Greetings, I was wondering if anyone here has a walker BTM on an otherwise stock exhaust on a 99-03 7.3. I currently have a muffler delete, and the truck had no kitty from the factory. I love the sound, especially the turbo whistle, but have to have a SVA (vehicle inspection) before I can register my truck here in the UK, and the truck can't be any louder than 100db at the tail pipe.

So, what does the walker btm sound like, and how loud is it? Anyone up for posting a sound clip?

Thanks in Advance!

The BTM is a great upgrade from the stock muffler and is not loud at all,it has a nice rumble to it but flows & sounds great. That's one thing I didn't get a sound clip of and that was when we had the BTM on our 7.3L for almost 4 years till we went Magnaflow in summer '06.

The BTM had to be approved by the other half as she didn't want anything too loud on the truck for she drives it primarily but it passed with flying colors.

your local napa has them branded too. depending on inlet and outlet diams, your part numbers may vary. on my 7.3, it was 3.5 in and out, NAPA 21470 Walker BTM. a good counter guy will hook you up. iirc, it was in the $50-60 range.

Right on! It is indeed a very good muffler that produces the exhaust flow and sound most can appreciate especially if you have sensitive neighbors at 5 am :sweet

I have the BTM off our Excursion put up in storage till I off load it to someone local looking to upgrade from the stock muffler.
