Is 80mm to big

I was looking at the rs-r exmag catback system and noticed it was 80mm. I like the rs-r because its quiet but is 80mm to big on a NA motor?

There's really nothing wrong with getting a 3 inch exhaust for NA. It is just that you lose more low end tourque because you lose backpressure. It is recommended to get 2.5 inches or less for NA.

My boy Chronic has it on his 93 coupe and he loves it.

You wouldn't know it was in there when he has his silencer in.

Yea, it hurts the low end torque. But not dramatically. 2.5" woudl be better for the N/A, but 3" aint bad
