Purchased both of these thinking I would have 3” all the way back. No!!!

Shop just called and said from the Kooks LT with the high flow green cats that they do not connect seamlessly at the mid pipe. Said there is the factory pinch down to 2” I gotta deal with. Only solution is custom fab from a muffler shop.

WTF!!!!

Anyone else had or heard of this issue??

I am going to the shop tomorrow to see for myself but so mad right now.

Thanks!

Yeah, that’s something to watch out for is the connection size of all connecting pipes! Ask questions and confirm the fitting all the way to the back tail pipes from the headers! Life sucks when they didn’t give the info!

The kooks has 2 different options, connect to factory with the 2 1/4 neck down or 3”
You maybe just need a pair of these in the pic.

$63 though? Better than having to pay to get it custom fabbed, for sure.

If you ordered the Kooks setup with the 3" connection there will be some modification needed for it to mate to the Corsa catback. The Corsa catback is designed to fit the stock connection point after the cats. It comes with adapters that will mate using the stock clamps. Really just depends on which headers you purchased.

Bought the 3” Kooks connection adapters and they worked great. Almost a little short but work. Crisis averted haha.
Thanks everyone!
