Both 1 7/8" Kooks cat deletes.Any idea which long tubes they are running? I'm curious to find out if there is any power difference good or bad with the 2" primaries. And if so at what point.
Does your exhaust neck down from the mid pipe to the H or X pipe at the slip in flanges.Hoping to get mine on the rollers soon. I have the Stainless Works 2" primary headers no cats.
What other mods did you have with the whipple when you made 725 on pump?(Just for reference, on the same dyno on 93 with the same fuel system I was capped at 18* and running the 3.625” pulley it put down 726/565 STD correction.)
Nothing else different than what I listed that I currently have on the car. It was tuned by Alex at Lund for that setup as well. 3.625” pulley and 93 with lower timing. I wanna say I had the stock PP wheels/tires on the car for the dyno so I wouldn’t have my drag radials on the dyno.What other mods did you have with the whipple when you made 725 on pump?
Corsa headers, JMD resonators, and the rear section of a Magnaflow street catback.What headers do you have?
