I ran turn downs on my Cuda for about 3 months. It sounded good, and the car loved it performance wise, but I couldn't stand the excessive noise in the cabin and the dust that kept getting stirred up and getting all inside and outside the car. I went back to tailpipes/tips. 0.02
little update I think I'm 80% done here I got the pipes cut down and the mufflers moved up to where I want them of course, the second one i cut before the bend, so i got to weld that back on and cut it again when the tips come in on friday I'll do the final alignment and install the hangers I think I might be able to pull one of the front spring perch bolts out on each side to bolt the hangers down with the pic with the pipe sticking out the side is just a scrap piece to show where the tip will end as you can tell I also had to adjust both 45s to suit me a bit better didnt go to bad considering I was using just a little fluxcore welder
I kinda like the NASCAR dual side exit, out the passenger side. Buddy has 30" Cherrybomb "truck muffler" glasspacks right off the header collector and nothing after that in a cammed 351C 72 Mustang. Loud as hell, not terrible on the highway but when you stopped at a light the car would shake and people would roll up their windows. Forget drive through's!!!
I was going to do side exits on mine but ended up just going dumps, might change it depending on the sound after I drive it for a while. Great job, looks good.
just came back from a very essential test drive I love the way this sounds (might be the pypes though, hadn't really driven it since I put those on)
Dumps can be beneficial. They do clear leaves from your driveway in the fall, just angle them outwards a little. Always get a chuckle when I roll down the drive. And on some setups having pipes sticking out from the sides or rear detract from the overall look and are just excess baggage.
incase you decide you're getting too much heat from the mufflers Exhaust System Insulation | Hotrod Hotline
thanks I mostly did it for looks, but your right, she ain't heavy (I always felt the valiant grille is a good combo with the 71 duster tail lights)
I have my dumps turned sideways, since I have minimal ground clearance there, they are way too loud outside of the car, they just blast the noise right at people. I'm going to angle them down as much as I can to try to an calm them down a little.
Definitely a personal preference, a little trial and error to find a happy medium might be all you need without resorting to more drastic measures. I’ve read a bit on angling them in towards each other can help cancel out certain frequencies, but have never tried that as I’m content with my setup.
THIS If I live long enough to get mine together, I'd like to imitate AAR / TA. My old RR had GREAT side exit they were 2 1/2 that came parrallel under the rockers, then 45'd out and were angle cut to parallel the car sides. Had an H pipe and cross brace at rear, entire thing dropped out of the headers in seconds. That would be difficult to do on an A unless you found some THIN mufflers, or duplicated the AAR /TA method, of mufflers with in/ out same end
Maybe no one will read this but undercar exit sucks . In my state the exhaust must exit behind rear axle for ovious reasons .
I've run cars with dumps just ahead of the axle. It's ok if it's a tack car or for local cruising but gets old. Ontario requires the exhaust to exit from under the vehicle so I made my exhaust as seen in the pics. Got a 2 1/2" mandrel bent kit that had enough pieces to make 2 complete exhausts for $180. Running some 12" cherry bomb glasspacks and exiting in front of the rear tires. Just put a slash cut on the pipe and everything is painted high temp flat black. It works for what I wanted and was way cheaper than any premade exhaust kit I could find.
