I have a whole isr exhaust setup now for g35, after i got my long tube headers installed it makes a horrible rash around 2-3k rmps either when i accelerate or let go of the gas, any ideas on how to fix this?

 

Now that you don’t have cats it’s going to rasp. Install a resonator or muffler somewhere in the new exhaust and hope for the best.

 

thanks for the reply. i have a resonated mid pipe, and the single exit exhaust has a muffler already, idk what it could be

 

And get it tuned... with long tube headers you really need it

 

I will, i’m going to get admin tuned soon, need a couple parts before i do

 

why admin?

 

he doesn’t need no knock sensor warning that’s why!

 

Gotta get them likes before your motor blows and he blocks you on insta...

 

why does everyone hate admin lol?

 

Go do some searches on the370z there's some pretty substantial threads talking about it.

 

It’s been WELL over a year, closer to 2 years since I tuned with seymore4 and I haven’t had a single issue with the car or tuning or CEL’s. And as far as customer support/response time, dude was incredible, I’d recommend him in a heartbeat regardless of location.

 

Thanks for the support! Love to hear this feedback
