Did a muffler delete - may need a resonator recommendation

I had a resonator delete...then decided i wanted to get a muffler delete and weld back in the resonator but it can't be done....car sounds great...of course got a bit of drone....one VERY odd thing is the drone got better like the ECU adapted to it or something??? That sounds strange lol!!

Question is this...what is a god resonators or 2 to put in where the mufflers where....has a bit of rasp.

Probably should have jus got the HPF exhaust but this delete does not sound bad. I would upload a clip but windows movie maker stopped working and I can't find a good program to upload HD (MTS ) files.

Since you're going to put it in your muffler delete piping you'll need to know the OD of your new piping. Different shops install differently. The good one use the same size ID piping and swedge (stretch) the resonator to get a snug fit. Some other shops rather you get a .25" larger ID on the resonator and just slide it on and weld it. You def need to know what size piping your dealing with first though. Stock is 2.25" IIRC. your muffler delete may be 2.5"

Actually looks same as stock which I think is 2.25". I would swing it by a reputable exhaust shop though to make sure. They'd be able to give you the part # of the resonators too.

resonators do not help with drone. That's what mufflers do.
