Cool! That is good advice. What about the rear cats im reading about?? Cut em off?? Also, when you say run true dual dumped, does that mean run dual pipes to the rear??I would honestly just get 2 mufflers and run true dual dumped. Just cut off the stock mufflers and put on 2 mufflers. Any free flowing muffler will work fine. Borla Pro XS are pretty quiet, 18" magnaflow is quiet but sounds great and dynomax bullets are loud. You just need to decide what sound level you want but I'd for sure do the true duals.
