Pulling my old buddy's
My Kook's 1 3/4 are off and Sending them to another member to enjoy. 1 7/8's AR's from A&A Corvette are coming.
I will say the KooK's really did me well. They install like a glove,
I had a really nice increase from them 372-420's hp. Plus the power comes like gang busters from 3000 on perfect for what I wanted at the time. But after being on the phone with a couple of tuners. One witnessed a 45rwtq
gain from 1 3/4 to 1 7/8's on a S/C'd c-6. Then the big gain Vette Doctors saw from 1 3/4 to 1 7/8's. Comfirms that 1 7/8 help over the 500 rwhp mark. Below that I feel the 1 3/4's do better. I went with the AR"s
this time as I feel that the more rear placement is better with respect to the cats. For S/c'd Cars. Non s/c'd I like the Kook's
as the temps the cats see should be a little lower. The S/c really pumps
the exhaust heat under boost sounding like your sitting on a Jet turbine.
Also I am going to full 3 inch from 2 1/2.
before and after dyno's coming soon.
