Default Installed Corsa Exhaust, Muffler Slightly Touching Diffuser

Hey guys, I spent the last few days installing the Corsa system on my C8. I wrapped it up today, and upon final check, I noticed both mufflers are slightly touching the lower diffuser/valence. They are not resting on it, just literally touching it. I went for a drive, checked the heat, etc, and it seems fine. Figured to throw a post in here and see if the consensus is to adjust it so it is not touching. Any suggestions would be appreciated.

On a side note, oh my god. The exhaust sounds incredible. If you are on the fence on a Corsa system like I was, do not hesitate. I am so glad I did it.

I have same system, you have me curious now how close mine is. There is quite a bit of adjustment in that system where you might be able to remedy that.

I have the same system and it sits on diffuser as well and over a fairly short period of time just melted that lip on the diffuser and no more contact

We've installed a bunch of them and haven't had any clearance issues - we've had to adjust/'massage' them a bit to get the fitment perfect, or close to it.

Got it. Yeah, I may need to remove the lower panels and just adjust it a bit. I don't think it needs much as it's barely touching. I thought about putting a small piece of insulation foam at the contact point but will just adjust it instead. Thanks.

Should not be resting on/touching anything. The heat will burn anything it touches.

Hey guys, so I ended up removing the panels on the underside and adjusting the exhaust. I managed to get almost half an inch of clearance. Thanks for the input. Definitely worth the extra effort to ensure things are done right.

On a side note, I do notice some water coming from the clamp areas when starting the car. I read through a few forums that it's normal, since the exhaust is not air tight unless welded together.

I still cannot believe how good the Corsa exhaust sounds. No videos I have watched have been able to capture the sound in real life. If you are on the fence, do not hesitate.
