im about to put a set of pacesetter long tubes on my truck with some high flow cats, and right now i have a flowmaster cat-back dual exhaust...do i need to modify any part of my exhaust or is what i have a good setup for this next mod?

 

Only thing I would do is modify it to be true duals!

would you recommend magnaflow mufflers or is there something else out there that isnt out of this world as far as price?
