I have been researching exhaust options and I am leaning towards the 5" magnaflow turbo back. I have a 06 cummins and have been told that will work well. I have been trying to locate a 7 inch exhaust tip and every place i contact, it seems to be a challenge to them. I saw a post with a 7 inch tip, Where can I get one with a 5" inlet????

 

Are you stock? I'd go with just like a 4" unless your going to be pushing alot of horses

 

CUTTER the new 6.7 come with a 4inch stock i belive. ima steal me one...lol... umm sorry man dont know where to get a 7 inch tip.

 

thats true I got stock 3.5in but I'm a 01 and I just stuck a 4foot pipe in place on mine.
