New Soho Single exit for the 370z!!

Gregor12

hey scott, let me clear things up haha i know this thread has turned into a cluster ****
First mod i purchased from soho motosports a while back was their rear section of the catback exhaust which uses the factory y-pipe. The first pull we did when it had no tune (factory) was in 4th gear (just to do a small pull then tighten down the straps again before fifth)

-it made 299.45rwhp and 24X lbft in 4th gear

Last week, I bought and installed their y-pipe replacing the factory POS y-pipe. strapped it down and did a 4th gear pull to compare to my last 4th gear pull. (this was a stock tune comparison)

- with y-pipe and y-back exhaust it made 313.4rwhp and 258.4lb/ft in 4th gear

So after that, nick did 3 5th gear pulls since 5th is 1:1. The video I posted was the last 5th gear pull we did of the day.

- with the exhaust and factory tune it made 320.46 rwhp and 269.09 lb ft (5th gear)

let me know if you have any other questions. as for the dyno being off I really don’t think so. they’ve had 3 annual dyno days there and nobody was reading high comparing to their previous dyno tunes.

ill ask nick for SAE numbers as well for a comparison. and SOMEONE FIND ME A STOCK Z lol
