I want to make my own muffler. I want it to have a trap door to re pack it.
I tried looking up prices but couldn't figure out what kind of sheet metal to use.
Can anyone tell me if its feasible or would it be too expensive?

 

It's totally possible we've been making our own mufflers stainless and titanium. Depending on how far you want to go with producing each piece, I know Burns Stainless makes a removable "cap" to do something like your talking about for repacking. What are you trying to do besides re-pack it? Are you going to slip-roll your own sheets?

 

Try Megs / Cone Engineering , nice guy to deal with . Just off 605 In Los Altos Ca.

 

Dang I have been wanting to do the same thing. Would love to see some ideas from others.

 

Not repackable but this is the type that were making for our 350Z dual exhaust in titanium...
