New Soho Single exit for the 370z!!

JC-Nismo · 02-19-2015, 11:28 AM

All the why's and how's................ Could it just be the best exhaust @ getting HP over all the others that were claimed to be the best at considerably higher prices? Just saying..............
I would assume the dual setup sounds the same, correct? Very interested in this, this sound is flipping AWESOME!!!

Numbers can vary according to a lot of variations. Once we get a stock 370Z on the dyno, we can then determine the percentage increase that has been made in power and torque overall.

Thanks for chiming in soho. Didn't know what kind of dynojet it was!

Lol that could very well be the case! I hope it is. The dual setup probably won't be as aggressive as the single IMO. Also, they haven't made their dual for this car yet so it's hard to tell haha and thank you, i agree on the sound part

Going to the dyno tomorrow to get a baseline on that dyno... Also for the guy that wanted a picture of the exhaust here is one from the rear. I had the stock muffler and mid pipe in the hatch at this time so I think it is a tad bit lower. I'm also lowered on eibach profit springs. Had the exhaust in for about 6000 miles and haven't scraped yet.

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.

NoLaKrewe · 02-21-2015, 03:06 AM

Either way I'm so appreciative of this thread. I've been so stuck on duel for so long, this single..I've been needing it. I Found THIS Hot *** Picture

synolimit · 02-21-2015, 06:53 AM

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.

Just so I'm clear, you're going to dyno a stock car, add this cbe and dyno again to see gains? While that's great we REALLY need to see stock, this cbe and a normal dual cbe so we know what dual 2.5" and single 3" do. Then the ultimate test is a tuned car with test pipes and oem cbe vs tuned, test pipes and this cbe vs a tuned, test pipe normal 2.5" dual cbe.

Scott, thank you for all the research haha I am not familiar with all of that! Also, I am about to dyno my car stock today. removing the exhaust right now! lol as for the other comparisons i will have to find someone with an exhuast to come and compare.
