Newbie here! I just looked at a blue '04 GTO this morning and fell in love and now I'm thinking about trading in. I am currently building a 427 for my TA. That motor in a new goat would be killer, but 1 3/4 headers would choke the engine quite a bit. Are 1 7/8 headers made for these cars? I can't find them anywhere. Thanks.

Mike

I imagine Stainlessworks might do it for the right price.

Sounds like a custom job to me and one killer project car.

That big a pipe may be an issue on the driver's side due to having to route the header around the steering rack. 1 & 3/4 units just skim by!

This car is a rear steer chassis meaning all steering gear is behind the wheel centerline.
