Alright, finally this Sat. I am putting my JDM 4-1 header and test pipe on, but want to know if there is anything special in doing it? I have the gasket for the JDM header to the test pipe, so is that all I need? Just put it all on? Any suggestions??

Thanks guys!

 

You may need a three bolt gasket and bolts for the test pipe to your exhaust.... and also maybe some longer bolts for your factory springs to attach your header to cat convertor.

 

I think i gots all that stuff

Hey Mark, who is a good dyno tuner in AZ?

 

No idea what it tapers to but I bought it from god (dan) @ godspeed motorspots and he said it would all install fine. guess i will find out.

 

Chris, we always go to pro-dyno...they are good guys and know whats going on with tuning....When you get back into town let me know and we could take a run by there. Later, Mark.

 

Awesome Mark, will do

 

I have the same test pipe...it doesnt taper...its 2.5" all the way thru. Time for a 2.5" exhaust!

 

Pro Dyno is cool - but doesnt have an A/F Meter (as far as know)

Ive been to Street Flight which has real good prices and an A/F Meter...but you basically gotta do your own tuning.
Technodyne also has an A/F Meter now but they are a little more pricey.

 

Are you serious? F!cking eh!! Dan told me I could put all the stuff on. I am not happy...

 

U can put all the stuff on, but it will sound like a tin can going down the street, because of the 2.5 to 2.25 connection.

Evil GS-R,

Why will it sound any different with a 2.25 exhaust?

I'm also about to install a test pipe to my 2.25 Comptech exhaust ....
