427 stoker muffler recommendations?
I run spiral flows over the axle and it's loud but it doesn't drone bad, and I haven't had any issues yet even when parked next to a cop at a stop light. This is for a 408 with 12:1.
I also have some Dynatech split flows that I run right off the headers for track use and they're are suprisingly quiet at idle and part throttle. I would think that they would be pretty tame if they were run all the way out the back

I can confirm that the modified super 44's with the 3.5 inch pipe in and out is no restriction at all, I dropped the exhaust off the car this past weekend and the car didn't go any faster with it off then it did with it on.
I did go faster, but that was another change I made that netted the results, intially off the trailer it ran the exact same, 9.8x @ 139 like it has all season.

What rims are you running on your car. Those are nice looking...

I run dumped Dynomax bullets on my 418 car and it sounds amazing, soundslike someone just unleashed hell. I am also thinking about changing to a dynomax setup on my WS6
Mine sees DD action usually 2 days a week. I dont mind it at all but I am kind of crazy like that

I have done alot of research into this for my 430 LS7 with ATS Tri-Y headers and 3" exhaust. I settled for the Flowmaster 50's but was strongly considering Borlas. Car Craft did an extensive research article on about 30 mufflers comparing loudness and HP/TQ, the Borlas were #1 in quietness and ranked very high in the HP/TQ catagory.
