Frank,
I knew these were in the pipeline and that's quite a product to be offering. I guess you must have spent quite a while developing these.
Have you any data regarding power loss compared to your conventional silencers ?
It would be interesting to see what kind of affect they have. I guess its a pretty tight squeeze to get CATs in. Are they dimensionally very similar to the conventional types ? Can you post some pics ?

Yes Martin, quite a lot of time and cost in development, therefore I wont be publishing internal design, but I will show you next time you come to the shop, Frank
We have had these available for the last 2 years.
Thanks

TESTED - 93.5 Db, good result with no loss of power!

That is a very good number
Is that from headers back or just the silencer that you modified?
Presumably Lambds bungs in the silencer part.
Probably time for a trip down and quieten the Rover mill down considerably fro my 106 / 107db at 4000 at SVA

Frank,
this sounds great.
I'm a little confused however, because I thought cats required lambda probes integrated with the ignition system to advance/retard timing, and also to potential control mixture if a FI engine.
How could I make use of these on a carburated engine, what else do I need to change, and what sort of ballpark figure would this likely be ?
Sorry for so many questions.
I should add I'm a big block user too, so does that rule me out for being able to use them ?
Many thanks,
John.

John, call me to discuss, too involved here, Frank
