AMS vs. UR vs ?? catback systems
just go with you gut feeling.....
i when through 2 cat back till i settled with AMS...
both UR and AMS are amazing exhaust......
just know that 3" piping means louder sound.... i am running a 3" test pipe with the AMS 3" catback people can hear me 3 blocks away at 3500rpm.... soo keep in mind how loud you want it... now with the UR option its a bit more.... but you can have up to 3 mini mufflers... and that will help it out to keep the tone down....
so either one you are choosing there both great products...

here's a pic, looks pretty good imo. not my taste personally, i still like the dual look better, but this at least looks like its done very well and would be a good option for those who prefer single exit. now if only i could find that thread...

edit: finally, here ya go. in case you decide to go single exit, looks like a great option if you have the skill and the patience, or know somebody else who does:

I have an AMS hi flow cat for my AMS catback exhaust. I could've used the stock cat though. I get a SES light now because of its high flow...
I have to get the o2 sensor extender to eliminate the light. You can just get the catback and have no SES.
If you do AMS catback, boost pill and reflash. Your car will beast on stock EVO X's.
