Seriously, your existing MOD's have nothing to do with a Good Performance Cat.
And people ONLY buy "quality stuff" ONLY get Robbed a Lot.

think about this
Do you want to go lets call it a "tiny bit street illegal"
the best Gain you can get out of a Cat, is to Jam a Paddle Drill Bit down your Existing Cat. Meaning you have no Cat at all.

If you have to take emmissions very often, and do not want to go to a junk yard, and invest in a swap cat for those times, then you don't want to do that.

But that's what i"m going do , when i get off my lazy @$$.

Second, do you want to PAY for a STAINLESS STEEL finish on a part of the car, that no one but your Repair Mechanic will ever see.

yeah me neither,

OBX is a decent affordable Brand. However, a Catalytic converter is not a Complicated Thing, with moving parts, and High Quality grade 5 steal and BLAH BLAH BLAH ... A Catalytic converter is a Peice of Pipe, with a Honey Comb of Ceramic inside of it, A monkey could make one. Its heavy and very exhaust restricting.
Racing Cats, are simply a Piece of pipe, with a ceramic honey comb in it, cept the holes in the ceramic are a little bigger, letting a little more air through. Point Being, you get as much gain out of a decent $50 Cat as a $199 Name brand Cat.

just my 2 cents
