Hey guys,

I am thinking about some HFCs, but I have a Borla TD. I believe the diameter is 2.25", so what are some good options? I know some popular HFCs are 2.5" and some are 2.36", but does anyone run HFCs on their Borla TD equipped sedans? I know it's a small group, so any feedback is welcome. Also, if one runs 2.25" HFCs at all, please let me know what brand you bought and your impressions.

Thanks!

 

As far as I know, 2.25" cats/test pipes are supposed to provide the best power for N/A cars... Makes you wonder why so many are bigger than that.

 

Bump, anyone know of some quality 2.25" HFCs?
