Would it throw any kind of code or mess any ting up if I were to put a straight through pipe where the converter is now? I have an exhaust leak and I thought about going and ordering one for the extra power since I will more than likely have some junk apart in there anyway.

 

you mean a test pipe, and it shouldt throw a code as long as it has o2 bungs in it... sometimes however, you need to use spacers so the 02's sit a lil further out of the pipe.
