Ke-30 4k-u Exhaust

[tioklou]

Hello! i have a ke-30 with a 4k-u engine equipped with a weber carb! i have the 3k exhaust and i want to ask you if its good thought to keep the 3k exhaust from the exhaust manifold to the middle resonator and change the pipe after the middle resonator with a larger one (1.8"). thank you very much!!!!

if your looking at making it sound a little better and louder, then by all means do it.

If you want best power gains, would be good to chuck some extractors on and a 1 3/4 inch exhaust. would compliment that weber nicely :)

extractors would add almost no power if its a stock engine apart from the weber, but yes they would be good.

on my old system i had the 4k manifold going to a 2 inch press bents system, sounder deep and sexy once it got to about 1700 rpm
