Really? my 09 is a pro-4x and I heard they have very good/efficient mufflers for being stock. is this not the case?EXHAUST!
A free flowing muffler of your liking and a new Y Pipe. I had a Magnaflow muffler but had a custom Y Pipe installed. I shaved .2 tenths of a second off of my 0-60 time as recorded by Cipher just by replacing the Y pipe. Best bang for the buck and absolutely necessary IMO.
Unless Nissan decided to re-engineer the exhausts they put on these trucks since my 05 NISMO than no it is not the case. The Y pipe is very restrictive and the mufflers stink too. Take a looksie around the threads about exhausts here there is a ton of information. Good luck.Really? my 09 is a pro-4x and I heard they have very good/efficient mufflers for being stock. is this not the case?

Get the exhaust first. It works WITH the intake. Then get the tuner.Buy a superchips/hypertech/bullydog gt and be done with it![]()
Had my '09 PRO-4X on the lift last weekend to get a custom exhaust quote. First words out of the guys mouth when looking at the stock system, and I quote, "Look at that y-pipe, what a piece of ****." They redesigned nothing.Really? my 09 is a pro-4x and I heard they have very good/efficient mufflers for being stock. is this not the case?
