My 91 convertible needs a cat replacement.

Is this a simple job assuming the nuts and bolts aren't badly rusted?

Can I get the the manifold bolts with the car on jack stands, or does it need to be on a lift?

Do I need any special tools or will basic metric sockets work?

I'm looking a direct fit, one piece to replace all OEMs.

I found 2, one from Walker (Advanced Auto) and one from summitracing.com, both are about $165. Any other suggestions?

 

look on www.rx7.com they have a direct replacment by bonez. You can't buy just any old "Cat" for the rotary engine due to the higher exhaust temps and volume/flow... Do not buy a generic replacment cat or you be buying another one soon. the bonez cat will give you a little more hp also......

 

get a cat replacement pipe and a cheap generic cat

just use the cheap one on test day, otherwise use the replacement pipe

 

Thanks for ther replys. I'm a new rx7 owner and have a lot to learn.

 

I also have I question about tire size posted, it did not get any replies. Is there any advantage to using 215/60-15, instead of the stock 205/60-15

 

^traction is about the only advantage, lol
