gsr header and down pipe, unknown tespipe and unknown cat back. it was all on the car when i got it. and "this si"? wtf, u sound like i never had one or sumthin. when i got the car it had all of the said above except it had a dc 4-1 header, then i sold the car and bought it back, when i bought it back it had the gsr header, rest of the exhaust was still the same
