exhaust for my Gen 1 997.1 Turbo, and hv been looking around Europipe, Fabspeed, and GMG. Just a few questions before purchase. Hope you guys could help.
If i purchase those cat bypass (Catless)
1. Will it trigger the Check Engine Light?
2. Would I be able to put my OEM exhaust back when I need to pass the emission test?
or should I get those cat??? Thanks!!!!!!!!!!!

1- Yes u will get check engine code with catless exhaust.
2- I guess yes you can.

Do u have a reflash ecu?

I have the apr ecu...so wt I am required to do. What does reflashing ecu mean?

Both r same. I believe u won't get check engine code since u have APR ecu.

I will contact the dealer to confirm then. Thanks!!
