Klank Posted February 16, 2010 Share Posted February 16, 2010 Good morning, all. Firstly, I apologise for such an unsophisticated technical query, but I'm having a bit of chew finding the correct ones. I've had a good search but can't find the answer I'm looking for. I've fitted a Kakimoto Racing cat-back to my N/A which still has the second cat fitted. I used the old compression ring and got a very tight seal to the cat, which isn't blowing. My problem is the gasket between the centre pipe and backbox. I cleaned up the flanges and measured the bore of the pipe, but it's closer to 2 3/4". I got some gaskets off eBay suitable for 2 1/2" which were inevitably a bit too small. Are the standard flanges 3" on the N/A? I snipped the edges off the 2 1/2" gasket just to get me away, but it's not getting a good seal and blows a fair bit. I'm expecting to hear, "get the 3" gasket off eBay, you numpty!" But any info would be appreciated. Regards, Keith. Link to comment Share on other sites More sharing options...

Klank Posted February 17, 2010 Author Share Posted February 17, 2010 Thanks for the input, Nic. I would go to a dealer, but I'm not after the compression rings, I need one of the standard metal gaskets, such as this one. I just need to know if the bolt centres are correct. Rgds, Keith.

merckx Posted February 17, 2010 Share Posted February 17, 2010 Exhaust assembly paste will do the job, just make sure you use enough. Link to comment Share on other sites More sharing options...
