So im thihking about skipping the exhaust system and just getting a c ut out, does anyone have one or have any idea what the gains are like
got a sedan, why comptech manifold?Do you have a coupe or an sedan?
If you have a sedan you are in great shape for my suggestion.
#1 get a B pipe for a coupe, this allows you to move your cat 2 inches back and allows a better location for the e cut out.
(you will have to extend o2 sensor wires though)
#2 you want to cut your down pipe as close as you can to the cat
#3 install the y pipe with e cut out just in front of the cat.
#4 buy a comptech manifold
