Anyone regret adding or removing muffler after a turbo?

For those that have added a turbo and left it straight piped do you have any regrets about the noise level or is it not too bad?

For those that have added a turbo and left a muffler on it do you think it's too quiet?

I'm mainly concerned about 809 trucks with the stack beside the windshield but I'd like to hear all opinions

I just replaced my muffler with a straight pipe on my 936A2 and only at idle, can i tell a difference. When throttled, i only hear the engine, even when im operating the crane, which is closer to the stack than on the 809 series.

Where did you get a straight pipe? Thanks!

Here in Washington state unmuffled jake brakes are no bueno but the big rigs don't pay much attention to those kinda rules so that wouldn't be a deal breaker on going straight pipe for me either.

I prefer straight pipe. My trucks have always been quiet. Plus the Jake's work better than a horn thru straight pipe

I put a turbo on my m923 with 5” exhaust and 6” stack. If I was driving it to work every day I’d put a muffler on it. But for the way I use it, it’s perfect and sounds great.

I pulled the muffler off before I had a turbo and put it back on after one drive. That was absolutely obnoxious.

For now I only drive my truck for fun and maybe put on 200 miles in a year. I wear H-161 headsets while I'm driving so that would seal out a lot of noise.

any pictures of your exhaust from manifold to stack?

I have one of my down pipe. After that it’s half flex and half straight pipe then the 90 for the stack. A section of flex pipe somewhere is necessary.

Late to the talk, I’m in the process of running my exhaust behind the cab, Did the same on my bobbed duece and with the sound behind you it’s not too bad t all. Will post when I get done with my 818
