Im new in the forum, and im from Costa Rica, Central America, (sorry for my bad english haha)
I have a Patrol GQ 96´with TB42e, and im searching the best option of custom extractors/headers to increase power, i see 6-1 , 6-2-1 , ando 6-3-1 pipes.. a mecanic tuner friend recomend me 6-1 configuration (1-1/2" primary pipes and 3" pipe to muffler...)
any experience with that configuration? my patrol has snorkel, hi flow air filter and 3" intake pipe.. run only petrol, no gas.
I see a lot of 6-2-1 headers in ebay for TB/TD42, but no 6-1
