I need some help with my exhaust decision. My engine is a 6.4 (392) fuel injected Hemi and I have a Keisler TKO 600 5 speed with an alterkation front suspension. I have decided to run TTI headers that are made for the alterkation suspension but what to do form there? X-pipe ( will this have clearence issues with my transmission?), 2.5 or 3 inch exhaust, Anyone running Dynomax mufflers (how do they sound). As always thanks for the help. Mark
