What to do,what to do.... X pipe or not? Never Say Never Opinions please
I'd get the X-pipe because in most cases you'll see more of an improvement with a good crossover than with a muffler change (unless your mufflers absolutely suck to begin with). I would also sell the Summit mufflers on eBay and get some nice Dynomax Ultra Flos or Super Turbos, depending on how much Summit brand turbo mufflers go for.
