I wanna hallow out my cats. My only question is has anyone removed them before or gutted them out before? I currently have a muffler delete and that's pretty loud, not drony on the high way at all. Just wondering if it will be like obnoxious, will it pop a lot more ( which i want ) , and will it drone at all.

Thanks!

 

Hella drone and be obnoxious

 

My friend hollowed out his cats. Took forever and a day to do. Tons of drone. Save ur time and piece of mind and just get FI RHFC.

 

Highly recommend NOT doing this. High flow cats for sure.

 

The stock cats have two honey combs each one before the 02 sensor and one after. You can remove the one after the 02 sensor and get a little bit more flow with out any drone or check engine light.

 

Don't hollow them.. just get a HFC or a RTP..

 

^^ What he said. Far more economical to just get HFC's.
