What's the best glasspack to run right behind the header? The Lawman didn't like the fact that I was driving my built 360 around town with open headers. :lol:
 
Hello Dad... Hello Mom...
CH-CH-CH-CH-CH-CHERRY BOMB!!!

I personally never liked round mufflers. When i wanted to build a shorty/removable system, i just used some 2.5/3.0 straight pipe into a good turbo style oval with a cheap hanger on the back. Reasonably quiet with good flow. If this is for your p/u, you got plenty of room to experiment. That's just me, but i'm really old school. :)

I agree, but the o.p. basically asked for a header muffler. The purple hornies bolt up, have the reducer flange and turndowns built in
Have you shopped reducers and turndowns lately?
(I run a full length system with flowmasters on one car, and the longest magnaflows I can get under the car on the other. I'm old, I want em a little quiet. My header mufflers days are long past).
 
I had the same issue back in 1975. Two inspection tickets for open headers. Lucky i worked at a inspection station.:) So i put on a pair of Hush thrush bolt ons. Couple weeks later got another one for no tailpipes :BangHead:. So i decided enough was enough and bought some stock tailpipes from Walker and hung them in the factory hangers connected with a straight 2.5 pipe. Actually turned out pretty well with nothing hanging low.

Most header mufflers I have ran just weren't that efficient. If you're going just for sound purple hornies are hard to beat, but they're all kind of corks when it comes to performance. Most only have 2 inch cores. In my opinion you're better off with a turbo or a chambered muffler.

Strictly just to muffle the sound so I can drive it around town etc. For performance I'll take them
 
Keep in mind WHEREVER the muffler is, that's where the noise and drone will be, especially with glasspacks. They will be right under the front seat. I've found that header mufflers like that are actually worse than open headers. We used to run open headers and header mufflers a LOT back in my school days. Never got a ticket. Hardly even got looked at. But I always preferred open headers. The header mufflers really bring out low frequency that can just bug the crap out of you. If you're going to do anything, I'd get something like Dynomax turbo mufflers and run to the rear axle with turn downs, not aimed straight down, but down and to the sides. That way, the noise won't just bounce right back off the ground.
 
Engine masters recently did a show on turbos and mufflers. Interesting results.
 
Cherry bombs for the win! I even put them on my Gen 3 Hemi! I just like the way they sound. To be honest I do not think there is a lot of difference between them and the purple ones! I always went with the cherry bombs cause they throw in great go fast stickers in every box! And well cost of course. I don’t think you can go wrong with either of them. Purple/ cherry bombs. I mean seriously, as long as both will set off a streets worth of car alarms who cares right? Hah!

The last exhaust that I ended in front of the axle (under the car, that is) I was advised to point the turndowns toward each other at about a 45° \. I was told it helped performance. If it does, I don't know how.
What it DOES do is keep the exhaust from blowing dirt/rocks onto passersby or other guys cars. It actually seems to blend the sound better too.

I've never in my life heard that.
 
Increase performance? Never heard that.
Dampen sound? Yup
Stop rocks from blowing from under? Yup

Why not run a full exhaust with cutouts if you want the option of open headers. I don't think most people would enjoy you running around with open headers, and I don't know why you would like that on the street yourself. There is no reason to be running around open headers on the street.

You know how they are enacting very oppressive exhaust laws in places like NYS?

I'm no bootlicker, johnny lawmaker lover either. I'm more of a f' the police guy myself and I don't like them breathing down my neck with their revenue creating business of promotion based ticket writing

Personally, I run full length 3" pipes with an H-pipe and XR-1 mufflers (round, straight through)
 
A friend of mine has Steel pack mufflers on his Satellite. They are Porter's Porter Mufflers

Steel packed not fiberglass. They last a long time before they burn out.

It was fun when we were kids.
 
I wanted glass packs for my Ford project so I got Summits 3 1/2” and a couple of U bends, my header turn towards the the transmission so there needs to be a bend before the muffler then a turndown after. Between the cam it has 248 degrees of duration @ .050 lift and the glasspacks the the ashtray lids will be dancing and car alarms will be going off as I go by.

It will be as safer than Harley…

Back in the old days, when I was young, I swapped gears and exhaust systems on my 57 Chevy on a monthly, if not weekly basis. I usually put the quiet (sort of) turbo mufflers on with the 3.08s
When the 4.56s were in, I usually had some glasspacks that were basically header mufflers..... only there was NO glass left. Hit them with a wrench, they would ring like a bell.
I'm sure I was very popular with the neighbors.......
