As the title says.
Is anybody running an exhaust system larger than 2.5" up to like 3" on N/A??
I have been researching exhaust sizes for ages now. 2.5" always seemed like the way to go but from what i have seen on a few forums people with b18, b20 and k20's seem to get better mid range gains with a 70mm systems. Im just worried that with me putting in a b20 or k20 with aims on 230-240 will just a decent 2.5" system do.
Just check out this DC5 dyno comaparison. going from 2.75" (70mm) buddyclub system down to 2.25" (55mm) mugen, destroys the power band across the board. He does eventually swap it out for a 2.5" (60mm) fujitsubo in the sequal video but still never gains back the difference with the 2.75" sysem.
