i dont know much about magnaflow but im considering getting one of their mufflers. i was running no muffler for a while but got a glasspack put on to pass inspection. it was cheap so i just told the guy to do it. later on i didnt realize he put the wrong size on so my flow is a lot more restrictive. if i got a magnaflow muffler which one is the loudest??
thanks

Check out their website.They have alot of info and sound bytes that will give you an idea.....

 

im just wanting to do a muffler swap. my pipe is cut and the glasspack is a turndown application. i like those round bodied mufflers magnaflow makes but which one would be better for my throttle response and torque, a 4 in. or a 6 in?? and which would be better in terms of loudness??
thanks

 

Here, I just made a quick video for you. Sorry for the kind of bad sound quality but you can hear it idle nice and good. It has the SI/DO side exit before tire, it's the 16616 kit. My new camera gets here in 5 days and i'll make a better video of it then. If you have any questions just shoot and i'll try to answer them.

i like that sound!
which muffler is that?

 

The muffler is just the one in the 16616 Stainless Steel Catback Exhaust Kit from magnaflow. It has one 3" inlet and dual 2.5" outlets.

Here it is on their website:
