LS1 Modified Flowmaster Y-Pipe w/02 sensor!!
Hey guys. i've got a Y pipe from flowmaster that i have modified to be similar to speed inc.'s set-up. Goes from a 2.5" and then into one 3" outlet. o2 sensor is still good and did not have any check engine lights. stainless steel pipes. flowed a lot better after the 3" outlet compared to the 2.75" from flowmaster. Looking to get 175.00 plus shipping or local pick up. Thanks
