08 duramax exhaust help
 

I just bought a stock 08 duramax I'm looking to put a 5" turbo back exhaust on it but all they sell is filter back. What do I need to do to do this and where can I find what I need to order? Also is there any other things anyone recommends doing.

Duramax 5" turbo back exhaust
 

Most any muffler shop would make you something you would like but that may be a bit more expensive then doing it yourself.($575-$1000). Here's a link to something I think fits your description. http://dmaxstore.com/products/?route=product/product&product_id=24

2008 Silverado 2500hd cc 6.6 with a 4" lift on 35s, 5" turbo back and Efi live tuned for 440hp

You can go to our website we can offer information that you will need to get your truck done up.

Typically the 5'' exhaust is a little drove to it compared to a 4'' Just my 2 cents.

Just Google it lol there's pages and pages of companies you can order from. Get rid of the the exhaust and the EGR system. To do that you'll need a tuner EFI live is the best I think. Lots of people write tunes but if you research a bit you will see there is some big names that are well worth the money. Get a good cold air intake. For the EGR get a full EGR delete kit it's worth the money in my opinion it comes with the passenger side up pipe and intercooler pipe which on a stock lmm motor is all apart of the EGR system. Get a good lift pump it will help the entire fuel systeem. A fuel rail plug is a cheap but awesome investment specially when you put a tuner on. A pcv reroute Google it. With the lift pump it's smart to get a sump kit for your fuel tank. I couldd go on lol
