does anyone make a 1 3/4" - 2 1/2" coupling... im pretty sure the stock exhaust piping on my car is 1 3/4" maybe 1 7/8" but the inlet on my exhaust in 2.5.. i could go 1 3/4"-2" and then 2"-2 1/2" but that wouldnt look the best. has anyone seen a 1 3/4"- 2 1/2" coupling? and does anyone know the exact measurment for a 98 civic ex exhaust piping?

 

How about you get 2.5 piping installed from the cat back.

 

how about its not worth it becuase it doesnt add a whole lot of power... and this apexi exhaust was free

 

a decent muffler shop will tie everything together for $50 or less.

I sense a buzzy honda in the works.

 

what do you mean... buzzy?
