I have a 2005 2500 Cummins 4x4 and am wanting to install an upgraded exhaust system. I am interested in the Magna Flow Pro Series 5" High Output Cat Back. The engine is stock except for a Bully Dog Air Intake. Any thoughts or recomendations?

don't know that much about Dodges...I went Turbo back w/my 2001 7.3 Ford first then a AFE Proguard 7 Stage II after that. No chip.

I'd go turbo back if that's an option...less bends the better the flow. Magna flow should make an aftermarket Cat if you have to have one. I'd get rid of it if I could...should lower you EGT. Should make your truck "breath" better! Go stainless steel, galvanized whatever can't take the heat as well as SS.

Look into the MBRP exhaust systems. You're best bet for performance is the turbo back systems no matter who makes them. They have 4 and 5 inch systems. Not the cheapest but certainly some of the best.

Call scott at Mass Diesel 508-660-7093

He is the man when it comes to diesel pickups, he won't steer you wrong. I just sold my 01 Dodge 2500 CTD scott built it with me 590 hp 1260tq to the wheels. I have been out of the game for a while and things change fast.

Just get his opinion, you don't have to buy from him, he is a wealth of been there done that knowledge.
