right now i got borla muffler everything else stock
i was thinking:
Jet-hot LT headers with 3" y-pipe
now heres the problem
do i:
-buy catback borla so i have new and bigger piping
-run a cutout after y-pipe and keep everything else
-run off-road pipe and replace piping back to borla muffler with bigger pipes

the thing i'm worried about is that the borla muffler will not flow good enough and cause me to lose HP
wat u think, catback, cutout, new piping to muffler?
thanks

 

add an off road pipe. Don't buy a cat back system just for the pipe. a good local muffler shop can fab one alot cheaper. you could also use 4" pipe and use a vise to ovalize it.
