[driftking777]

ok...anywho...i just went to an exhaust place to see how much some stainless steel exhaust would cost from the flex hose back...came to about 175 that with them welding on my Apexi N1 muffer...anywho...i want to get a high flow cat also...where can i get one...and what brand is it...has anyone tried it....i own the car in my sig...so try to be 5th gen specific...5sfe motor.

Catco makes them. You can usually pick them up on ebay for 40 or 50 bucks. Summit racing has them also. If you get a universal one, which you might have to because I doubt they have one thats celica specific, go out and measure the size of your pipes and also the length of the cat. If you are getting all new exhaust then the place should be able to accomodate for a shorter or longer one.

I think its a great mod to add with a high flow exhaust!! Theres a few other companies that make them but im drawing a blank right now. Check out summitracing.com or jegs im sure they sell more than one brand.

well just to make sure im not just stupid here but...is all your cats right from you exhaust manifold...because i went to an exhuast place that going to be doing my stainless 2.5" exhaust and he said that they cant replace that cat with a high flow becuase they dont make them...enlighten me.

Im not sure what your trying to ask but the cats are usually located down from the exhaust manifold a bit. On my car they are under the passengers feet but thats because I have a y pipe and its a little longer.

There should be no reason though why they cant accomodate a high flow cat to fit. You just need to make sure you get the right sized one and if its a little longer they should just be able to shorten the exhaust pipes they are going to install.

cat back means everything from the catalytic converter back... theres 5 pieces to ur exhaust...

exhaust manifold, then downpipe/aka flexpipe, then cat, then exhaust pipe, then muffler, catback is everything from the catalytic converter to muffler
