I put a catback on my 98 4.6 and the guy down at the muffler shop told me that it was a "full boar" muffler. Its got dual pipes out the back with 4" chrome tips. Its kinda quiet at idle, but when you stomp it, it really comes alive Its got a really throaty sound, just like a ford should. Im thinkin it might be made by Borla, but im not sure. Any info would be useful.
pics of my 98 and my stock restored 53 chevy should be on soon
thanks

i have a muffler and auto repair shop i jonesboro,ark and the muffler you ask about is made in mountain home ark by mountain home exhaust.

 

thanks alot these mufflers sure do sound good. They not the loudest but certainly have a lot more throaty sound than alot of big name mufflers!

When I built my "true dual" 2 1/2" exhaust, I use Full Boar Glasspacks. I Spliced two 24" together for each side so I have 2- 48" Glasspacks on this puppy.

The rest of the system is fabbed from 2 1/2" stainless mandrel bends, all inside purge tig welded. It has a very deep, quiet rumble. I don't like the sound of chambered mufflers and they tend to resonate in the cab.

The one downside to glasspacks is that they will surely burn out due to the very high exhaust temp but when they do, since I now know what it takes to give me the sound I want, I will replace them with two 54" (I built the system so that I have room) all stainless steel packs that will last indefinitely.

I wanted to test the sound with 50 bucks worth of mufflers before popping for $400 and finding out that I didn't like the sound.
