i know in CA the CHP has done checkpoints for roadside inspections. if you get caught you're in a load of sheit. maybe the fines and negatives of getting caught should be listed too for the noobs.

Well, I wasn't encouraging getting away with it in the states that do have emission control. I was actually suggesting they go and get racing cats so that their cars can be legal on the road.

I think it's worth noting for California board members, running headers that are not C.A.R.B (California Air Resource Board) approved are illegal whether you run cats or not. This is according to California Vehicle Code 27156

http://www.arb.ca.gov/bluebook/bb99/VC/27156.htm

C.A.R.B. Approved headers are exempt from this (I know of no approved headers for our cars) Dinan produced an approved header for the 2000-2003 4.9L M5 and Z8 but thats all I could find here:

Personally I think this is stupid if you can pass the tailpipe sniffer you should be allowed to modify it. The only way around it here is to find someone willing to 'help' you pass or swap your old manifolds back on every two years for the test. I haven't been able to find the penalties for the offense yet but there is a provision that says if you are found guilty of 'willfully' breaking the law the court is to impose the maximum fine. I'll see if I can find what that is.

Great information TheBirdmanJD!

I understand what you were trying to say Alex. You're always informative, no worries.

good job Ken. now if there was only a way to make everyone read this...

answers a lot of questions, definitely should be a sticky

i'm interested in knowing how much those of you who paid for a mechanic ended up spending for the labor?

what race cats should i be looking at if i buy ebay headers?

PM AdamBath, he made a suggestion in a thread, I forgot.

hottexhaust.com and vibrant.com both sell cats you can use for this project. if im not mistaken they will need to be 2.25 or 2.5 inches to fit. you are probably going to want 300 cell although im not sure whether they should metal or ceramic core(i think metallic).

good luck

You guys are all welcome for alerting trader-nas

if you plan to go forced induction then metal core is what you want. if you don't, get ceramic. the metal core is 300 cell, the ceramic is 400, at least on the 2 sites i've seen or personally recommended.

if you want ceramic, vibrant has the best price. if you want metal core, http://www.hottexhaust.com/search_re...ottexhaust.com

Thanks for putting in your 2 cents Adam,

Go Ken Go!

Racing cats will dampen the sound a little bit, correct?
