i am moments away from spending about $3000 (even more after labor costs for install) on an Injen SES exhaust, Crawford headers, Crawford cast plenum, and Crawford cats. My question is, what should i expect to gain from these mods, rwhp-wise??

i mean, if its gonna give me a significant boost, then ill order and have them installed all at once, but if the boost is miniscule, then maybe ill just purchase the parts one by one.

...also, what do you think the labor cost would be to install those 4 items?? about $1000??

thanks for the help.

 

hmmm, well i guess thats the last time i ask for info here.

ill just get it and see what happens.

thanks

 

Impatient.

3) ordered the crawford plenum and high flow cats 900 bucks
4) IM NOT gettin a after y pipe set up exhuat DONT SPEND your money on a exaust i got a electric cut out best thing you can do.

 

why don't you look online and figure it out yourself. or use the invisible SEARCH button in between "new posts" and "quick links"

 

EASY KILLER... You post back to back in less than 5 hours on a Sunday night and you get all "antsy"?

My guess is a solid 40 rwhp, maybe a few ticks more. Don't forget to add in the z-tube for another $75-$80 and you might just hit an increase of ~45rwhp.

Before and after dynos would be great so that you could post your results. Have you considered doing the dynos?

I have the Crawford plenum and cats and have been waiting for the Crawford Headers for a while now. I also have the y-pipe portion of the exhaust and the intake. I'm hoping for ~40rwhp over stock with this setup... we'll see.

 

TECHNOSQUARE cpu im gettin that also but they said not recommended for nitrous use

 

Does anyone know if u can use the TECHNOSQUARE chip for the g35 coupe on the 2005 models? The web site lists 2003. Also does anyone have any feedback on the chip? Is it worth it?
