These are Doug Thorley headers for the new 5.7 V8. They are direct bolt on with no cutting or welding needed.

The maximum gain is 28 RWHP and 46 RWTQ. It really cleans up a dead spot right were you use this big engine the most.

Wow, that's not bad from only the headers alone!! Let the power mods begin

I thought the Tundra already has an "in-house" version of headers as standard equipment? And won't these new headers void the mfg warranty?

Yes they do have factory stainless tubes.
My guess would be yes on the warranty void.

Your Tundra 5.7 Already Has Headers

The Doug Thorley headers are a true Tri-Y design and there is increase flow and less restriction. According to the dyno charts, they do give a very nice increase in RWHP over stock.

+1 for the thorley headers. They are very well crafted and definitely will open up your torque..

Yes any stock manifold/header is restrictive because of design.. and about the warranty I doubt that unless something happened directly to the exhaust system thereafter the headers install. But toyota cant void a warranty for other components if it had nothing to do with the exhaust.

Keep up the good work gadget!!
later

Looks like Doug Thorley is already going to be raising the price on these.

Currently URD is selling them for $634. Next week the price will go up to $649.

You can buy them now at $634 and if you enter coupon code TN57H at check out you will get free shipping anywhere in the Continental US.

You will save a little bit on the purchase and more on shipping. It is a good deal, but act fast!!!
