Well that's good to know

I've had these MAGNAFLOW 3.5 X 7IN. OVAL STRAIGHT-THROUGH PERFORMANCE EXHAUST MUFFLER 11132 on my car for about 6 years with around 35,000 -40,000 miles on them. I've noticed this summer that they seem louder especially when taking off. Wondering if there's baffles in there that eventually...

That's my car above in #33. Resonators went behind gas tank and tucked up, you can't even see them from behind. If you do see them it looks like back of gas tank. I went from Flowmasters to Magnaflow, better sound but still had drone at different rpm. Local shop dealt with it and did great job...

That I do not :(

"Suggestions for muscle car sound muffler without drone" I went back and found this thread concerning mufflers and droning, there's alot in here concerning what to do or not do. Thought I would throw it out there for info, it's about five pages long.

Pretty hard to see from back standing there

Can't see from behind car unless you get down to look. It looks like back of gas tank unless you look really close.

2" pipe 20" long. They have a formula they use depending on what your rpm is when drone is the worst. He showed it to me, but it was all Greek to me.

Same tone outside of car, inside quieter

I concur!

Pipes are individual for each side. and capped. I guess that allows the sound waves to go down pipe hit cap and when it bounces back it neutralize's sound waves. All I know is that it works.

Took 65 Dart in last week to take Flowmaster 40's off and replace with Magnaflow's to get rid of drone. First off the Magnaflow's sound great, very mellow but nice when you stand on it. Trouble was I still had a drone but now at 40 to 50 in the 2000 to 2300 rpm range, we're in town so there's...

Went with a satin black kinda plain look, no chrome. A driver, have 3 summers with about 4000 miles per summer on motor. Holding up pretty good so far. I like your motors look, sweet!!!

Took a quick pic for you to see before you order. A pint is plenty, you don't use very much

Well I didn't, but some might. I put two coats on with foam brush, let them sit over night put on car fired it up got em hot and let them bake.

I've used POR15 exhaust paint on a couple of cars and been very pleased. Used a wire brush and drill with steel brush to clean up, prepped with degreaser and painted. On 3rd year with 318 manifolds and they still look great.

Just saw your post, just had dual exhaust put on my 65 Dart with factory exhaust manifolds. Took some pics but it's hard to get angle under car, hope they help. 1st pic might be the best, shows how they worked it down 2nd pic kind of hard to see as they worked it over suspension 3rd pic is...

Thanks guys, waiting to hear back from cosgig on a pm

Looking at putting dual exhaust on 65 Dart, was slant six now has 318. Looking at tranny cross-member it's notched on drivers side for exhaust pipe. The cross-member is not notched on passenger side so pipe would have to go below. Is there a different cross-member for V-8 that allows exhaust...

I'll check em all, winters around the corner so I should have plenty of time. thanks everyone!

I'll have to take a closer look at the trunk seal, very possible that could be it.

Yes, full exhaust all the way back

I get exhaust smell in car with the top up (64 Valiant) trying to track it down. I don't believe there are flange gaskets were the exhaust manifold bolts to pipes. I'm running 1964 exhaust manifolds off of 273 does anyone know what size exhaust flanges I would need? 2 1/4 of 2 1/2 maybe? Better...
