Has anyone with this cat back had any issues with a gasket wearing out where the pipe attaches to the muffler? I'm hearing what seems to be a leak in that area and I'm hoping it's just a bad gasket. The gaskets that came with the exhaust didn't seem all that substantial so I'm thinking after a year of use it finally gave out. I've been searching for higher temp gaskets bit can't find any for this specific exhaust system.
My questions are: Is this likely the issue? Has it happened to anyone else? Is it common?l for gaskets to leak after some use?
Also, if it is likely the issue, does anyone know where to get gaskets that fit the q300 that are a bit higher temp?
Car is a 2012 si coupe. Has a little "farting" noise coming from behind the rear passenger wheel right about where the muffler connects.
Thank you for your help!tweakbox appvalley https://vlc.onl/

I just replaced a gasket on mine a couple months ago, the gaskets are a known weak point on these invidia exhausts, pretty common for them to go bad. I think I bought my replacements from Vibrant (I believe they make the ones that come with the exhaust) When I get a chance I'll try to find the link I bought them from.

Edit: Here is the link for the 2 bolt gasket I had to replace.


If the leak is on the two more rearward connections than this is what you need. So if its coming from where the midpipe meets the axle back, you need this.

If the leak is at the downpipe - midpipe connection (closest to the engine) Then theres a 3 bolt gasket you'll need.
