Flowmaster: my turn (pics) - Page 2

Thanks to all of you for posting about this. I just got mine done today (Flowmaster 52580) after many days of fruitless attempts to locate a guy that was willing to undertake the project. Last week I went to 5 shops and all I got was "come back next week" Next week came and only one of them was honest enough to tell me that he wouldn't do it. All the others told me the same thing: "Too busy, come back next week"
I got so frustrated yesterday I was almost ready to sell the muffler and pay the $720 and get the Monty and get done with it. But today my luck changed! I found this cool shop, Gary's mufflers, owned by the same guy since the 50's. Told him what I had, what I wanted, showed him the picture and he said he could do it! Took him about an hour. His cost $125. Cost for the muffler $95 brand new. The sound? Un-@#*%ing believable! Jack, Randy, Mike911 you all know what I mean...

I have a Dynomax same side 1 in 1 out. It sounds great and performs great. Not too loud at idle or cruising, but rips nicely at full song. I had a buddy who runs a Meineke shop fab up the pipes and I already had a bracket and straps left over from a B& B muffler.

My Dynomax is part number 17676 that is spec'd here on page 3

and the install is pretty straightforward for a competent muffler shop. One thing I recommend is you politely suggest to your muffler shop guy that he focus on making the pipe from the muffler to the cat/cat bypass as simple as possible. The alignment between the cat and the muffler inlet is a bit offset and makes for some tight bends that are hard to make. So the guy should position the muffler so it looks good, but also makes his bending work not so troublesome.

I also have a Dynomax UltraFlo stainless 2 in 2 out if anybody's interested. It's part # 17276 on page 2 of the UltraFlo SS catalog

PatrickB uses a muffler like this on his OBX headers and has good things to say about it, with good pics to show install

I planned to use this for a header project that I decided instead to use M&K shorty mufflers on.

Looks similar to what I had done with my Flo-Pro.

1 in1out. I love the sound. nice and burbly at idle, burps between gears, and screams flat out.

I sort of went the same route as you guys. I ended up going with a really "pretty" Magnaflow muffler that's 1 in 1 out on the same side. I say pretty because the only Magnaflow that's set up like that is a fully polished ss muffler. I had a shop put it on and have a muffler bypass with it too. It looks really nice, noticed a little torque too I believe and the sound is sort of a low tone and a little burbly. But honestly I wish it was a little louder and not so subdued. It's a little louder than stock and a very "sophisticated" sound.
It might be a little louder outside the car since the tip is sort of facing back but I wanted a little more rawness. It's not my daily driver anyway.
Anyone have a muffler that's too loud for them and they want to trade?
