Diesel Exhaust

I want to make my new F-250 a little more like me (loud and proud!). The old F-250 gasser had glasspacks, but IIRC GP's won't work on a diesel very well.

I'm thinking about an MBRP kit for later on, but right now I'm debating on having the muffler cut out and putting a "test pipe" in its place until I can swing the kit. This mod is commonly called the "muffler delete".

I've heard it will cost anywhere from $30-$50 depending on where I go.

Does anyone know what it will sound like compared to a kit or stock?

I've asked on The Diesel Stop, but I'm wanting some unbiased opinions.

I have a 99 psd with 4 inch exhaust all the way from th turbo back. i still have the muffler. i cant really tell that much diffrence in sound. but i havenoticed a pick up on top end and the egt's wont get as high anymore. although without the muffler it sounds great. i have heard several around town that dont have the muffler and i like it. i just dont need allthat niose. but if you going to mod the exhaust i would get the 4 inch downpipe and go 4 inch all the way back. it will help you out bigtime. the turbo's life hinges on heat and the 4 inch pipes will reduce that bigtime.

Yeah I was just thinking of running muffler-free until I get the required $600 for the MBRP kit I would like to get.

Lose the muffler. If you can weld and have a chop saw it's not hard to make your own exhaust. There is no way in he$$ I would pay $600 for an exhaust system for a truck.

I don't think it will pass inspection if I take out the cat.

Mine has a cat. Some of the 99-03 Superduties have cats also. I wonder how Ford decided some should have cats and some don't?
