i plan to build my motor with a lot of jdm itr ****. everything that i can get my hans on for the internal engine and outer will be jdm itr. is 2.25 big enough for this setup or should i get a 2.5 diameter exhaust. i plan to feed her a bottle when she is complete. thanks.

 

for the 1.8l motor defiantly 2.5", don't bother with the anything smaller....if its a 1.6l you can still get away with 2.25"
