Hello everyone,
I have a 92 rhd 180sx that ill be changing out the downpipe and deleting the cat so id like some opinions on what would be a better flowing and more reliable setup between these 2.
So I have a full race bottom mount manifold, s15 turbo and a nismo 3in exhaust, currently with the oem outlet downpipe and cat.
So im looking at the parts shop max cobra downpipe vs a tomei turbo oulet to a isr downpipe and maybe welding a vibrant flex joint.
Which should flow more, better clearance, ect...
