Running through an open cutout with just a lid, TBB, FRA! and 3 inch Y I made 332 hp & 340 TQ on a Mustang dyno. I am getting ready to install Pacesetter coated LT, ORY, and Hooker catback. What kinda gains should I expect without a tune from the above mods and are most of the gains going to be up top or do they come throughout the power band? TIA Car is a '00 TA

My car gained throughout the entire rpm range. I gained 35 hp from just headers and ORY, with no other mods or tuning.

felton had a nice gain, but you should expect throughtout the rpm range, about 25 HP is the avg gain

you should feel it throughout the rpm range. I felt it pulled harder up top.

shouldn't you lose some low end power?
