No idea on the cat-test procedures. :-/

 

I meant...take yours out...and run a midpipe..or high flow and see if that helps.........or if someone has spare good stock cat around to throw that in for a try. I think your butt dyno would be good to pickup 40-50HP

 

Ah, annoying. Good luck...

 

I've got advertisements in the local forum for volunteer help.

 

this is my first post on this forum. i am looking into buying a used 8 and am doing a lot of reading on it. this thread mentioned a lot of engine, cat, battery, spark plugs, etc. replacements. is all the replacement covered under the warranty?

 

^^^ For this sort of question you want to start a new thread on the topic. I am pretty sure that wuestion has never been asked.
