i got my new mufflers in yesterday, so i slapped them on the header extensions to see how much quieter they would be over the summit 3in louvered glasspacks. obviously they do the trick! for 29.95 a piece, a pair of them are cheaper then a single flowmaster unit!
once i get my carb worked out to were it will idle, ill try and post a video of them in action to give an idea how they sound.
with 4ft of 3in pipe into glasspacks, dumping at the axle, the car was extremely loud, louder then most cars with open headers! needless to say, street driving was a bit nerve racking. now with these bad boys, she is way quieter, still a little loud, but not crazy loud cops showing up at 6pm loud anymore. worth looking into if your on the hunt for some good mufflers, and dont want to pay $70 a piece for the name.

engine is 11:1 stroker, with a 6.25 lift mech roller cam, not really a quiet street setup, but it is now!
check em out. many sizes and offsets.

one more pic.

 

they are a nice peice.i put one of thos on my wifes 94 camaro......nice tone and way cheaper than flowmaster but designed similar

 

got a pair on my car and they do have somewhat of that flowmaster sound but not to much. and in my opinion they are alot quieter than my dynomax bullets thank god

 

I was thinking about getting these its either these or magnaflows at friggen 78 bucks a pop! My cars got a 355 long tubes and dual 3" exhaust to the rearend, flomaster 40 series. It is cop calling loud and I am deaf and get a headache everytime I drive it. I need a quieter muffler, these thrush's will do the trick and still sound good?

 

its possible but check out magna flows 14419 mufflers....... im going to be getting those eventually when i have some dual run again on my car...... but for the money the thrush mufflers arent bad

 

but are they quiet?? this thing is like open header race car with the flowmaster 40s

 

if your looking for alot quieter then pony up the loot for the magna flows...... the thrushes are indeed quieter than the 40 series but only by 1/3 or so......

 

yeah I need it to be 1/2 as quiet.. I got the magnaflow on my '89 sounds awesome and its quiet but thats a catless catback (single 3") but same motor with shorty headers though. Obviously dual 3" to the rear gonna be louder. I'd get the magnaflows but not sure if im gonna keep the car or not.
