New from Stainless Works – the Pontiac G8 headers and exhaust system. This complete system can yield up to 75 HP gains while sounding and looking great. See more details below.

Official Release:

Introducing our newest, hottest system – headers and exhaust for the Pontiac G8, with the first in the industry 2″ Primaries to a 3″ Exhaust.

Our catback system turns this classy performance sedan into an absolute monster. The mandrel-bent 3″ diameter dual exhaust features a massive X-pipe to even out cylinder pressures, and out back are a set of custom-designed turbo chambered mufflers – single-in, dual-out with polished double-wall tips. Those mufflers sound killer, and the tips look amazing!

And the headers are a piece of artwork – remember; they go on the car, not framed on the wall. The long tube design gives you a boost in low-end torque, while the individual primary tubes aid in scavenging the cylinders of exhaust gasses.

And speaking of primaries, we’ve got the largest on the market – 1-7/8-inch for the naturally aspirated rides, and huge 2-inch primaries for the supercharged crowd. Nobody else carries 2″ primaries for this beast – only Stainless Works. Get ’em while they’re hot.

Our exhaust system is amazing on this car! The Pontiac G8 showed a gain of 75 hp and 53 lb-ft of torque with our system and a dyno tune from our boys at Big 3 Racing! Let me say that again…75 freaking horses and 53 foot lbs! So get off your behind and order up a high-performance exhaust system for your Pontiac G8 today.
