I have been trying to find a hi-flo cat for my 2000 Integra Type R. I put a straight pipe in with a bung for the O2 sensor and have had a check engine light ever since. Any suggestions?

 

Try the T1R Test pipe... or if u have a Aftermarket Exhaust or Header... then call Smsp they can custom make a Cat that will be a Direct fit for the setup that u have... and its about the same ammount of money as if u bought it from somewhere and had a local shop do a OK job when u can get it from someone who only does Awsome work...

comptech sports makes one, and so does random tech

 

i use the carsound 2.5 inch cat

only 80 bucks and works great
