Yea man. For it to be a three inch I've been impressed. I've hit some massiv dips and humps around campus where the construction is and no issues. best of luck!

P.S you won't regret the sound

ok call me crazy but hear me out...i've always seen people say 3" flows more than even dual 2.5" pipes (odd to me cause you'd think 2.5x2=5" which is more than 3") well 20 years later i decided to test that. i punched in 2.5" pipe at a velocity of idk 5 feet per second (sounds right maybe) and out comes whatever value you want to view. lets go with cubic/inch per second; i get 294.5. well times 2 and we get 588 cubic/inch per second.

now 3" pipe is only 424.1. so if im not wrong what people have always said is wrong. the NA Z not having a lot of power really maybe all these 2.5" dual CBE's are hurting us cause the openess is to great and the scavaging sucks. maybe this CBE does add good power because the smaller flow rate is keeping the scavaging up better.

am i crazy?

Wonder if it would be possible to just order the axle back section of the exhaust since im installing a BP Performance kit 1.5 ??

I don't know a thing about what you're talking about but by your explanation it seems possible. I'd like to learn more about the science behind all of it.

I am pretty sure if you contact soho or Sasha they can work something out.

whats up david,

the y back section will bolt straight to the BP kit. i did some research on this a while back. Just tell Sasha that its for a oem style exhaust. hes already made a kit like that!

If people like the single maybe we'll fix the hole on the other side issue with a dry carbon insert to block it so it looks like OEM is supposed to only have one muffler.

If you do the calculations on that website, then a 3' single exhaust is perfect for a bolt on Z. However, if I read everything right a 3' single exhaust would be a bottleneck for a turbo Z. Or am I missing something?
