So I have the URD y-pipe, just ordered their headers, and I have a flowmaster 10 series. I want my truck louder than it is. My question is should I get a muffler delete? How do I keep from losing to much back pressure? Should I Get a cat back and pipe where the muffler goes? Any advice?

Wait until you install your headers.

Headers & y pipe delete all the cats. That by itself, will make it pretty loud.

this is what im thinking... wont be installing until the o2 sims are in stock... BTW guys, is there any way to bend the exhaust if I go no muffler to help keep back pressure?

spec-u headers with no muffler and cats are way too loud. If you want a good sound, get the spec-u exhaust and delete the muffler. It sounds beasty with a sprint booster in person. If you want loud with the spec-u headers and y-pipe put on a SLP large mouth 2 muffler.

With the specu headers , the specu y-pipe and slp largemouth 2 only gets loud when u want it to . I have tried 3 different mufflers using autozone adapters and pipe. It saved me a lot of money not going to the muffler shop.

The urd spec-u equal length y-pipe makes a better exhaust note.
