I recently installed a set of long tubes on my car. The driver's side isn't too bad, they actually fit nicer than some brands of shorties. The passenger side is a different story. I need a mini starter, and the knock sensor had to be relocated. But, I installed long tubes on a friend's GT Mustang, he gained about .25 over his previous shorty headers. It went from a best of 12.959 to 12.707. MPH went up 1.7 also. I'm hoping for similar gains on my own car.

 

I just installed a set on my 383 - '87 IROC. I hope to get a small gain too in HP and torque with the long tubes. My passenger side was tight too near the frame of the car. I have no knock sensor, carbed car. I reused my stock '87 starter too w/o any problems. I had room to wrap it too with the high temp starter wrap material.

Which y-pipe did you use? Which cat back? Maybe share your exhaust system design!

Did you use the Model 2210's?

Thanks!

both of your cars must be stock hide...
after slamin mine to the ground we rewelded
headers so they dont hit the street..can u send a pic or post one ? i would like to see how it looks from below! i used a ministarter to get more space and to start the huffer..lol

 

Actually, I am fabricating a true dual exhaust system. It utilizes Spin Trap oval exhaust tubing for ground clearence. As far as ride height, I have Eiabach pro Springs on my car. It is pretty well slammed. I used the 1&3/4" primary headers, with a 28" Length, & 3" collectors. But, I'm ditching the stock starter. It is right up against the collector of the passenger side header.
