Anybody insert 'baffles' into just plain 2" exhaust pipe?

Since real estate is a premium under my A coupe, I have been thinking about making my own baffles and inserting them in the 2" exhaust system, that way eliminating mufflers themselves. Anybody try this? Will it sound like a fart in a pvc pipe? (don't ask how I know what that sounds like).

PS- and by baffles I mean building zig-zagging plates on a steel center rod probably 2 feet long.

 

http://www.spiralturbobaffles.com/musclecars.html I heard these on a model A with a mild cammed 350 Chevy with lakester type headers and a 2 1/4" straight pipes along the frame back to about the rear and it sounded pretty good. I was surprised...

I think that in a straight pipe the swirlin' exhaust air is the ticket. The air is pulsin' allready flat baffles may make a bunch of fart sounds in a row...

Ditto to Yekoms on the Spiral Turbo Baffles. Mount them toward the rear of the exhaust system for best sound and performance.

 

huh !!!!

 

I built my spiral-turbo mufflers, 8" long, into 2 1/2" pipes on a '32 roadster behind a bbc. They sound great!

 

Check out the Car Chemistry inserts. I bought my first set and made the second one with freeze plugs and small exhaust tubing. I know that the roundy round guys have some cheap stuff too. I am running the homemade baffle in 3" pipe with an IMCA insert on the end. Sounds great to me and I get lots of compliments on the sound.

 

this post reminds me of a story my grampa told me.

my grampa got a noise violation ticket for his hotrod's pipes in the 50's

so, he pled "not guilty" to the violation, and on his court day he and his buddies took off their socks, coiled them up, and shoved them into the exhaust pipes.

when the judge came to inspect his car, it ran almost completely silently. so, he got away with not having to pay the fine.

i wouldn't recommend it, but it worked back in the day

 

I just did this with some 8" motorcycle baffles. I have only run it for a couple of minutes as the truck is not yet on the road. It does seem quieter than without them. I did, however, make them removable in case they need some reengineering.

 

A set of baffles/ my own mufflers I made for a customers car.
I used a two inch washer with a 3/4 hole in it, and cut them in half, slit the exhaust pipe, and staggered them.

 

I have the 4" one's from JP Cycles at $4 a piece. Sound good and just the right amount of back pressure...

 

Do a H.A.M.B. search for "cheap stainless muffler tech".........I did it on my "A" roadster pu.

 

That was my first thought when I read baffles for 2" pipes.

 

I looked at the Car Chemistry site and they look interesting. What kind of holes (siize and number) are in the discs? I made my "spiral turbo" type with a 1" pipe and vanes large enough to fill up the 2 1/2" pipes. I ended up having to cap the 1" pipe to get the sound level down.

 

I made a pair for my roadster ,but it has 2 1/2 pipe.. The insert is 34 inches long. Swedged the ends of a 1 3/4 pipe to fit the 2 1/2 pipe , the low on pipe is about 30 inchs ,in the middle of pipe, on outside, rolled a piece of 1/4 rod to form a outside baffle the inserted a 1 5/8 freese plug ,to form inside baffle, from each end and plug welded .. Marked 4 lines on outside of pipe and and drilled 5/16 holes every inch. I 'm happy with results... This should work with a 1 1/2 insert in a 2 inch pipe...

 

34" long, wow! Mine are only 8" long. It could be a little quieter, but what the hell. If it too loud you are too damn old!

 

I made 8 baffles for my pipes. I found a scrubbing pad at the lumberyard which has a weave much larger than steel wool to wrap around the baffles. It really quiets it down considering, I'm running open headers.

 

I used discarded Samson motorcycle baffles

I used the 10 in. Baffle w/1 3/4 in. I.D. for 2 in. Pipes and they have a treaded tab so I could bolt them in securely!

And they are nice and quiet...!

Inside of a hot water heater there are baffles to slow the air flow and transfer heat, find a junker cruising the hood and put out an apb, they are not obstructive but get the air to diffuse nicely and they are built for the caustic environment.

 

Done it with motorcycle baffles and it worked well.

 

You can buy various lengths of chambered pipe on line.
They were used on early Camaros, Vettes, and Shelbys.
Small outside diameter great sound, reasonably priced!
Do Google search ... Chambered Pipe/Exhaust

 

One time a Buddy of mine was run'in zoomies on the street, it was to loud so another another Buddy said He had made baffles before, I turned them loose with My welder and when they were done it sounded like lots of farts in a row, they had taken washers that would fit the 2inch pipe,used one at each end and welded a long smaller tube with lots of holes drilled in it down the middle, they showed them to Me before installing and I thought it looked to restrictive, when finished the car still ran fine but sounded dumb. the spirial type would have been the way to go.

Coiled up chicken wire fencing (the stuff commonly used around flower beds about 18 inches high with the hexagonal holes) worked great "back in the day". Quick and dirty, cheap, great rap when you wound it out.

 

Corvette side pipes had "chambered" tubing. The flow of chambered pipe can vary quite a bit depending on exactly how it is dimpled. I have forgotten who makes the "good" stuff, but some of the chambered tubing available today flows pretty well.

 

Where is "oldrelics"?

 

here....or.... in the shop....

What do you need?

 

I work for an exhaust wholesale warehouse, and a chopper builder buys cheap IMCO gl***packs, cuts the ends off them, and uses the guts in his chopper exhaust. Still sounds meaty, but tones them down to be legal (or close thereof).

he buys the longest gl***packs he can get, and can "muffle" a few bikes with each...

 

Hey Dennis... pm sent... he's right above you! Hahaha!

 

BTTT for exhaust ideas

 

are SuperTrapp 'baffles' any good? probably not very traditional I know...
