Well I got pulled over for my custom megan racing catback earlier today so now I have to change my exhaust. I already have the 2.25 back from the cat so I am looking for a muffler and tip. I know that the muffler on the Magnaflow catback is a 5x8x18 oval body muffler, so I am looking at that. My question is should I put on a resonator after the cat somewhere to quiet the exhaust down. I don't want to hinder the flow that i have now, and I still want to keep some of the performance I gained. And also with this I would like to quiet down the cruising speed on interstate cause thats where I got pulled over, damn staties meeting there end of the month quota!!! Any input from you guys would be great, and one more thing, I want it to look stock as possible. Thanks in advance!
