Mufflers too loud.

Magnaflow is my muffler of choice. They make loud and somewhat loud versions of their universal-fit mufflers. Both versions sound great on a Studebaker V8 and Magnaflow's build quality is much better than many of their competitors. Just my .02 cents.

I'll add to that... I've been running a set for several years and like them a lot. I run the turbo schmurbo style and they have a 2" inlet and 2" outlet. You can drive them quiet, or drive them loud, but they aren't rappy, or cutting at all. One thing I did notice (that may be of interest to you)... On my original install I had a bad harmonic resonance (read that LOUD) range inside the cabin at 2700 to 3200 rpm... Since a lot of the cruising range was there, it was real irritating, and you couldn't talk in the truck. Moving the tailpipe tips back 2 inches completely changed the harmonics and the noise level 'inside' the cabin. You might try moving the tailpipe tips a little bit to see if there is a difference. Just a thought... Jeff (and a free one, too boot) Rice

Jeff's right. Straight-thru pipes can be nice and quiet if you custom-tune the length of tailpipe downstream from the resonator. Either take a cram course in physics, or buy several lengths to try...result's the same...

You might try adding an "H" pipe if you don't already have one.

Kind of hard to do on a coupe when they come out the back. Might look a little weird with extra long tips on them (:-)

The important thing to remember is just to lengthen the pipe, Alex. Doesn't have to be at the end, although that's the easiest way.

You're beginning to sound like Nate Turbo mufflers are a lot shorter than glasspacks. Mine are about the same diameter/shape as the stock mufflers (just shorter). You could add a short hiccup of a pipe in there 'if' you needed it, but I doubt if you'd have to go that far. Jeff

Right, but at that point the discussion was about using only pipe length to solve the problem. Obviously, a new quieter muffler would also solve the problem, I just don't want to end up to quiet. Did you use the 14" or the

Thanks

I used the shorter mufflers, but I'd have to look to see if they are centered or not ( I 'think' they are centered). Jeff

There is no baffling in these mufflers and they are as far back as possible.

try moving the mufflers to rear of car as the reverberation from baffling is what resonates noise (Jeff Rice would be proud of my big words ).

Do you remember the part number?

try straight pipes with a section of pipe 1/4" to 1/2" smaller than mufflers placed where mufflers are now. Placement is a big issue. If you look at domestic full sized cars from 1964 with factory dual exhaust, you will see that GM used a forward placed muffler with a rear reasonator and Ford used a rear muffler. The GM system was quieter and lasted longer because of heat reducing moisture in muffler but Ford sounded better but had mufflers rusting out in the rust belt semi-annually.
