Alright so far i got the greddy 18g kit.

Changed out the rc 440cc injectors it came with for the DW600cc ones and change the emanage to utec.

i got a meth kit and jwt clutch flywheel combo and fuel return system

NOW for my question! lol

i have Fast Intentions resonated test pipes with..... the nismo exhaust lol!

sounds great and couldnt complain.. but was wondering if i should upgrade or not?

the guys down at fast intentions said they could fab me up a true duel exhaust but was wondering if should spend the extra $1400???

or if my nismo exhaust with my supporting mods would get me to 420whp?

 

Its not that best designed for FI, but should be fine. Its still 3" piping dual muffler(if I recall correctly), save that money for build block in future. I read a lot of good reviews about FI but honestly I wouldn't spend that much amount on exhaust system. That's just me.

 

the nismo exhaust is really meant for NA.. I still used it on my vortech setup though and made decent power ( see sig ).. I dont know how it will perform with a turbo setup.. even though I have seen people use the nismo with a single/twin turbo setup.

and there are better exhausts or even find a used one on here for much cheaper than 1400.

 

I personally think the nismo exhaust is going to cause a restriction and not flow as well.... Although if ur only looking for 420whp you might be able to pull it off..

 

Might be able to pull it off but do the true dual anyways! You'll be a lot cooler on the street for sure. Respect level will go up at least 50 points and I will personally shake your hand when I see you at a meet.
