A friend is looking for an exhaust systems for his 2001 Cummins. Current one is broken (rusted) completely in half. There are so many out there. I thought maybe you all might be able to help. He wants to go stainless and probably 4". let me know which one you found to be the best after looking at whats out there, I'd appreciate it. he will probably do it himself, so something thats a simple bolt-on application, would be great.
Thanks
