Re: tailpipe/kitty questions

Regarding higher performance cats, I have Stebro cats (link below), but if
the cost is similar, I might try Random Technology next time, mainly out of
curiosity - their claims are pretty admirable. If they're true, you might
realize some extra performance. I realized a slight improvement in spooling
and power with the complete Stebro system (cats all the way back). How much
I'm not sure, but perceptible, at least. And the sound is nicer (mellow,
not raucous at all). Someone on the list had recommended RT a while back as
a good high-performance option for cats. I have no experience with them -
anyone else? I would replace both if you opt for a freer flowing
aftermarket design.
