I did a search on test pipes and FI but could not find any articles. So my question is who is using a straight pipe(test pipe) with FI whether its a turbo or a SC? And if your using a Vortech SC does using a straight pipe affect the Vortech black box(computer) settings.

 

Why do you ask... I had a straight pipe when I had my S2000. A couple of the other 'Speedcraft' guys are probably running straight pipes as well.

 

Because I'm running a straight pipe. Just want to know if they felt the difference.

 

Alex, if you want to sell your test pipe, I'll buy it.

Mine is SC and straight pipe, couldn't feel the difference

 

On turbocharged cars there will be a difference between cats and no cats... probably won't be near as noticable on a supercharged car.

 

I have a turbo and the cat caused a power dip after going into vtec which could not be tuned out and cost about 15 - 25 peak HP. It had to go!

 

turbos work off exhausts gases so changing the piping on a turbo car is different on a SC car. There will be a difference on a SC but really it's unnoticable just like on a NA car. Minnimal gains. This is why you can run a SC car with normal 2.25" diameter piping and to benefit for a turbo car you should have 2.5 and higher preferrably 3".
