Coolest looking I think is stacks but also only thing I ever had on mine other than straight pipe you can build your own pretty cheap but I hear great things bout mbrp, call Paul at complete performance or cary at ct performance they have great pricing imho, Paul sells me stuff he puts on his own truck.
I got a steal on MBRP turbo back from 4wheelparts with a special they had one week, so I got that one. I have the muffler on it and I think it sounds pretty good. I didn't want my truck to be super loud, just wanted some turbo whistle sound and flow more air. Works well for me.
Diamond Eye makes one that bolts up to the cat with the bell shape fitting,It's two piece of course.If you are just getting started this makes for a great addition and then you could add on as you see fit.I did the DP last year and I'm currently installing the 4 inch cat back from Diamond Eye this weekend with a cat delete also from DE.I made my purchase from Performance Truck Products ,good prices and service.You can check out Diamond Eye's web site and even call them with any questions you have .
