High flow cats and boost
Hi guys, so I have ARH HFC’s and wondering if I’m gonna have any issues with boost? 800-900 whp range. I don’t want the fumey smell in car but have seen where guys have had em fail and blow the engine. Any suggestions?
Thanks |

GESI Gen2 cats only way to go at that, or a higher, power level.

I can't find any of the GESI GEN 1 "UHO" or GEN 2 cats anywhere, the only ones I can find are the "standard" no name regular, non-EPA GESI cats, which don't even have a power rating on them.

@Camaro1973 has been running them on his 850+whp ZL1 without issues. He had different cats prior and they failed.

Those things aren’t cheap I know that lol. I was looking at the Gesi non epa ones, they say there rated for 500hp each. Those ones are alot cheaper, just don’t know if they will hold up. I may just got catless and add a resonator or something idk. |

Cheap and modding Gen 5 powered vehicles don't go hand in hand. If you want cheap power LS 5.3 swap a fox body. lol
