I have a 2.2 ecotec grand am. I am looking for something performance wise. I have a 2.25 catback exhaust done to just a GT muffler.. I want something with a nice deep sound and not too loud..

well your not going to get a v6 sound out of you 4 cylinder. but maybe you want to try borla or magnaflow or something along those lines.

Id go with magnaflow on your car. I personally just had a magnaflow muffler put on my 2.2L cavalier and it sounds nice and deep with my air intake i put on it, but not extremely loud considering its a 4 cyl.

What kind of magnaflow?

flowmaster 40 series deltaflow

I would recommend any ractive single tip ractive muffler. I have one myself and love it and I have yet to hear one that gives anything but that deep sound you are lookin for.

can anyone tell me if apc single tip muffelars are good i hav 1 on my 2.2l and it sound pretty good i would go with that
