neotech84 Posted October 1, 2008 Share Posted October 1, 2008 I have looked over many different choices of layouts for headers. but what works and sounds the best for a 2.5in dual exhaust??? i have seen just about every layout. the half and half 123/456 and then some do cross overs 124/356, 126/345, 146/235, ect..... i think you get the point. are there any experts here? what would the benefits of one or the other be..... or am i just worried about nothing.... thanks for the help!

Administrators BRAAP Posted October 2, 2008 Administrators Share Posted October 2, 2008 Dual 2 1/2" exhaust for an L-6?.... Is it over 5 lters displacement? Quote Link to comment Share on other sites More sharing options...
johnc Posted October 2, 2008 Share Posted October 2, 2008 You would want to do it one of two ways: 1. Alternate based on the firing order: 6 into 2 with 123 - 456. 2. Combine based on firing order: 6 into 2 with 153 - 624. I don't know which is better for performance but my guess would be the first.

Careless Posted October 5, 2008 Share Posted October 5, 2008 why not take the 2 simultaneously firing cylinders and group them into a 6-2-1 setup. it's easier to do on an L6 than it is on a v8, so you may benefit from grouping whichever cylinders fire together and have them meet so they dampen eachother out in a larger twin-collector before meeting in a tri-y connector.
