New exhaust installed, Dynomax rebate!!!
I was considering the true dual system (discussed in the parts for sale forum) that is available now, but the lack of completeness (no mufflers) and cost stopped me.
I went ahead and got a Dynomax catback again. The $75 Dynomax rebate and having a leftover $50 Summit gift card from Xmas made the decision easier. I originally installed a Dynomax kit on this car 10 years ago, when I first bought it. When the mufflers rotted out 5 years ago, madrussian gave me his slightly used Flowmaster kit, and it has been fine (but loud) for the past 5 years, but it rusted through at the flange joint at the beginning of the Y-pipe. When I took it off, it was barely attached at all. The mid-pipe hanger was barely attached to the pipe, also. I think the mufflers stayed in such good shape because of the paint I put on them after I had installed the system (I didn't want the visual rust I had seen on other Flowmaster kits). So, I have a pair of MN-12 specific mufflers that will probably go to the scrap pile soon (unless someone wants them bad enough).
So, it's a good thing I saved the short pipe that the 96-97's used in place of the resonator. I still had it in my treasures bin. The Flowmaster kit eliminates that pipe or the resonator on the 91-95 V-8 cars.
As usual, the Dynomax kit fits extremely well. Nothing bangs on anything, even if I put my receiver hitch back on. Other than some cleaning that I did while I was under there, and the difficulty in getting the old rusty Flowmaster stuff off, it only took about an hour to install it. I did some prep work beforehand, removing the paper tags from the pipes that came with the kit, cleaning them with prep, and spraying the whole system with hi-temp paint. The welds on the y-pipe, the hangers, and where the stainless tips are welded onto the mufflers are not aluminized, so they would have been rusty in a few days. I also used the stainless band clamps again, instead of u-bolts, except for the one that Summit sent me the wrong size (the 2-1/2" one).
Sounds good, not as loud as the Flowmaster kit, but still a pleasant "adult" rumble. If I want a Mustang sound, I'll buy a Mustang. And as much as I gripe about all the friggin' unmuffled V-twin motorcycles around here, I'd be a hypocrite if I had my car too loud.
