Hello! My brother in law just picked up a 91 LX w/ flowmaster dumps that we need to get through emissions so I need one of the following

1)to buy a complete cat back or trade the flowmaster dumps for a cat back w/ tail pipes
2)to Buy a set of 2.5 mandrel bent tail pipes

Also, if anyone has a stock H pipe for sale(cheap) or that I can borrow for a week or so, please let me know!
