[Sidney]

I may purchase a stainless steel catback exhaust system from LC Engineering for $389:

but would like to know what is the stock (OEM/original) catalytic converter length as the above link says "must use 17.5" catalytic converter". I cannot go out and measure mine because it's been raining for days.
Also if I purchase LC Engineerings's stainless steel catalytic converters which flange model do I buy the 2" or 2.5"? and are their stainless cats as good as Toyotas in terms of converting gases?.Thanks.

Anyone have experience using Downey Off-Road's stainless steel cat-back # 17490-SCB for 90-95 4-Runners?:

as I am interested but what is the diameter of the flanges? are they 2" or 2.5"? and what size of catalytic converter will be required? it is a 12.5" or 17.5"?.This is for a 1995 4-Runner with 22R-E.
