[neomorphin]

Only a little not very noticeable at all. I do have a diablo tune on it though so no afm. I started with the axle back on the camaro and decide to contact borla and get the xpipe for it and it was a huge difference. I also added the npp diffuser and quad tips. Very happy with how it came out. Lt headers and hi-flow cats are next on the list at some point.
