      so thats on OE pipes? that sounds pretty dang good

      i bought my muffler off amazon but i realized i got 2.5 inlet outlet one when the oe pipes are 2.25, the shop will still be able to work with that right?? i was just gonna get a 2.5 tailpipe installed with it but if thats how mine will sound with oe pipes i might just blow it off.

      what are the pro's and cons of clamping a muffler, i figure I could do that myself and then just buy a piece of straight pipe and run it out the back, save on the shop costs.

      I've clamped mufflers before. As a matter of fact, the ones on my '69 Cougar were clamped until a couple months ago. I say "were clamped" because when I backed it off the trailer, the clamps caught on the edge of the trailer and ripped both of them off the pipes. I saw it coming and didn't care. The full exhaust is getting replaced.

      But that's one of the downsides. A good rock may rip it apart. Not a real big deal because you can just crawl back under there, reseal and clamp it back up.

      Another down side is that I was never able to get a perfect seal. I used every product I could find to seal it, with muffler repair kits over top of that, then clamped...I just never got a perfect seal. Again, not a big problem, just something that I noticed on my Cougar. Probably had more to do with the rusty pipes I was using.

      The good thing is that it is really easy. It also serves its purpose.

      Really, though, it cost me $30 to have the shop weld it. If it was $30 for them to clamp it, I may have still considered letting them do it just to save me from having to break out the sawzall, sealing, and clamping underneath without a lift. I don't have a lift anymore or I would have welded it myself. It took less than a half hour and they did a solid job. I'm betting the shop costs are worth your time and effort for this project.

      When I had my exhaust put on the guy installed the clamps sideways to keep that from happening.

      Doh! That would have been smart. Why did you have an exhaust guy clamp on mufflers though? Can he not weld? Or did you prefer clamps?

      Actually, after looking at mine, there is still a clamp at the inlet of mine even though it's welded. Eh, I've never paid much attention to exhaust.

      Well. I kind of figured it would not be as good a seal and when I was sitting in deep mud or water, it would leak into my muffler so when I change my muffler I'm difinately getting it welded in place.

      1. It's a Gibson cat-back and came with clamps.
      2. It wasn't done by an exhaust guy, rather at my bud's transmission shop because he has a lift. I gave him a pair of $20's and some donuts and me and him had it done in a half-hour in the morning before he started on his regular stuff.

      Ah, makes sense. I think clamps would work just fine on most applications. On my ST, it would have led to mud/water getting in the muffler. I avoid mud every time I can, but there are instances where that just isn't possible. Gotta be prepared for that. On the Cougar, they have been clamped on until recently. Now it's just sitting. When I finish the engine rebuild and do the exhaust, I will have it welded just because it seems more appropriate for that amount of money and time not to have any leaks in the exhaust.

      The quiet idle is why I liked it so much. It does get a little louder after it breaks in. Sounds really good over 3k RPM. Did you have the resonator removed?

      Agree with Hugh (OffTrac), regarding "break in". A gradual, but subtle loudness increase, over time. Fiberglass insulation will slightly burn off. I have the same combination as robzilla. My SCT tuner, Zabteck throttle body, and K&N drop in, enhances the sound more. Listened to a lot of mufflers with the 4.0 SOHC. Don't recall hearing a deeper or more pleasing tone, with minimal drone. The best bang for the buck I've spent yet. Dynomax Superturbo rules! Enjoy!

      I've had my truck in muddy water above my 32" tires so a good seal is a must.

      Hello all,
      I need information on the new muffler for the 2018 Ford Explorer Sport, now it has a split dual tips on the rear (quad tip) and I want to put an aggressive sound muffler in it (Flowmaster Super 44?), but I need to know the dimensions of the inlet and outlet on the 2018.
      Also anyone in STAMFORD, CT are who knows a reliable Exhaust shop?

      Appreciate any input that will help me find and add a muffler to my new Sport.
      Thanks
      LCL
