Do a google/yahoo search on Merge collector, several magzines have done articles/tests on different types, I read alot before I redid my exhaust...

Mine is still slow, thinking about adding a little sauce to it....

 

tick tock tick tock tick tock your little 4.8 days will end

 

With a reverse cone the collector starts to look like a 2 stroke expansion chamber. Same theory right?

 

check out this article

good article, but this was with no exhaust. So, I think the real world might be less exciting. $600 for collectors only? They sure are pretty.

 

i need to redo my exhaust...it's the gay.

 

Hey Guys, I thought I might let you know that we're now offering header systems for the 2007 and up full size GM trucks. Like all ARH systems, these will all have merge collectors standard. Look for a new thread with pics sometime today. If any of you have questions please contact me directly at 631-608-1986. Thanks.

Nick

 

will you offer them in 1 7/8?

The design is called a De Laval Nozzle.
It's used on rockets to help increase the force of exhaust flow.
