ok i'm gonna get a mugen header with a apex n1 exhaust. If i get the header with a 2.5 collector and the exhaust is 2.25 will that make a difference? It's that i can get a really good deal on a JDM mugen header with a 2.5 collector

i already have the DC 4-2-1 and i'm not very happy with it. Since i'm staying all motor i wanna get the most power i can from every part. I'm sorry but i'm not asking you guys if i should get 4-2-1 or 4-1. I'm not even asking which header to get. I'm just asking if i get a header with a 2.5 collector and a exhaust with a 2.25 piping will it matter.

The bottle neck will be the diameter of the piping at its smallest point. Why get a 2.5 header if you have 2.25 piping? If you plan on upgrading the exhaust later then go for it. If not... ah your gonna do it anyway so who cares?

i'm just looking for some advice. Is it better to get a 2.5 header with a 2.5 exhaust or a 2.25 header with a 2.25 exhaust?

if u getting a 2.5 collector get a 2.5 exhaust right no my headers are 2.25 and exhaust is 2.5 heh im going turbo soon so it dosent matter

i just wanna know what makes more power 2.5 or 2.25. I'm staying all motor. I would think 2.5 would make more power cause it's more free flowing. What do you guys think. I would like to buy a header and exhaust today

2.5 all the way you'll get more power out of it than the 2.25

Buy the 2.5... bigger is better
