SHIFTER OR CAT-BACK???????? Needs Something After My Trip To The 1/4 Mile...

[Rick 91GT]

I actually think the cat back will help you, since you only have dumps at the end of the stock H-Pipe, that motor is seeing no back pressure and will really hurt your performance right now. A nie flowing Cat back and Off road pipe will help. 83mph is very slow even for a stock 5.0 IMHO, I turned 93-95 stock with 2:73 gearing, with the 3:73's I went 104+ on the stock motor. The gears will help also, go 3:73 or 4:10's and get a set of sticky drag tires for the strip.
