Hello fellow Ranger enthusiasts.

A quick one sentence summary for those that don’t like to read:
Is the flowmaster super 40 a decent exhaust choice for an upgraded sound on my daily driver that wont irritate other people and wont irritate me with too much drone?

The Rest:
Recently ended up with an exhaust leak and when I took it to a recommended local shop for a quote, it came up in conversation that I wish my Ranger’s (4.0 SOHC) exhaust had a little bit of life to it. Based on what I told them, they recommended the flowmaster super 40.

Now, everyone’s opinion on exhaust tone/volume/tolerable drone/etc is going to be different. That much is obvious on browsing threads here and elsewhere.

However, I’d like to get some opinions that are at least a bit more geared toward my specific situation.

What I told the shop I wanted was “an exhaust note that can actually be heard, but isn’t going to bother anyone”. What came to mind for me was how it sounded on a cold start in the middle of PA winter.

Something important I neglected to mention to the shop, which I will before Saturday’s appointment, is that this is my daily driver and I don’t want to have to deal with an annoying drone in the cabin.

You may say “why not just stick with what you have if that’s all you’re looking for?”. Fair point… however… I live in a place where rust and salt is plentiful. The muffler isn’t lookin great and I’d rather just hit it all now. They quoted me 390 to fix the leak and throw on the super 40 which sounds good to me. I just want to make sure that it’ll literally sound good to me.

All opinions/suggestions are welcome.

are you not a bot?



dynomax. magnaflow. borla. last would be flowmaster. but it is a fair product.
 
My Choptop had a regular 40 series on it when I got it. I liked the sound. Super 40 and Super 44 are both supposed to be good sounding as well. When I got new exhaust put on my Choptop I told the shop I wanted all stainless and a 40/super40/super44 muffler. The owners kid insisted on wanting to put a 10 series on it. I’m not a fan of the sound. It sounds ok at idle, a little quieter than expected, but it gets loud and a little annoying when you’re on it.

I’ve had a few el-cheapo Thrush Turbo mufflers on various vehicles. They sound alright but the salt and stuff around here has a tendency to reduce them to a pile of rust in short order.

My green Ranger has a Magnaflow on it. Sounds awesome but it’s also got a 5.0 with headers, lol. It’s a bit louder than I intended and it’s sort of a straight through crossover muffler (which eliminates the need for an X or H pipe in a dual exhaust).
 
i prefer the dynomax welded.

but lil blue is a PA resident and his opinion and experience i would defer to. cops hate my truck in PA.

I will admit to not having tried Dynomax or Borla and my only experience with Magnaflow has been on the 5.0 with true duals (dads 00 Ranger is also 5.0 swapped with duals and a Magnaflow crossover muffler but no headers and is noticeably quieter than mine despite the same muffler).

Stainless everything is the way to go in PA. Everything else rots some degree of quickly. The welded mufflers (non stainless) hold up better than the crimped mufflers like the Thrush, but a stainless welded muffler is the pinnacle.

The “aluminized” stuff tends to last 2-3 years around here for exhaust tube. I’ve been using a local custom exhaust shop around here for years to make stainless exhaust for me, but I think once I have my garage up (and maybe before then) I’d like to get an exhaust bender and start doing my own because the local shop, the son of the owner is becoming difficult to deal with and the father is mostly retired at this point (the father was amazing, I watched him hold a pipe up, make a couple marks on it with a dirty finger, go bend it up and stick it in place, no anfgle finder, no measuring, just 100% eyechrometer).
