Has any of you modified an R muffler?
 

I was inspired by a post from stubble88!
I have this set which I think is an R combination (?)

Anyhoo, I intend to use it for my new engine upgrade but it is definitely too noisy for the street. (although I'm guaranteed to love the sound I'm sure!) :D
So my question is: have any of you "played" (modified) - with such a beast? and what are your experiences?

Regarts, Mads

Send a PM to Aaron (BURN-BROS). We were just talking about this muffler a few days ago. I think he was quite pleased with the results.

I think your challenge might be the small runners on the heater boxes your biggest challenge.

First: you're a damn cool guy Henry! :)
next: We have a deal! I just need to read up a bit, on those pistons (if one can "design" a bit on them, for one's own specification)
Last: yep, I know they are a bit on the small side ... They were intended for my engine at the time it was going to be a 3.2 l, and more of a fuel economy thingummy.....

hmm ... I have the feeling that I didn't understand you correctly ... is it the Ø on the exhaust you meant, or is it the length of the "collector" style spacer between the manifold and muffler?
