Thrush sound

[Mancar1]

Now that I went to all the fun of installing Thrush in my dual exhaust, 390, did it myself. I really don't care for the sound. Not deep and throaty enough for me. I am thinking about taking the 68 in and having 3" with flowmasters put on. That is if the CS has the space to allow for 3" exhaust. I now have stock size.

I recommend Magnaflow over Flowmaster.

I have had flowmasters on a Ford truck several years ago. Sounded good, but it was kinda hard to hold a conversation when driving. I will check out tha Magnaflow. Thanks BobbyFord.

I recommend Magnaflow over Flowmaster.

i second, i had flowmasters and magnaflows. i putting magnaflows on when i get to that point in my resto

What is the difference between the two? The new '69 SB has what I assume is blown-out cherry bombs-sound good, but VERY loud. Probably need to replace the mufflers, to get back in the good graces of the neighbors! Want it to have some decent sound, but not overpowering...Suggestions?

I have flowmaster 40's, dual exhaust, 429. I don't really like them, but they arn't bad.
They have a "drone" you can ask just about anyone that knows about exhaust and they will probably say flowmaster is not a very good performance exhaust.

I'm going with Dynomax Bullets....search youtube for them and remember. LOUD PIPES SAVES LIVES!!!

I went with Magnaflow, single on the 4x4

I pulled the Flowmaster 40's and put Hooker Aero-Chambers on my 71 and like them. They don't have the dreaded drone. I have set off a few car alarms in the parking lot with it though but that is only if I ride the brake a little.

I put Spintech mufflers on my truck and Ilove the sound. Like some of these guys I've had Flowmaster 40's, Hooker Aero Chambers, glasspacks, turbos, and now these and I can say the Spintechs almost tie with the Aero Chambers for the best sound quality without having any headache inducing drone. The Spintechs are a bit louder and are physically smaller but have a great sound.

BTW, is your engine all stock? 3" exhaust is quite large for a stock engine and you will get some loss of low rpm torque if that's the case. 2 1/4" is plenty large for duals on a stock 390. For the big pipe sound just put some long (18-24") 3.5" tips on her.

That is the word I was looking for. Drone, oh ya, that is the one thing I did not like about those darn flowmasters I had on my 73 Dent. Couldn't talk over the drone. Consider me talked out of Flowmasters. Been there done that. My 390 is stock for now, but I plan on a build to add some grunt, but not to wild. Already been there, my 73 was a little much. If that is possible. I guess I should wait for the oversize exhaust until latter. Nothing wrong with it as it is. Better get my new wheels, get A/C fixed, gas gage working right for dual tanks. Ect ect. Like my better 1/2 says to me, "One thing at a time, and before long it will be done." LOL Like it all ever gets done. Enough for now. I am dronning on. Guess I will go play with the 68.

Also, remember Flowmasters kill HP.

[lovesfords91]

i always thought magnaflow sounded like a mix between a glasspack and a flowmaster.

[1982 flareside]

I have cherry bombs on my 68 they are loud! i would go with cherry bomb glasspacks. Remember disturbing the peace since 1968!

[ccryder2011]

i have dynomax super turbo mufflers on my 67...with a built 289 they sound awsome but are not to loud when driving..they are the quietest in their class but still sound great...i live in condos so the nieghbors like them too
