I did a search looking for the best high-flow cat. I am debating between the Bonez High-Flow or the Knightsports High-Flow Metallic Cat from CorkSport.

I currently have a midpipe. I would like to quiet my exhaust down some and according to my search, switching from a midpipe to a cat will yield an increase in low end torque, (with the trade off being a loss of high end horsepower. I'd actually prefer the low-end gain).

P.S. I already have a down-pipe. I plan on taking my Apex GT Racing Cat off and going with the RB Dual Tip with the cat. If it matters I have a boost controller, APEXI PFC, BNR Stage-3 Turbos, and Efini Y-pipe.

Any input on which cat would be appreciated.

 

I doubt the Knightsports cat is going to be a whole lot quieter than what you already have. If quiet is what you are looking for, the Bonez will get you better results. If performance is what you are after without a midpipe, the Knightsport would be the best choice.

 

I just bought the ATR hi flow cat I heard a lot of good things about it and the best part is that if ever it does clog up it is only 95 dollars to replace for a new one...

 

Go buy a metal core cat and have a shop weld it into your midpipe. They are less than $200 for a 3" in/out from most vendors.

 

I bought a Gotham Racing hi-flo cat, fit great good workmanship,, decent price. Check it out.
