Unequal headers.
Could someone briefly explain the above? What difference do they make...performance / sound etc? Costs in buying, fitting???? Ta :D
|
I hear that's what give the characteristic burble? :wonder:
|
Unequal will keep burble. I fitted equal before, and only sounded like a Scooby on idle:confused:. Was told you may get diffent power curve, but personally go for un equal and keep the proper noise :thumb:
|
Equal length headers allow better flow and give better torque gains but you lose the burble and instead have a awesome noise that sounds like a motor bike when at full chat:)

It's equal headers that people most often fit as an after-market part, if they change their headers at all. |

Except for new-age JDM STIs, all scoobs come as standard with unequal headers, so your question doesn't really make a lot of sense.

port your standard headers and get a decent up pipe you will get better gains and quicker spool up unless your going for 400+ bhp dont put s/s headers on

equal length headers will give you a power increase (after mapping), but you'll loose the scooby burble - it'll sound more like an evo esp if you have a twin scroll (as per the new age jdms).
as said, port your oem unequal headers and get a trick up-pipe off Harvey for better spoll up :thumb: |
i think the equal/unequal often gets mentioned with the sports..i myself fitted some borla unequal headers to my sport to give me that much needed burble...sounds like it should do now..
