This is a DMH 2.5 inch electronic cutout that i bought for my car and never had the time to install it and i have since sold the car, it is in perfect condition and comes with the weld in Y pipe. The wiring is already setup to a switch and plug and play harness all you need is to run the wire weld it in!! Looking for $160 OBO i need to get rid of it ASAP, bought it for $200 and its still in the same condition as the day i took it out of the box... E-mail is the best way to reach me, hangten93@aol.com
