The Dyno result is impressive. I also like the 321SS you used to make the exhaust. The problem is, how would you sell me when I m already having GMG header, 200cel cat and rear bypass. lol
You do what I'm going to do and sell your GMG bypass and headers. Actually please pm me if you're interested in purchasing. I need to let these go before the RK Dundon set up arrives . The results on the GMG set up have been discussed in detail on the forums.
Keep your stock center muffler, no drone, quiet around town and get 40whp and 30wtq gains!
This is by far the best results we could have hoped for. No need for a flash tune with this, you will see gains everywhere with bolt ons only and keep the car quiet around town!
991 GT3 Dundon Motorsport Headers with Stock Muffler connector pipes!
I have videos in the car as well that I'll post up.
[QUOTE=qbix;13111663]You are saying 40-55WHP and no CEL...
What about this video:
Go to 1:25. Even start. Cars pull exactly the same.
Matt also mentioned in one of his posts that he got CEL...
Any other real world comparisons available?[/]
Up to you to believe repeated dyno results or not...
Matt himself said to ignore these videos for any reasonable comparisons. Need to run up to 3-4 gear at speeds well higher than any sane person should do on the street to see the differences. As track season comes to life for most of the country and more folks get their headers installed we'll see more "real world" data. As far as the CEL, Matt did get a CEL, and it went out on its own, and it was never scanned to see the what it was for. The 991 GT3 sets a CEL for a multitude of things, at this point we don't know what it was for. Typically emissions related CEL's don't go out on their own...
Matt is going to join a number of other GT3's in the Smokey Mountains and There is an airstrip event scheduled.
We'll try to get some vbox times established as well.
