Unleashed! This is what these catalytic converters do to the Pontiac G8. The exhaust note becomes “RAW” with a huge burble on decal. The best part is that there is no drone with any of our exhaust kits. We were surprised to see that Pontiac had decreased the internal size of their catalytic converters to 1 ¾” on the inlet side. We suspect that they did this for sound control. Our catalytic converters are a full 2 ½”, we use a heave duty flex pipe and laser cut stainless steel flanges along with our stainless steel pipes.
Thanks so much to NightWing, Zepcom, and JEC G8GT for the use of their cars during our initial test and design phase. Nightwing had to constantly give up his car during three different test manufacturers and multiple O2 bung placements. All of the initial testing is complete and we are very happy to say that there is over 500 miles on each vehicle and no engine light has come on.
GM’s OBDII design is very tricky and we are committed to some further testing before we can say that we have the engine light problem solved for sure. We would like to have up to 15 “Beta” test vehicles to further test these catalytic converters. If 15 more cars have the converters put on with no CEL (check engine light) issues we will be confidant in telling potential customers that they won’t have any trouble.
We have our manufacturer making a special run of these “200 cell” stainless steel wound catalytic converters for us. We have these catalytic converters far overrated for this car and this additional “spray” (the catalyst rare metals) is what helps to keep the engine light off. We also have to use an oxygen sensor extender in the two rear O2 ports. The extender is a Solo designed product and is the final puzzle piece to keeping the engine light off.
Much testing was done to ensure that we were able to combat the engine light problem. We appreciate your patience and understanding during this phase. We know that many may not like the idea that only 15 will be released for further testing. This is being done to allow us the opportunity to “fix” any issues that may come up once they are on more peoples vehicles. We thank you in advance for your understanding.
Note: Works perfectly with most aftermarket tunes (VMS, Livernois, etc.) to date. The only tune that has had a few isolated issues is the Superchips/Cortex (same thing). A tune is NOT required to run these cats.
