Hi My question is can you fit the x-pipe back box only and still retain the oem valve system so it still opens about 3500RPM. I already have the AP headers on would like the x pipe before i get a remap done. Thanks
I have the Fabspeed headers and the xpipe. The xpipe is an easy install, just take out oem muffler and bolt in xpipe. I don't know how I feel about the sound. Definitely lower and more raspy at low rpm. It does scream the way I like it at higher rpm.
