size of Cobb dp gaskets?

[markc0220k]

ok, back to the topic.. the gasket btw dp and the cbe

 

thanks Rwebb, you are right ( and thanks for the forum here, most ppl are saying the old gasket maynot be able to be removed in one piece!) the old donut is so hard to removed, i'd tired but it was about to crack!

Glad its looking good!

You'll still need an adapter to mate the COBB downpipe to any 3" catback. You won't need it for a stock exhaust install. If I recall you'll remove the graphite donut gasket when you install the adapter and catback exhaust.

 

There are plenty of good options for around $40. I went with CNT recently and it worked great.

Is the Invidia Q300 a true 3" or does it neck down?

Pretty sure it's 3". I looked quickly on one of the vendor sites and the Invidia CBE listed the adapter as an additional item for a stock DP Edited February 12, 2020 by BoozeRS05
