Ok well he patched it up as best as he can. I could see why it was hard to weld it he showed me. There is still an annoying noise that happens upon acceleration. Last year when I took it in he said it was a loose bolt or something like that...after he " tightened" the bolt it never came back untill recently. The car sounds perfect for now anyway untill the patch gives out. The annoying noise goes as follows :

your at a red light and and lightly accelerate and then you hear "kkkkkkkkkkkk"....light scraping noise...thats the best way i can describe it. Doesnt happen above 2k rpms. Once you get below that it happens and goes away when you give it more gas. Also happens when the gears change and the rpms drop. Its very annoying. I think its most probably a heat shield. I think its coming from the right side underneath...when im driving the car with the windows down it seems to be that way. The mechanic said i need that pipe from the header all the way to the main cat....i guess that means i need a new passenger side catalytic converter since its attached? . The dealer told him 500 bucks...i was like yea right. But anyway thats the deal for now.
