Catalytic converter question
Sooo.. I have been doing alot of research, and I have found that I want to go with the blitz nur spec axel backs...
My question is, I have about 227,000 miles on my car. I am pretty sure the cats have probably never been replaced..
My question is, should I jsut pull them off and hollow them out, there has got to be some way that these old cats are hindering my "great" gas mileage...
Plus I figure I can get a lil more performance from it...
Or Do they sell test pipes for it!?
Throw some opinions my way please..
As of right now the car has full stock exhaust minues axel back mufflers.

What year car do you have? 96 and up have OBD11. I replaced my main center cat. with a high flow unit. I went to a pro. shop and I new better than to ask them to delete the cat. because its illegal in In. They also installed a couple of magnaflow S.S. mufflers, very nice system.

SO I guess ur saying you don't like the blitz nurspecs?
IDk there is something about it, because I want my car to sound somewhat tuned with the exhaust.. Even tho I love a sloppy V8 nice n loud, but I want it more of a tuned sound..
Looks like he has stock cats on there still... SO if I do no cats and a magnaflow X pipe and the blitz's should sound pretty sick no?
I figure it will be slightly louder if I get rid of the primary cats...
