissapointing a big well made jap exhaust has these restrictions i noticed mine with the fact i made 350 on 98 changed to e85 and changed exhaust and still made 350 up top Dyno shows this fingers crossed it was the change of exhaust that caused it Edited January 9, 2016 by Ke55pig Link to comment https://www.sau.com.au/forums/topic/462059-3-or-35-exhaust/page/2/#findComment-7664387 Share on other sites More sharing options...
