I'm thinking about swapping out my muffler with a magnaflow. I've read every thread on every brand. I've been wanting to do an upgrade for 2-3 years now. I know most people use a 5x11x22 muffler with 3" in/out. My question is: Do I need a muffler that has center in/center out, center in/offset out, or offset in/offset out? I'm thinking center/center but I want to be sure before I order it. I definitely want to keep a resonator but is the stock one very restrictive. Should I upgrade to a magnaflow as well or just stick with stock. Thanks
3" center/center is your best bet. about the resonator, i dont know. im doing my new exhaust this week. i bought a 4" round magnaflow and i'm running it out the side, so no resonator for me.
If you do not give a damn about drone then chopping off the resonator is fine along with an aftermarket muffler. If you dont want my super crazy/obnoxious loud I would suggest a 5 X 11 X 18 Magnaflow muffler with no resonator. Like I said if you dont want drone then leave on the reso.
This is a little different because I have a 4.7 but I've run a 5x8x18 and a 4x14" round muffler, but the round sounds WAY better. I would go with a round Magnaflow and keep the reso.
I'm planning on keeping the resonator. Should I upgrade to the magnaflow or just keep the stock one. New muffler and custom 3" pipe will be about $150 at local shop. Add $80 for magnaflow resonator. Still about half of a catback system.
I have the 5x11x22 with the 3/3 center inlet/outlet. It's perfect for cruising.. quiet most of the time and kinda loud when you get on it. I would recommend going down to the 5x11x18 if you want sound more often. I have the res on still and if I got the 18" I'd still keep it on if unless you want MDS drone. Let me know if you have any questions.
thank you for posting the video. i wasn't sure on inlet/outlet. the stock looks like it's offset for inlet and center for outlet. if you're running center/center then i have to believe that works.
