I have a third gen TA with an F2 procharger. I put down 1005 RWHP. I have run 8.88@ 156 with the 4" mufflex system. Car weighs 3700# with me in it. I finally got a decent video from someone to post. I have 1 3/4" super comps with 3" mandred bent tubes going into the single 4" wiwth a flowmaster muffler. I know I could use more exhaust but this is what I have and this is the best video I have to show so far.

This is what I did. I have a turbo 400 with a gearvendords overdrive and a madman torque arm. We got as creative as our skills allowed. I am still working on gremlins but the car works decent with what we have.

Nice!

Got a closer pic of your trans mount?
What kind of headers?

I too have a mufflex 4", soon to be with Ed Quay long tube 1 7/8. In the process of putting them in right now...

Very nice! That is impressive for the size of the pipes!

I have a 3.5" Mufflex system and it gave me another 2mph in trap speed vs. the 3" Banks system I had on it previously. Went from about 125 to almost 127 with that change.

up date, can ran 8.74 this weekend

Thats pretty good. Have you tried straight pipe or thought about duals 3"? My turbo car saw 1.5-2 psi less boost on same wastegate setting goin from single 4" to dual 3". It reduced back pressure tremendously and that had to free up power but i never got consistant back to back runs. Changed to many other things

I know my exhaust is a bit restrictive for my set up, but I just love the sound and the clean install. I installed and used a 4" cut out to bypass the flowmaster muffler and that helped. What the car REALLY needs and will get once the funds permit will be 2" custom headers with 3.5" dual mandrel to replace the current 3" then I will cut the floor and have a custom 5" single built to copy the current 4". Gonna be A LOT of work but the entire car has been A LOT of work, that will be next winter. We are gonna try and wring out as much as we can with what I have. I will post pictures when I get it on the lift.

Rather than cut the floor what about that oval type pipe (cant recall the mfr name),guys with high powered lowered guys/circle track guys run them a lot.

Car runs hard, nice!

Ugh stock 305 here. Just going to back out of this big boy thread.

Very nice Maria, video had me shifting in my chair. Thanks for sharing.

Got a closer pic of the trans mount?
