Default Headers for the GS300 and GS350 from PPE Engineering

We are currently building race headers for the IS350 and will have versions for the '06 GS300 and '07+ GS350. Our IS350 headers made ~16-17WHP with a dual exhaust already installed.

We have already test fitted on an '06 GS300 and are hoping to find a local (phoenix area) GS350 for testing in the next month or so. We will be doing dyno testing on the GS300 and GS350 as soon as we can.

If there is enough interest we may do an exhaust and intake as well.

Anyone interested?

I'd be interested in the whole thing. Intake, header, and FULL exhaust. My car is in Va. and could be shipped to you if need be. It's a 09 GS350

16-17 whp??? I doubt that. Maybe 16-17 hp withe the headers,exhaust, and an intake. Post some dyno numbers to back what you guys are stating . Not trying to be an *** but its so common for manufacturers to exaggerate hp gains.

The headers will be the same price as for the IS350 headers.
Mild steel headers: $650.00
Optional High-flow cats $350.00
Optional JetHot Ceramic Coatings: $200.00 (polished), $230.00(black)

We might do the GS430 and GS460 if these go well. Not sure about the GS450h, possibly.

01a4man: if we can't find a local GS350 to test fit I will definately take you up on that.

I8ABMR: 16-17WHP are the dyno results from our prototype on the dyno at ADS in Chandler, AZ. We did not do the dyno ourselves. The car is AZ_JB's IS350, it had an F-sport intake and custom magnaflow dual exhaust before and after. The only difference was the addition of the headers (no cats). Here is AZ_JB's post with the dyno graph:

Here is our website link with pictures, dyno and video of the dyno:
http://www.ppeengineering.com/products/lexus/is350.php

We will be doing more testing when we build the rest of the exhaust.

Thanks for posting the dyno results. I remeber that my G35 sedan make 287 whp but also had an ECU retune. The 3.5 liter from Lexus responds well to air flow mods like the VQ from Nissan
