deciding on mufflers for the two td's here....
1) 90 shadow 2.5 dp 3"cat- 3"catback system (installed)
2) 92 R/T 3" dp 3"cat- 3"catback system (not installed)

without a muffler the shadow has a drone on various RPM's and is VERY raspy at WOT. So i want something to fix this and to make sure my r/t wont have the same problem. The drone is the big issue btw

my r/t has the stock crimp exhaust but without a muffler! and it doesnt sound loud at all...

ive narrowed my search down to these few (unless you guys got something better)

1)this add says its a magnaflow, but it doesnt look like one. pos knockoff?

2) straight through oval magnaflow, too much drone?

3)FLOWMASTER SUPER 40 MUFFLER 3" C/C 953045. I've read theres really no power loss. Hows the sound and drone? Any issues with trying to fit this muffler?

I have the 2nd one on my van, drone city but it is a auto and I here the manuals work much better. With a cat, the drone goes away so if your running one, it will be ok.
The first one is longer, so that will work better but be harder to fit.

I liked the sound of the Super40 and it barely droned, much less than my Magnaflow. I have one thats kicking around if you want to try it.

That 1st one is a real Magnaflow, its a 3 chamber muffler, so prob restrictive and quieter.

I have 2 mufflers on my car, just added a Borla XR-1(in place of cat) and a fart can on the end. Its loud, but tolerable, again I'm not used to it yet and my wastegate is open so that gets loud when the boost comes up.

Simon do you have a pic of the inside of teh Magnaflow or describe? This Borla is straight through and has like a "S" shaped baffel the length of teh case thats got lots of holes in it. I heard teh Magnaflow has something similar inside it also?

The shorter Magnaflow I have on my van is a straight thru, just a perforated tube in the center, full of flat holes, like my motorbike race mufflers.
