How effective are resonators in exhaust pipes?
I have a Cobb tuning cat back. The sound level is just the way I like it...not too loud. However, after I installed a downpipe and got rid of the 3rd cat, it got a bit louder than I'd like.

If I had a shop add a resonator to the straight rear pipe, would it do much to tone down the volume?

More resonators would impede the flow velocity of exhaust gases though, right? And that it turn would hurt performance? Just curious

If it's properly design, there shouldn't be much of a loss.
It's a give or take. If you want quiet, you'll have to sacrifice a little performance.

Happy Motoring ...BlueMax

I had a friend with a 5.0 mustang with headers, no cats, no mufflers, only a resonator on each pipe. It did calm the exhaust down. Pretty mellow at idle. WOT was a different story. It should help your situation out.
