It's the Pypes. I feel it'll scrap and eventually leak. I have a bad exhaust leak at the moment. The ota pipes to back of mid pipe needs about an extra half inch to inch to seal. There's a small gap. The clamps are taming it some but it's still bad. Getting that fixed asap! May weld in extra pipe to the ota pipe and keep it to where I can take it off. Sounds great under some throttle but with the leak it sounds bad down low lol.

I have to get the exhaust leak fixed first. Then I'll datalog for a tune revision and take it to the rollers.

Thanks!image.jpeg
It's leaking where the clamp is located. The pipes didn't reach, there's a small gap causing a bad leak.

I remember I had this problem too. I think I pushed the whole catback forward a little bit right before the over the axles rub, but the downside is the tips were in quite a bit.

Try loosening it at the mid pipe clamp. Then push forward (towards front of car) from your axle back tips. Pop it forward with your palms. Have someone tighten it at same time. Should help.
