Ok so I need some UDP's for my 04' mach1. It's up in the air between that or getting a catted x-pipe. Anyways I'm having trouble finding pulleys... I was told steeda was the brand to go but on their website and on ebay it only says 03' mach 1 with an * by it. Does anyone know of a widely used brand that can give me some links? Also is it easier to install since the better brands don't us a piggyback system? Finally has anyone noticed much better throttle response out of their UDP's?

Stay away from UDP for mach1s. They cause nothing but problems. I have never heard of anything good about UDP on a mach. Use your money towards something else.

yea what he said^ STAY AWAY FROM UDPs there has been guys on the registry that have compleatly messed up their motor from them and will only gain like 2-3 hp not worth the risk IMO

Ditto. Have never heard anything good from putting them on a Mach but plenty of bad.

do not do the UDP's they will break your oil pump shaft and your motor will the be f*cked

What they ^^ said. Go with the catted x pipe. That should give you a decent hp gainand might even make your catbacks sound a bit better if you have them.
