New Exhaust, quiet or growl.

I've got DT headers and a custom cat back that the PO installed on mine. I love it. It can be a bit loud on the highway but it's still quieter than my old 80.
 
Stock level quiet for me. I think about rolling quietly into a campsite, or generally being stealthy off-road.

Louder exhaust is fun for about the first month. I've regretted most of the "performance"exhaust system installs on other vehicles I've owned. Exhaust mods can create a droning noise, which normally is most noticeable at highway speed rpm's which gets annoying on long trips.

New exhaust fitted. I asked for a mild sports note in the end, after picking it up I drove it to the highway and got it up to 70mph, no drone or noise, tried accelerating hard, still no noise, thought it was back to stock which wasn't an issue, but then driving slow, dropped the window and there she was gargling and growling. So perfect, windows up and it's tranquil, Windows down for that V8 sound.
 
This is kind of a tangent, but I'm interested in replacing my muffler or whatever else it takes to get rid of my "exhaust booming" that I have at idle and 2400-3k rpm. When I'm stopped and warmed up, it sounds like there is a semi truck next to me.

Did your cruiser have any of the booming before, and does it now after replacing the exhaust? Also, any details on what kind of setup you got? I don't want anything loud, just possibly a very mild growl vs stock if I'm going through the trouble.
 
I didn't have booming before, I took the weight of the chassis as it wasn't doing anything, but I do know these cruisers suffer with resonance that's why they started adding weights to alter the frequency. The new exhaust was hand made so not sure what they used, but sticking my head under the truck they have stuck to the same layout as OEM, the big resonator has gone and there is a smaller box in its place, plus there is the box at the rear as before, I guess there mufflers but not sure, they hand make the mufflers/box's also on site to suit, or so they said. The tailpipe now exits the vehicle straight out the back with a round chrome tip.

The reason I had them build this exhaust was down to cost, it was a lot cheaper than OEM plus with a lifetime warranty. The shop is only 4 miles from the house so I thought what the heck, my old boss used to use them for his rally cars and it always looked good. My main concern was noise, I am a believer that no one puts more time and money into design than the manufacturer so was sceptical to get it done. My plan was to have it as quiet as possible but when they asked and assured me they could get it right, I let them add a mild sports note. There is no booming, from the exhaust and the gargle/growl can only be heard with the windows down, it's not that loud it just sounds like a V8 engine now. There is a different sound in the cab but no louder than OEM with the windows up, 70mph it's as quiet as before. There's no performance gain or lose as I can tell. So impressed with there work so far, I will wait a while before I make my final assessment as it will take time to settle in.

Some would like it, and some wouldn't, that's the thing with sound. But it will turn more heads for sure.
