good find. i knew flowmasters were junk, never realized they were THAT junkie.

 

Known they've been junk for a long time. There was a thread on here not that long ago about switching to the Magnaflow muffler and getting some good gains.

 

I've looking to get a new muffler for my car and I was pretty much set on buying a flowmaster for it,but i guess I better do some more research on mufflers.

 

it depends on which one you get tho. the multichambered ones dont flow well, but the single chambered race flow ones do ok. Lot louder tho than the other series

 

Not to mention a flowmaster 80 series for example is going to choke a 383 WAY MORE than a stock/bolt on 305/L98.

 

exactly. hotter the motor the greater the exhaust flow demand

for mild setups, you dont need a whole lot of flow. I replaced my 80 series with a chambered tube powerstick that is suppose to flow something like 700 cfm, and i gained very little at the track if anything at all with my bolt on L98

 

I just like flowmasters for their sound, and the look of those cool tips that come with the american thunder catback

Still, straight pipe is looking better and better. The more cars I hear straight pipe, the better I like it. Lets you hear the natural sound of the motor with all the little clicks and pops that give an exhaust tone its character.

I do still like the sound of the flowmaster 80 though...

 

i was set on buyin the american thunder but now (not cause of this thread) im buyin a magnaflow i just sounds better to me also i knew flowmasters didnt flow that well from what iv heard.
