A 5x11" magnaflow will do you good. Or as its better known the 22" big body magnaflow. Quiet on cruise and loud at wot.

Do you have one of these mufflers on your truck?? I have been looking into changing my truck over to a magnaflow system.

Yup. Heres a link to kinda see what it sounds like.

Actually it might not help because its dumped before the axle. On my brothers boosted 5.3 the same muffler is quiet enough to hear the turbo spool at full throttle with the windows closed lol.

Sounds good what are your cam specs? ( PM them i you would )

Cam specs are TSP 220/581/112. Its a little big for a 4.8 even with a 3200 stall it could use a 3600 or a 4000 stall because it starts to really shine at about 3800 rpm.

Not a fan of the XL models. They are not true straight thru flow.
