Hi Craig. It is difficult with all GM's 06 and above to put a very high flow cat on and keep the engine light off. We have been able to accomplish this with the N/A and the GXP. We struggled long and hard at this with a lot of help from some high level engineers and converter people. On the GXP the fix had to do with the O2 repositioning in the front pipe and a special O2 extender. With the N/A we just need the extender. We're happy to say that many converters later the "lights are still out." We were unable to make it to the Ottawa run. I heard it was a lot of fun. I'm sure you met Iggy, Jack, Shabby or Grey Ghost from our area. Very nice guys. Thanks Norm and Spiky!!
Norm,
I was looking through your site. With your huge line-up, a choice isn't particularily easy. It's nice to see a company that knows what looks good.
Spikey,
Thnks. It appears that Solo's hard work has paid off.
Goingsolo,
I really appreciate the response. I met some one that pressure tested systems for GM. I dunno? I have been mistaken before. It could have been Jack? A great bunch nonetheless. I enjoyed the cruise.
I stopped working directly with GM aftermarket products around 04, so I have much to learn if I intend on playing with my toy.
Craig,
I have a Hahn High-flow cat, with a tune. Never had a code until I jumped on it one day and a "check engine" code appeared. A few days later it dissappeared. It happened again once after that. After I had the ECM retuned for a turbocharger they made adjustments so the code didn't show up.
Yeah, It does happen. The dealer said the first time I took it in not to get concerned over the code unless the light begins flashing.
Yonnie,
Your dealer is a rare breed. I am amazed they would take your car in with an aftermarket turbo. Mosty dealers I know would go crosseyed and blow smoke out the ears.
