So my res. went out in my gtp right along the side joint on the body. I want to do it cheap because I don't really have the money but don't want it to sound like crap. How bad does it sound with a glasspack in its place? I would put the longest one in to help out. Also, I think my cat is clogged so I plan on doing a 3in dp sometime or gutting it and putting in a u-bend delete. Idk what do you guys think. What is the stock exhaust size. I thought I read 2.25 or is some of it 2.5 too? Thanks.
