When did flowmater super 40's come out?

  • Sponsors (?)


Flowmaster was started in 1983, so I guess right around there. It was started by Ray Flugger, originally to make California Sprint car mufflers with low noise and backpressure. I'll assume they had 40s not long after, because I remember as a kid, having uncles bringing their hotrods to family parties with Flowmaster stickers on them.
 
Really, the Super-40's came out probaly around 2 years ago, maybe a little longer.

I put one on my 4.0 Jeep not long after they came out.

They are more tame on the inside than the origional 40's and slightly more agressive on the outside.

They have a nice tone to them. I loved the sound when it was dumped, but it is quiet through the tail pipe.

Ohhhh..... He said Super 40's! I missed that part!
 
You need to understand that the US Goverment Discovered Flowmaster 40's in a secret under water cave where they also found the Mclaren F1 and the Hold Grail


Actually several Flowmaster 40'S were left behind by Aliens after they
finished doing some crop circles in a remote corn field in Kansas in 1951.
They were not welded on properly and fell off thier craft after lift off.
The extreame noise of thier open pipes could be heard for miles.
