Well I'm definintely itching for an O/R x pipe right now, and I'm a little torn. At first I thought it would be Dr. Gas all the way, but now I'm having second thoughts. I'm sure it would sound great, but it's significantly pricier than the UPR. I also may get LT's some day, so I don't know exactly how much I want to spend. I've also heard that because of how high up the crossover goes on the Dr. Gas that with Sportlines it scrapes a lot. Would it just be easier to go with the UPR, or does the sound/performance gains of a Dr.Gas easily outweigh it?
