if your looking for a new mid pipe then i would just go with one for an sn95. i had a bassani catted x that was for a fox and it fit ok. the pipe on the driverside rubbed the crossmember. the main difference between and H and X is the sound. the purpose behind the 2 is to balance the exhaust pulses. the X pipe does a better job of balancing the exhaust pulses to create better scavenging. as far as brand, i guess everyone has their own preference. my preference is DR Gas. the difficulty of installation is more difficult than the rest but fitment is better and sound and performance is better overall. especially the more performance mods you do to your car the more power the dr gas will make.
