LSter94 Posted July 9, 2002 Share Posted July 9, 2002 What is the difference between headers, every company makes different styles. Is a one piece better than a two, is 4-1 better than 4-2-1? Anyone know? Link to comment Share on other sites More sharing options...
meguel24 Posted July 9, 2002 Share Posted July 9, 2002 I have the 4-1 one piece ceramic DC Sports, pleased with it. http://www.dcsports.com/41.html http://www.dcsports.com/421.html Link to comment Share on other sites More sharing options...
Sonik Posted October 14, 2002 Share Posted October 14, 2002 As far as to which header of choice this may help you out. It will all depend on where you want the added power. For High Range Power go with the 4-1 header. You will notice most when your VTEC kicks in. If you want to have more low to mid range power go with the 4-2-1. This was my choice since I am very confident with the power band once VTEC kicks in and I wanted some more low end power. I have the DC Sports Ceramic 4-2-1 and I am happy with it. But...remember this, if you plan to go Turbo in the future and you still decide to purchase the header now, know that you will no longer be using your aftermarket header once you move to Turbo. Just my two cents. L8 Link to comment Share on other sites More sharing options...
EGRacer Posted October 14, 2002 Share Posted October 14, 2002 4-1 is nice and sounds deeper and is more for top end. 4-2-1 is awesome and sounds even deeper and produces more torque than anything else Link to comment Share on other sites More sharing options...
Toda Party Posted October 18, 2002 Share Posted October 18, 2002 i dont really buy into the whole 4-1 = top end 4-2-1 = mid range talk. Why? Toda racing and SMSP, two of the best flowing honda aftermarket headers are of a 4-2-1 design. I think it has much more to do with tubing diameters, quality of the welds and merges of the tubing, and COLLECTOR sizes rather than the basic 4-1 or 4-2-1 designs. these are stock graphs (stock internals, i think it had an exhaust and intake) DC JDM is a 4-1 design with 2.5" collector. Type1 is a 4-2-1 design with a 2.5" collector. Type 1 Vs Toda 4-2-1... more graphs here: http://www.automotiveperformanceengineerin...com/header.html SMSP 4-2-1 Peak Numbers (don't mean much but for the sake of argument..) Toda 4-2-1: 190/137 Type 1 4-2-1: 186/137 DC JDM 4-1: 187/137 SMSP 4-2-1: 190/136 So what am I trying to say? IMO, i don't think that 4-2-1 and 4-1 designs make any kind of real difference... 4-2-1's put out more peak hp and tq than 4-1's did, and there was no discernible loss in the low or mid-range..

EGRacer Posted October 18, 2002 Share Posted October 18, 2002 well not to be rude but thats the way it was with mine. i had a mugen 4-1 straight through with a custom after cat exhaust and a high flow cat. i was getting way top end but when i got my 4-2-1 header i had lots more torque than normal cause i could stick it in first and floor it and smoke the tires. i couldnt do that w/ the 4-1 Link to comment Share on other sites More sharing options...
Toda Party Posted November 1, 2002 Share Posted November 1, 2002 So because u could smoke ur tires with one header, and you couldn't with another....that's how you derive that 4-2-1 puts out more torque? You should be able to smoke ur tires bone stock. Post dyno numbers. Otherwise, im right, you're wrong. Link to comment Share on other sites More sharing options...
