I'd vote for a custom mandrel-bent exhaust, IF you know of a reputable show to have it done at. I'd agree with the guys who bad experiences with custom stuff, because the shops that did them were probably ghetto. I had my custom exhaust done at a good shop here in town, and not only was it inexpensive ($225), it looked stock, sounded great, and didn't make me spend 2x or more on a useless expensive unit.
