Getting a Custom 3.5" dump pipe and a 3" Magnaflow Highflow Cat all for AU$500, leaving the stock exhausts for now but including them dual 2.5" or 3" AU$1300 for the lot. Which I may think about in the future just need some other things fixed up first.

How do do those prices sound?

 

ok got it back and it runs alot smoother now but I think its hitting the fuel cut off now?

the exhaust guy did mention it may run about 1psi more boost, would this be enough to hit the fuel cut off?

When reving around 4-5k it kind of feels like when you hit the speed limiter on a jspec rx7 is this what the fuel cut would feel like? or is it something else?

 

on an 86-88 it would probably raise it more then 1 psi.

you definatly need to get an aftermarket boost gauge ASAP.

then a bigger fuel pump and FCD

 

Sorry I'm a newbie too all this but will this cause any lasting problems if I leave it too long? money is an issue atm thats all.......
