DML,
My experience with big Cats (Sam Ps) says put a 3"inlet outlet cat on an
loose your bottom end... Mike Leach's guy Tom alluded to this as well. He
felt the R/T cat is a very good high flow design. Dont know about the 318
unit... If you go high flow cat you may need to increase the restriction in
your muffler... Strange I know, Ive always looked to reduce all
restrictions as much as possible in my "older" Mopes, but all I can say is
be carefull!!

Subject: DML: Bigger Cat?
With all the talk about Headers, Shorties with bigger Y pipes, and front Cat
pipes for non R/T Daks, etc... I still see the cat as a bottle neck. Anyone
Know if there are any high performance upgrade cats available for our Daks?
(
this may be a stupid question)
I have heard Hot Rod guys talk about getting cats with bigger openings, but
what the hell do I know about Mods. I just got started doing this stuff.
Another question is, if you want true dual exaust do you need two Cats? I
have seen a 1987 IROC Z28 with something that looked like two cats.
