Has anyone had expiernce with the Bonez high flow cat? Is it worth the $, does it actualy flow alot better or a waste of money? I was just thinking of getting the mid pipe and putting the stock cats back in for e-check. Anyone had expiernce with bonez sistym and how easy it is to install? thanks

its a good cat....sounds alil deeper and louder....helps out the rev and high speed....

 

Get the mid pipe. more power and less money.

 

I have one, Im not using. I went to a header, this replaces the cats.

 

I installed the Bonez DP and Cat at the same time. Construction and fit were good and I thought the price was good from Rotary Performance. Sounds louder and deeper than stock from outside; not bad at all inside.

You need to do something about heat shielding if you take off the stock Cat section and put in an aftermarket one. Either get the Bonez pieces jetcoated or salvage and re-install the heat shields from your stock cat section. Otherwise, your tranny tunnel and center console will get very hot in spirited driving. Voice of experience here.

I have no dyno figures before/after. The turbos spool MUCH quicker than they did before and my butt-dyno says there's more power.

I have not tried to pass an emission test with the Bonez cat. I have the air pump hooked up and there's no backfiring when I go off-throttle after WOT, so the cat is doing its job. It should be sufficient for you to pass an emission test.
