Steel pack direction
 

Hey guys...
For everybody running 17" (or any size really but I got the 17") Brockman steel packs are you facing the louver openings forward or rearward and how much does it affect the sound. He labeled the inlet on each muffler but it has the louvers facing rearward. Just not sure how much it's going to quiet things down.
The car in reference is a '49 club coupe with an 8BA if that matters

I’ve got Brockmans on my car and they were put on as marked…..if it’s too loud I think their advice is to use a longer muffler……..Mark

Re: Steel pack direction
 

So he marked them with the louvers facing rearwards on yours as well? Just wanted to make sure it wasn't a slip through the cracks on my pair

Re: Steel pack direction
 

Why not just call them & ask?

Re: Steel pack direction
 

They're labeled correctly from what I'm learning. I'm just trying to find out how much quieter they are with the openings facing the motor

CJStefan,i dont think you would want to second guess brockmans build and lableing of in/out markings.i'm thinking your looking at the design of the baffles the same way i did and thinking to yourself if exhaust are traveling over the smooth bumps/ramps vs into the scoops hows that gonna work? the way you have decribed the brockmans soundes like same industry wide spiral stamped louvers. hope i made some sense. google varyous motorcycle aftermarket muffler baffle design. . oh,i wouldnt turn around with openings towards engine the sound you get might not like,and might be too much back pressure.

I'm going to do a Sound test today as soon as my band clamps come in. I'm going to fire it up with just the headers and the head pipes, Which is what I'm running now. Then I'm going to throw the mufflers on with the pipes through the crossmember holes the way he has it labeled and see how much of a difference it makes. I think it's too loud still I'm going to flip them around with the scoop facing forward and see how that is. The problem is I moved to a street Where all of my neighbors are 65+ years old and I get off work sometimes after 11 PM. Since this will be my daily driver I don't want to bother everybody When I come home that late

Sound is one thing but performance is the other. The flow is terrible with the louvers open towards the engine and the freest flowing muffler made with them facing aft. Tim

On my 32 roadster, I turned my Brockman muffler steel packs backwards. Great sound!

Re: Steel pack direction
 

Well fellas I got them on and they really do quiet it down with the louvers opening towards the rear. I planned to try them facing forward but I'm just going to leave them as is for now. I appreciate everyone's input

Re: Steel pack direction
 

I have 22" long Brockman's and found them a bit too loud. Being familiar with baffles for motorcycles, I bought a pair that are 8" long. They are inserted at the very end of the exhaust pipe and held in place with one bolt. I am pleased with the result.

If it is too loud you are too old!

Re: Steel pack direction
 

It's funny you say that. Just yesterday I took a piece of 2" seven foot exhaust pipe, cut it in half and flared the ends to replace the mufflers with straight pipe. That'll get me just on the other side of the crossmember so I can have the tailpipes made up
