two and a half inch

 

yup 2.5" would do it

 

u think 2.25 is too small for this?

 

Personally Id run 2.25, but I often have been called loony for going against the grain....Ive found in many N/A applications...unless you have serious amounts of work done...and are pushing serious time slips.....2.5 is to free flowing, reduces actual back pressure....but thats just my opinion, its not the gospel....the other two guys who responded are not wrong.....its all in your school of thought

 

i dont think hes really concerned with low end tourque, isnt that what backpressure is best for? not flaming, just inquiring?
