sooooo which downpipe should I get?
Should I create another thread with a poll?
correct. Always install BEFORE the cat since the cat cleans out some of the mixture for emissions and a cleaner air mixture

It will say it right under their username. BlackSS/SC06 and ReignSS are around a lot. Just shoot one of them a pm I'm sure they can see that this is sticky worthy.

You may not be wrong. Putting the o2 before the cat or too close to the turbo is not a good idea either unless you have a heatsink made for the sensor. Too hot of an exhaust gas will fried your o2. This was from past experienced.

You will not pass inspection if you go catless and your state/province requires you to have a cat. If you really want catless but your state/province has laws against it you will have to switch the downpipe back to stock for every inspection.

This its sticky yet?!?
What is the policy in US and other than Qc provinces concerning inspections .. cuz here in Qc we don't get our cars inspected .. unless the police man stops you .. but can they really notice that you are catless?

Thanks guys, I didn't know if the car measured the temp or anything. So I was thinking the car would be like WTF where are the cats? lol I haven't been under the car or knew if there was a sensor or w/e for that. and this should def be stickied btw!

if you are running the stock exhaust, you will barely even notice a differnce in sound even with the catless. It's actually surprisingly quiet, and you will definitely pickup more gains with the catless
