Like the title says, whats the best catalytic converter for a N/A? I'm trying to save money but still have a good exhaust system. I already decided on 6" round offset magnaflow mufflers http://www.magnaflow.com/02product/s...ne=main&id=518 these 3" tips http://www.magnaflow.com/02product/s...ne=main&id=671 and a racingbeat header. Now I need a cat so far I'm looking at Bonez, Magnaflow, or a Random Technology catalytic converter. I'm looking for one that will last and flow good. What do you guys think?

thanks

 

I'm pretty happy with my bonez superflo, sounds good and smooth.

 

Ive got a bonez strait pipe and i love it

 

If "living in a box" requires no emissions testing, then just run a straight pipe.

Other than that, a lot of people on here have had success with the Bonez high-flow cat.

 

Yup, like the Bonez cat (Superflo system) that I'm selling .

 

Nope, I've got emissions. I'm trying to find the best flowing and longest lasting cat I can get, And if the Bonez superflo gives me that then thats what I want.

 

no cat is best cat

 

run straight pipes and re-install the cat when you have to SMOG the car. Can't get simpler than that.

 

I also use the Bonez system and it sounds excellent. (Why do people have to keep saying just take it out...he ASKED for a cat c'mon guys be serious)

I haven't really heard anything bad about any cat for the FC, but I do believe that most are prolly using the Bonez system (it was pretty much the only thing around really for a while from what I remember). Nice deep and smooth, yet not artificial sound and it's good for power as well (butt dyno test only).

Racing Beat pre-silencer.

 

I went with a Magna flow cat with an air tap on my s5 and it works well ive only had it 3 months but it helped me pass emissions, and even mellowed out the tone of my exhaust. Im running a racing beat header (2.5"), piece of 2.5" pipe to the cat to factory y pipe and factory muffler, sounds a little raspy but everyone seems to really like it. When I can find a deal on a second hand racing beat cat back thats what i plan to do.

 

What, model did you use? They have a 9400 model with an air tube, but I think it is made for V8s or 7000lb trucks.

 

I had the Random Technology cat setup about 6 years ago (RB header, HKS catback) and 2 months after installation it was done. Got a free replacement and ditto. Spirited driving or not, they sucked IMO. I now am installing a Bonez cat in my new setup. Not completed yet because RP neglected to send me the header gasket with the rest of the exhaust system. Damn them!

 

u can get header gaskets from advance auto or the mazda dealer. Its the same...
