I recently installed an exhaust system that I obtained from a car I parted out. It's 2 1/2" from the cat back with the third cat. and resonator removed. The mufflers seem to be a turbo type, don't recogonize the name. The car is not very loud, but it resonates in the cabin bad at times. I would like to get rid of that noise, but don't want to start experimenting with mufflers. I see other posts where the dynomax bullets, magnaflows have been used. Will these eliminate or would I have to re-install a resonator.??
Thanx
