I can't find a picture of the stock midpipe, but if it isn't too restrictive, an axle back might be all it would take to loud it up a bit. A quick google search didn't find any, but judging from the aftermarket cat backs, I would guess one could be fabbed for 2-300 bucks. |
I didn't think about the custom route. But if he plans on doing a full exhaust eventually, just an axleback would be a waste of money, since you usually get a bit of a discount buying the full catback. As far as I know, the Catback is the same as previous years, so aftermarket catbacks or axlebacks should be easy to find.
I agree that el is better than uel generally, but if the aftermarket uel is a bigger diameter than the stock el, couldn't it potentially flow almost as well? I think it could, that's all I'm saying.
