BTW I like the White one also!!! Your pics on another thread helped me decide to go with 10.5" Black FR500 style rims in the rear. Too bad nobody seems to have them in stock right now.
With a chambered muffler, either an X pipe or H pipe will work fine-
Some X pipes dont work well with some chambered mufflers though sound wise according to some on this site-
its really up to you to decide-
power wise if you have a chambered muffler X or H wont make much of a difference-
power wise if you all ready have an X- you want to get a straight through muffler-
if you have an H, you will also see more gains with a straight through muffler-
power wise with a straight through muffler- you will get more from an X pipe-
sound is all opinion- many are willing to loose hp to get the sound they perfer- as there is only 4-5 hp difference between a chambered and straight through muffler depending on brand
