Got my exhaust on!

[RoyBoy]

Just got done , MBRP turbo to exhaust brake, (kitty disappeared), left stock muffler on (ok pick on me Robert), went good, just had trouble getting joints ahead of the brake to seal tight(35 psi when braking). I got some 3" wide stainless 2 bolt clamps and sealant, perfect.
Then for the test drive...
the WHISTLE!!!!
Without the rumble and roar it sounds really nice, just some WOOSH and a lot of WHISTLE!
Needless to say, I like it!

Forgot to mention, to Mark and the others at DPPI!

not tryin to hyjack this thread, but bama, where did you get your train horns? That's the next thing on my shopping list!

you really do need to get rid of the muff man!! MAgnaflow makes a great one with either one out or two. It is by far the quietest one out there that is a straight through type. It comes in SS too. IT is the one that i have been using for a while now on customers trucks as well as my own. All you hear is the turbo and it is a quite as the OEM one at idle. Just my 2 cents.

HOW ABOUT OPEN EXHAUST!!!!

Loose the muffler!

After debating on the name brand mufflers, I decided to go with the Walker Big Truck Muffler, branded by NAPA. My 2000's stock exhaust was in good shape, has a few more years left on it. Aluminized steel was ok for me for now.

I broke loose the oem muffler, and cut the hump pipe right at the muffler. I added a short piece of pipe (actually a 3.5 to 3.5 'adapter') to lengthen it and reach the hump pipe. I cut off the stock hangers and reused them by welding them to the new muffler. A little bit of creative smithing required, but acceptable.

The NAPA P/N for 3.5" is 21470 (38" oal), 4" 21471 (36" oal).
The 3.5" was like $60 with tax.

Whistle is HUGE now. At first I thought I may have broken an up-pipe connection somewhere since it was sooo loud.

Its not much louder than stock, and way quieter than no muffler.

everybodys hateing on that on that muffler..... my neighbors would kill me if my truck was any louder in the morrning

Exactly the reason the mufffler stays. I work late often, leave early, etc, and don't really appreciate the roar of the free flow mufflers. I might check into the Walker sometime.
