As the title.
Does anybody have a Cobra track day cat back fitted?

I want to know how loud it is, and is it intrusive in the car and does it drone at motorway speeds?

Thanks

I have a full decat turbo back and it does boom on the motorway (I dont do big miles so no problem).
I think you can get away with any cat back just fine as I think its the mid section that makes the bigger difference once replaced.

I've got a miltek back box at the moment with a cobra Decat down pipe and resonated centre.
I Think it's still to loud.

Is this the system you have?

Apologies no, I doubt mine would be track friendly, was just saying for comparison that its really the mid section that when larger and non resonated, booms quite a bit compared to a backbox alone. A resonator would certainly bring the noise down a touch.
This is my system, TP64 rear exit (4.5")

I previously had an angled cobra rear box and it was possibly louder, set car alarms off more often . The quietest box I had was a Mongoose though it was just a cat back.
