ok, my set up is in my sig, in case anyone needs to know. but the welds on my downpipe and such aren't the best because the guy who did it sucked ass, and so did the welder. anyway, some of the welds blew and i have a shitty sounding leak. i don't like it. well, my question is, i have some money to spend and i thought about getting a 3" turboback exhaust done. do you guys think that it'll improve me as of right now, or just leave me where i'm at? i could also spend the money(i'm thinking probably somewhere along the lines of $400) on something else. either way, the leak has to be fixed. give me some advice please!
