Do they sell this? Would be awesome if they did at a reasonable price

Maybe I missed this, you are saying 320 SAE, STD or uncorrected? Gen3's, y, and y-back right? And that video just showed it making 326 with a stillen cat back and gen3's. ******** flag. My friend with PPE long tubes, FI cat back, pulley, Z1 manifold, did 335ish uncorrected on a dyno I have done power pulls on and is spot on with PSi's dyno where I got my tune at. I hit 320 uncorrected, 317 STD, 313SAE with Gen3's, Z1tests, Tomie Y, Tomie Y-back.

numbers SAE numbers power numbers something numbers

The kit is for sale directly from SOHO Motorsports.

Japanjay,

when I dynoed my car it made 320 STD. Stock intakes (advance drop ins lol), stock cats,and stock tune. As you know, every dyno will read different. thats why I’m going to get a baseline and then exhaust run right after. I dont think this dyno is reading high. two guys i know put more power down on the dyno at z ants. Also, dans single turbo 370z came to that dyno day and put down exact numbers with motion lab tuning in charlotte.

right now were just comparing apples to apples. the only way to solve this is to do a baseline and then bolt up the exhaust and do it again. i will post it all on video for you guys to see as usual.

That middle one is not normal. The other three are and yours are not normal numbers. This platform has been around for 5 years and no one has been able to create "41whp" from just an exhaust, no tune or nothing else. Tomie's is identical, doesn't do that not even close, so I do believe you are the only one thinking that this is even possible without having a severely inflated dyno. But everyone will see when you baseline, with the exhaust put back to stock. Non-nismo will be around 273-77ish consistently state to state dyno to dyno for the last 6 years.

While I agree some numbers may seem inflated, I do think we will get to the bottom of this. Gregor seems to be doing a honest job on his end to provide us with information. Either way I did want to point out that Soho and Tomei are not the same. Sohos y pipe is 3 inch whereas tomie is only 2.5. I am not saying their is a major difference there but I do remember reading a 3 inch y pipe being recommend on the tomie thread.

I feel the need to correct you:

The Tomei Y pipe is 76.3mm, which is right around 3". Tomei Specs

I use the Motordyne Y Pipe.

I am going to have to check the Tomie thead. Could of swore they said it was 2.5. For now I stand corrected

Do you mind taking a picture from behind your car so I can see how low this exhaust hangs?

I think he meant from low...lol you can't see how low the exhaust hangs in that pic

That's all i have.

If you're going for that slammed look, it's going to scrape. i'm not very low and the rear scrapes on speed bumps sometimes.

I meant of the SoHo exhaust. I live in New Orleans, their is no way I can run the Tomei. I am hoping the Soho a little higher.

Exhaust sounds badass and the gains are incredible. Add a dummy muffler to fill the space lol.

where In the **** did I post a 41 whp gain? I never said that, I just posted numbers. THESE ARE STD NUMBERS ON A DYNOJET. They're normal. Is it higher than some other dynos? Sure why not. None of that mattes. I know who put this exhaust together. That's why I payed good money for it. It was built and designed by power junkies who get payed 6 figure salaries to build them on race cars so if it makes more than usual, I won't be surprised. Not for looks or its "shinyness". I'm not even trying to praise anyone. Im giving Yall the facts to try and help Out other 370z owners by bringing something different. I'm not here for soho Motorsports or anyone else. I represent myself and my car. I was the first one to get this exhaust so that's why I shared it on here. All of you need to be patient and just stick around. The dyno numbers will do the talking. High, low, or normal doesn't matter to me. I just want to know the Gains. I would rather not go back and fourth about it. You cannot compare dynos. It's apples to oranges.

Also, the 370z has a 18% power loss through the drivetrain if what you're saying is true. It shouldn't be that under. A 350z HR with intake and exhaust made 276 on this dyno. It's not that inflated. I've been around this dyno for 4 years now and have attended three dyno days. Go look at the videos. My brothers mustang was spot on with Paxton's dyno. Todd from Alabama brought his G and put down the exact numbers he put down at forged performance. This dyno reads a little below what used to be CINs mustang dyno. It reads higher than 42 auto sports dyno dynamics by about 15-20 percent which is normal. It reads lower than Z1's dyno. I don't know why yall like to assume I'm bullshitting. It's not going to benefit me or anyone else. There are hundreds of factors at play here as well. Different cars, temps, humidity, mods, and all kinds of **** haha. Just give me some time to get you guys a baseline so we can see the gains.

Just wait for the numbers and gains. That's all I ask lol. This should be a thread of Horsepower, torque, and other info. Not a dyno war
