I'm building a 10.5 to 1 440, 582 lift ultradyne solid cam, eddy heads,

i was wondering about mufflers, ive always used flowmasters but was told that magnaflows sound better and flow better as well, any one have experience with magnaflows? thanks guys

I like the sound of the 2 chamber flowmasters. Some like dynomax and borlas. It all comes down to personal choice. Lots of YouTube videos of muffler sounds.

Hooker Aero Chambers better sounding and less HP loss..

Do a few Google searches and you'll come up with the various flow charts. Personally, I'd never run Flowmasters or anything that is that restrictive. Dynamax Ultraflows.....they flow almost as well as a straight piece of pipe.

I added a 3" X-pipe and Dynomax Ultraflow mufflers to my TTI step-header equipped 360 and picked up! It ran at least as well before I took out the 60 lbs the exhaust system added to the car and re-tuned the carb.

X-pipe probably helped and I'm sure the mufflers didn't hurt.

summit 3" cheapo's. Not sure how they flow but you can look straight thru them and they sound good.

are these the mufflers you have?

Summit Super Turbo's are the best $25 you will ever spend. Had them on my wifes vette since 2003 and they really are the perfect tone and volume. My son used one on his firebird, i dont think you will be disappointed.

The Summit cheapies sound great on our Challenger.
