Hi all,
I have a 2003 F250 5.4L crew cab with the 156"wb. She has just developed a hole in the stock muffler so it will need to be replaced.

I want something that is an easy-fit, has better flow, and maybe better sounding.

Any ideas?

 

I am real bias.... Ultra Flow Welded. Find out the length of your muffler and we will have a replacement.

Whatever you choose, get a stainless steel muffler.
Most companies will offer a Limited Lifetime Warranty, what sets us aprt is we offer a 90 day Sound/Performance Guarantee.
