hey, i am going to go and get a new single exhaust put on my 1961 235, it has a stock manifold, and I am going to put a 2" pipe? i have heard that flowmasters sound good? i want a mellow tone, nothing brash or irritating, espescially on the highway. I would like to hear the motor more than stock though. tips and suggestions? i am looking to not spend a lot of money on the muffler, but sometimes this must be done. I am gonna get the new pipes hung for $100, and he will put in whatever muffler i bring him. I just dont know what to put in.

I'm in the same position. I am going to need a new muffler very soon, and don't know what to buy. Like you I would like a little rumble, but don't want a lot of noise. I have seen flow masters refered to a number of times on this site, but I don't know that is? Can you tell me what they are? Allen

I have Fentons on my 261 and this summer I put on new exhaust including 50 Series Flowmasters (not supposed to be as loud as the 40 Series on the wife's 327. I really like the outcome.

Allen - A google search for flowmaster mufflers will get you more info than you would ever want.

FortKnox,
I've got a Flowmaster 50 (supposed) to be quieter on a Jeep Cherokee with the 4.0 I6 engine. Not!

I have a red cherry bomb on my 261 and it isn't very loud. The stock manifold really quiets things down. The nice thing was the the original round muffler clamp fits it just fine.

I was at an Advance Auto parts store the other day and they had a display that might help you. It was an audio center where you could push a button and hear how an engine sounded with the 6 different aftermarket mufflers they carry. It helped me quite a bit in selecting the correct muffler for my 66. The right sound sure makes a difference.

If I were to go with a single, I would just get the one that's a good deal. The sound difference in single mufflers coming out of a stock manifold is minimal. If you want music, you gotta go duals.

My two cents--I took my 54 235 to Tuffy. The Manager has a rod and suggested cutting the pipe before the existing muffler and fitting it into a Flowmaster with duals coming out. Custom bent two pipes out with chrome tips. I lost my under-bed spare carrier but iwa was going anyway.Looks and sounds great. My only do-over would have been to replace the exhaust pipe from the manifold out, since my Tuffy guy welded it into the Flowmaster.Total cost was about $250

you dont want my opinion of flowmasters.lol i had a muffler shop, and have done exhaust for many years. for me,the flowmasters are too hollow sounding,and i dont like the way they decieve people with there advertising, but a lot buy them because they like that sound. the real issue is what are you looking for,and what are you willing to give up to get it.
in a nut shell, the less backpresure, the more top end you get. the more restriction, the more torque. i put on one of the mufflers that i make on my honda...(yes honda) and it killed it off the line. but great at high rpm. im thinking a good glass pack on mine. give it the old school sound. my 2 cents worth.
