I'll be asking a shop here in our place to fabricate headers similar to the weapon R race headers for my GD3. Would anyone know the optimal dimensions (Inside Diameter) for the pipes and the collector? I have a Fujitsubo Powergetter Catback with 2.25" ID.

Thanks!

 

I've already had a custom made header and i've made it smaller than the weapon R race header. 1.5" runners and 2" collector. The fujitsubo power getter sounds way better now after the headers and cat delete. I'll have it tuned in the weekend.

 

That sounds pretty neat. Could you share some photos?

 

They are asking for info. Nothing has been built. smh

 

His second post sounds a lot like he had a header made.

 

Recycled the O2 bungs from the stock headers/downpipe.

 

Here are the only pics that I have at the moment.

 

Soundclip here.

Current setup is AEM Cold Air Intake + 4-2-1 Headers(Cat Delete) + Fujitsubo Powergetter
