Baffeled headers ??
 
I am runnig straight headers on my 1935 Ford Rat rod (460 big block ) , has anyone ever ran motorcycle baffels inside the tips of the header pipes and do they work very good ?

not sure about motorcycle baffles but they make auger style inserts for headers that supposedly improve power over open headers while reducing decibals not sure about the power improvement part but a circle track buddy of mine swears by em since the implementation of muffler rules at the local tracks

Just look on ebay..." motorcycle baffles", there's all kinds of baffles for different diam. pipes.

i found some inserts , by a company called Patriot that i think will work. Thanks for yalls reply

superdime 10-28-2012 03:36 PM

actually i think patriots are the ones i was talking about i see them in speed catalogs all the time

steveb1124 10-28-2012 03:56 PM

yea but the smallest that i have seen is 3" ID and my pipes are 1 1/2"
Id . I am going to try and call Patriot tomorrow and see if they will build them for me as i will need 8 of them .

superdime 10-28-2012 06:34 PM

ok so i was thinking you had collectors the ones i was refering to are collector inserts sorry about that if patriot can't do it i honestly don't see a reason why motorcycle baffles won't work as 327 nut mentioned ebay would be your best source for a good price but they may cut power a little don't quote me on that but from what i know about motorcycles most are tuned for a specific amount of backpressure so the baffles are probably gonna be a bit restrictive good luck though and let me know how things turn out because i would like to do something similar as what your trying when i get to my own rat project i've always loved the look of zoomies but don't like tickets...sound police are pretty strict in my area happy rodding!!!!!!!!!!!!

steveb1124 10-29-2012 06:53 AM

yea , i want to do some more research on the motorcycle baffels , if Patriot cant help me out. Thanks for your input.

A friend of mine had zoomies on his street rod; they were sort of a 'street zoomie' I guess you could say. They had what was essentially a cup with a hole drilled in the bottom; inserted in each pipe. Think like a spraypaint can top with a hole drilled in it.

T bucket guys have used motorcycle baffles in custom headers for years. They will burn out and need to be replaced so make sure you can remove and replace without much hassle.

Not sure if they still make them, but they used to have a baffle for straight pipes that looked like a washer with a knob on one side. Took a single 3/16" or 1/4" hole in the side of each pipe to install them. A 1/4 turn on each knob would close them to restrict sound, or open them to make them straight pipes.
We used to make them up ourselves also to save money. Weld a 1/4" all thread rod to the side of a 1.5" washer, then drill the exhaust and feed the threaded rod through the pipe. Put a small spring on the outside, then a nut, and lock it against a wingnut. You have a cheap, easy baffle, that can be turned to either direction to quiet it down, or leave it noisy.

Post back after you get this resolved and let us know the results. I'd be more interested in the power loss than the noise issue...
