I'm looking at the summitt catalog to find a replacement for RB turbo presilencer

which length and diameter cat should i get??

they have 10", 12", 13", 16", 21"
i guess the closer to the actual length, the less i'll have to pay the professional for material and welding

diameter should be 3in right?

Also which brand do you guys recommend?
Catco, dynamax, magnaflow?

 

21" and get the cheapest one, put it on before you test, take your car for atleast a one hour drive and test while the thing is nice and HOTT, but as confered with my friend and he suggested the cheapest one that can withstand rotary heat, your best bet would be a Bonez highflow

 

I bought the 3" Bonez Highflow and 2 RB 3" flanges, and had it custom fit to the RB turbo back Exhaust. I asked RB the question of how long the presilencer section is and this is the response i got.

"The length is approximately 29" overall. Since the flanges are not parallel with each other, coming up with an "exact" measurement is difficult. This should give you the starting point in obtaining a cat for your system.
