OK, thanks for your help.

Yes, I have a 1998 V70 with a B5254S 168hp engine and 140K miles. Recently replaced the muffler, catalytic converter and all pipe with Bosal stuff, but put in by my local shop who did a crap job. It sounds loud and rumbles, and I am looking for quiet and smooth. I have had Midas check for leaks, and ...

I hate to be dumb, but what did you replace the rear resonator with? My V70 is too noisy, and your suggestion may solve the problem. Thanks.
