GS400 Headers

Anyone know if the GS400 headers are less restrictive than the ones on the early SC400s. I am looking to mod my car up some more and would rather have a toyota part on there than have a fabrication made.

Also, what is the part number and cost of the headers.

Thx!!!

I don't have headers on my GS400 (2000 model), I'm looking for a company that makes headers for GS's...

Are you talking about the exhaust manifold (stock)?

As far as I know no company makes headers for our cars, but a local shop here in Hawaii said that they could manufacture some for me but it would cost me some scrips...

Headers should give some improvement. I would be interested dependant on the price.

Didn't Leo from WeaponR try to make some headers for GS4 but it seemed that no many interests due to the price? Personally speaking, I won't spend $1000 for 10hp gain.

10HP!!! I bet you headers on a 400 would give way more HP.
Acura TL Type-s' were dynoing close to 30HP gains at the wheels.
Reg TL's gained around 18HP at the wheels.
Headers on my old mustang 5.0 gained about 11HP at the wheels.
