I GUYS TONIGHT I INSTALL MY PACESETTER HEADER,HIGH FLOW2.25 CAT ON MY CAT BACK
THAT I HAVE INSTALL AND I DONT SEE ANY FLEXIBLE ON MY EXHAUST LINE
SHOULD I PUT ONE OR STAY WHIT NO FLEX?

AND DOES ANYBODY HAD SOME PROBLEM WHIT CHEK ENGINE LIGHT
AFTER A FULL EXHAUST LINE INSTALL WHIT HIGH FLOW CAT?
OR SHOULD I KEEP THE STOCK CAT ON IT ?
AND IF I KEEP THE STOCK ONE WILL I LOST ALOT OF GAIN?

THANKS FOR HELP!

If you don't have any poly motor mounts to cut down on your engine rocking then I'd put a flex pipe in there. I've got the 53035 cat from Magnaflow and haven't had a CEL, but if you get one then search for manual O2 sim to fix that. Basically you use a couple spark plug antifoulers to move the O2 sensor out of the exhaust stream a little.

The Pacesetter has a ball socket style moveable joint so a flex pipe is not needed.




Semper Fi SAINT. May you rest in peace.
