Exhaust??

Hey guys ive got an 02 f250 and was wondering what would be the best exhaust to have put on? First i bought it and the guy before me cut the muffler out and the cat delete (love the sound). now, i believe its the stock exhaust therefore it would be a 3 in right?? so how big of a difference would it be to a 4 in with no muffler or cat. also a y pipe into a dual exhaust?? i like the sound now but would love for it to be louder. Whats the best way to go?

also, this truck is just a daily driver for me and to strike fear in all other vehicles besides Ford!

It's not going to be really loud like a similar size gas engine. I would get an MBRP 5" turbo back system. I have a silverline 4" and wish I went 5" for both sounds and slightly lower EGT's. I wasn't totally happy with the fitment of the Silverline and the clamps were junk. I would give MBRP a try. Get T304 SS.

I wish I would have went with a 5 inch sometimes to. I like the little deeper tone. My 4" sounds good but after riding around with the stock system with no muff or cat the difference wasn't much.

Ive been told single exits are louder than duals I dunno tho

Stock is 3" diameter until just below the passenger seat and then 3.5 to the tip. The choke point is the stock muffler.

It is very cheap to buy a complete 4" kit from the turbo. Like silly cheap. Though my cheap FBD exhaust has fitment problems as well, it nearly rests on the trans Xmember, and rests against the trans heat shield. Also, the hump over the rear axle isn't big enough to clear the factory sway bar under full compression. Maybe all kits are the same in this way.

MBRP makes theirs out of high grade stainless steel, and it wont rust... but its about $700 for an exhaust.

The guy before me did the same muffler delete and the exhaust was dumped right before the rear axle. I just put on PTP's econo 5 inch exhaust system with no muffler and I like the sound. It sounds a hell of allot better then the stock exhaust with no muffler. It is a little louder but is not LOUD. I have never heard a 4 inch kit so would not know but the 5 inch made it sound allot better.
