Hey, Andy, I like your avatar and the "water reflection" -- I keep forgetting to say something about it.

Hey, Billy, the drone isn't too bad actually -- but maybe the longer distance to the muffler in the extended cab helps, or the turndown under the truck -- don't know.

Besides, on the highway, I usually have the radio up so loud I can't hear anything ANYWAY...

But it sounds GREAT and I was able to use my same wrap-around clamp that secured my Dynomax. It had pips welded to it that were the right size for my turndown and cat pipe to slide over so I haven't welded it -- just clamped it to the stubs (which were welded to the Flowmaster.)

I no longer have "rumble envy".

Interestingly, where the band wraped around my Dynomax, the outer shell was completely rotted. Doesn't matter much as that part is decorative with the Dynomax name pressed into it. Below that is the real "structural" shell of the muffler and it was intact. But that thin outer wrap rotted through in the 3 years since I mounted it.

I expect this Flow', even though an "oldie", to last a long time -- they're very well built.

holy **** 5 cats thats nuts i thought the 3 mine has was weird. but i glad to hear you like the flows.

Yeah, it's to get the LEV status I think.

The catalytic reaction is "exothermic" - it gives off heat. But, conversely enough, it needs heat to start.

So, they have spread the catalytic reaction out a bit. Below each manifold is a string of 2 cats that are basically there to keep the exhaust hot. They are pretty small. There's two on each side of the 3.0 engine, so that's 4.

Then you hit the y-pipe, and after a short section, the main cat. It's more efficient getting hotter gases to begin with, so that helps keep the NOx emission in check, I suppose.

S'okay though -- I feel "socially responsible" driving an LEV. But it gets cancelled out by driving something that gets lousy mileage, lol...

AWESOME. I mean, if you've heard these on V8 Mustangs and what not you know how "big" the sound can be on them. It's just not "big" on my truck, lol. "Bigger" than I had though, so I'm happy!

I did manage to tear it off over the weekend and ran without a muffler for most of Saturday and all of Sunday on the Centralia trip. The sound was only obnoxious INSIDE the cab with unbelievable resonance over about 4K RPM.

I've got it back on now and WELDED to the pipe, and the support strap that used to go around it has been cut down and welded to it. It's not coming off easily NOW.

My friend's 98 cobra has 2 flowmaster 40 original flows on it, dumped, its sooo loud, and so throaty. Awesome sound, the flowmaster + v8 is the best combo. I think I'm gonna do the flow on my ranger, but I'm scraping up funds between tires, tint, exhaust, and a new box for my subwoofer lol. I thought that by getting rid of the svt focus and moving to a truck I'd lose the mod bug, well i guess its just in my blood lol.

If sound is important to you, get the dual outlets and have something done up. Trucks the same as mine with dual outlets are louder and deeper than mine -- but I couldn't be bothered with all that, lol. Still, if you want a nicer sound, do the dual outlet.

Hey, a mod is a mod. My tag line has been "muto vel pereo" -- loosely translated from the Latin it means "mod or die"...

It's definitely an addiction...I'll bet if I went from my Ranger back to my old Geo Metro I'd mod the hell outta it LMAO!

Bob, yours was probably so loud because you had it mounted right under the cab.. I imagine that would be terribly loud! Mine is more or less in the stock location (under the bed) and its not obnoxious in the cab at all. Its not lincoln-quiet in there, but its not annoying (now the rattles and gear noise from the Hurst.. that can be annoying.) I have a single-in dual-out with 3"x12" stainless rolled tips. I forgot what it sounded like from outside until Kara took my truck to work this morning (I'm doing some minor maintenance on the Miata,) it sounded GREAT going down the road. :)
