Default ~20 hp and tq from a cat back!?

https://my350z.com/forum/showthread....16#post4363516

big numbers for a cat back single. Kind of hard to believe, not calling bs, but I want to see some more exhaust dyno's for 07's.

Last 07 dyno I saw was a greddy evo TT. Made about the same power, exept it had built in test pipes. We need more dyno's.

do you think so, the greddy TT is a 3 inch dual, with or without test pipes it might loss more torque than it gains hp

YOu do realize the car is an 07, and the baseline was pretty darn good to begin with. The car made what it made, we posted the DD numbers and the DJ numbers..No trickery here. That particular exhause never was a big seller, but makes some sick power and sounds sick.

Not saying there's any trickery, thats just alot of power for cat back. I'm getting ready to pick up an 07, thats why I was interested. With the greddy, it's peak hp is what is was comparing, realizing it's not optimum for NA, even though I don't think it lost TQ, it was on an 07. I need to find some clips, if not too loud I may have to pick one up.

this was Forged's dyno with the TT and test pipes, lost maybe a little under the curve, but gained 10 peak with just exhaust, another 8 with tp's

you guys with the exhaust post some clips!!

how do they sound compared to nismo or something like the injen track or another dual with x or u piping?

im not really concerned with loudness as I am with the rasp or bees in a can sound of the hondas and various four bangers I hear at the track. How does it sound in that respect.

sorry to bring an old thread back. The link in the first post doesnt work anymore. So the turboXS catback exhaust is what made 20HP right? With nothing else? I'm looking to switch out my nismo to a more *performance* oriented exhaust.

^^ Do you speak Engrish ....and whats up with those dynos, the first one shows the car reved up to 9,500rpms?? Your base run was just screwed up, and the run with the Tanabe Touring exhaust seems fine, but you lost 10whp...

<before> bone stock


<after> tanabe touring medalion exhaust


I believe Dyno Dynamics is by far the most accurate & reliable dyno. but -_-

if you look closer, Run #6 was 250 and run 7 was 260 you MADE 10whp..Providing the number 7 comes after 6..
