Performance Exhaust SystemsDetailed discussions regarding performance headers, single, dual, street and off-hard racing exhaust systems for your vehicle.
This is a discussion thread titled "Question regarding loss of power w/ exhaust", within the Performance Exhaust Systems forum, part of the Technical & Vehicle Assistance Forums category.
I got dual FM's 40 series 3"pipe fom the Y connection to the muffler, then 2 1/2" piping from the muffler back. I know I lost a LITTLE on my low end, Im curious is it because of the 3" pipe from the y connection to the muffler? That would cause me to lose a little back pressure. I was wondering if I could take it back to them and have them put in 2 1/2" pipe instead of the 3". Think it'd be worth it?
i have 2.5" and ive been happy. I say go back and get 2.25 or 2.5"
