Hey, I am buying Magnaflows for my 2002 accord v6 sedan as soon as money permits. I was thinking of buying a high-flow cat. too just to make it sound a little better and free up a bit of restirction. Is this a good idea? I know you don't want to do this on some cars, but in my case would it hurt the performance of the car?

 

you'll lose a little low-end torque. gains are minimal. i'd stick with the OEM cat unless it's gone bad.

 

Ok thanks. How can I gain low-end torque? I am getting a v2 intake, but it seems like everything on the exhaust makes it lose low end torque. Also, what causes this loss?

 

the loss is generally caused by the reduced backpressure. it seems the stock exhaust creates the perfect amount of backpressure to keep the torque where it's at.

a catback exhaust will produce enough gains on the high end to make up for the loss on the low end. i've yet to seen any sufficient gains from a hi-flow cat to really warrant changing from the oem cat.

want more low end torque? not really possible, short of completely rebuilding the block or swapping a 3.5L block.

 

ehh, thats what i figured.

 

You should check out and see if the SMSP has a universal cat for you.

I got their spunbodied with my H22, but he makes the same for the OBD2. And the price would be cheaper than others out there. Good quality stuff.

I don't know what you have done to the car, but if nothing then a highflow cat would not be the first on my list. I had to get a new cat since mine was really bad and making ratteling noises, and it spelled bad too. So I had no choice and the SMSP was much cheaper than any universal cat, or OEM for that matter. If your cat is fine then use the money towards something else. Unless you have a full exhaust and the cat is the last part to make it complete.


Hope this helps

 

I will have a cat-back exhaust, but no headers..
