according to his first post he has a 05 5.9l. the only 5.9l in 05 was the cummins. So unless he got the engine size wrong then it is a diesel.

 

Then Cummins it is...still say CAI along with exhaust

 

Woops my bad. My eyes skipped that part. I say a tuner and exhaust

 

yes it is a diesel 2005......i bought it with a tuner....edge attitude. i was looking at a magnaflow muffler.....they K&N cold intake and a intercooler intake ...what u guys think? sorry i was so slow ran a half marathon and my mother in law came in today

 

Well if you want advice on diesel mods I would say head over the Cummins forum. But everything you listed there sounds like basic gas engine mods and idk how well those brands are for diesels

 

Look into Banks for mufflers and CAI.
