I posted this in another thread but didn't get any answers there, so I thought that I would create a different thread for my question.

A lot of you say "unless you plan on serious mods then don't go with an x-pipe." What would you consider serious modding? I don't plan on SC, TC or N2O on this truck but I do plan on putting a mild cam and LT headers on it. Would that be worth going true duals or would a single in/out be sufficient? What about a single in/dual out? Would there be any benefits of going with a single in/out over a single in/dual out? I really want to put an exhaust on my truck but don't want an exhaust that will rob me off power though. Thanks!
