Walker BTM for '97

I'm reading the BTM will almost do about 80% of what a 4" straight pipe exhaust system would do. I however cannot find anyone who has put one on a '97. Can it be done? It shows it is a 3.5" in and out pipe. I believe that is what the stock pipe coming in and out of the stock muffler is. Lookin to make economic upgrades. Got the DIY intake and downpipe materials ordered. Thanks...

Stock (for now) '97 F350 CrewCab 4x4, AT, 140,000 miles

I thought I was the only one that likes a muffler on their PSD. 80% is not that great, but it has to be way better than the stock muffler. The BTM should give you a really deep sound. You could also use a cheaper, smaller muffler and use an extension pipe to make up the difference. The price I saw for the WBTM was $91. You can get a lot better muffler for that kind of money. Dynomax makes one for around $40 and you can get an Ultra flow for about $80. I'm sure they flow better than the BTM.

The BTM is a "Big Truck Muffler"

In my experiences, mufflers with glass or steel packing material reduce mid range and high frequencies, leaving you with a really low town. They have a great tone when accelerating. The bad thing is you usually have an annoying droan while cruising. They also kill a lot of the turbo sound.

I haven't tried all the mufflers out there, but Banks and Wicked Flow fit this category. They sound really deep, but no turbine sound.

My Flowmaster Outlaw race muffler doesn't have any packing, just rings that deflect sound. It sounds a lot like a straight pipe at idle and has a great growl when accelerating. It doesn't have the annoying droan, either. At highway speed it had a rumbling sound, but not too loud to in the cab. Flowmaster also has a new Hushpower Muffler out that should be even quieter than mine, but flows near what straight pipe does. I plan on trying one out some day.
