Need Exhaust
 

Looking to buy 5" turbo back exhaust on my 03 duramax crew cab long bed any suggestions on where to find the cheapest one?

5" is overkill for anything with less than 500hp

Post your question in the Supporting Vendors section, they will give you the best price

so what lol


its loud, there are some dyno sheets that show that u loose like 2hp with a 5inch vs 4 inch
