Hi Danny,

Your Berk test pipes should have come with a pair of graphite gaskets. They would go between the header/TP flange. It's possible that we forgot them but they are taped on one of the flaps of the box and they often get missed. Just let us know and we'll make it right!

Going to PM you.

my test pipes from berk came with them. theyre taped to the upper flap of the box. did ur service engine soon light come on with the pipes?

Ya took about ~100 miles and then it came on when I was just cruising down the highway.

mine too. I went to my dealership yesterday when i got my oil changed, and they used that OBDII thing and got rid of it. So, I dont know how long it will last. I've only put 20 miles since yesterday, but ima be putting 230 today...we'll see what happens. overall, i was very pleased with the results. do u get that rasp around 2600-2900rpms too? and does it make that hiss noise when ur decelerating? I dont even mind it anymore.

That "just under 3k" rasp and the hiss on decel (really, you can get the hiss at steady state too) are the sound issues that were worrying me as well. I now have confirmed I have an exhaust leak (I messed up a gasket from all the playing with fitment issues), so that may be the culprit. Waiting on gaskets now.

SSQ you gotta let me hear your car, you probably have a leak.
