Rad finally got sick of his super loud exhaust Revel single exit exhaust and picked up a gently used Perrin dual exit exhaust instead. This should've been an easy swap but the problem is that the Perrin exhaust flange is designed to mate to a flat flange but the JDL front pipe he has on his car has a lip on the flange designed for a donut gasket that simply wouldn't fit.

The solution was to cut off the lip with a sawzall so that we could fit a flat gasket instead.

Cutting away
Once the lip was off, it was as simple as bolting everything back together again with the new flat gasket. The new exhaust sounds amazing. I can't believe it took him this long to decide to do this.

Of course, the whole reason why we were scrambling to do this after work on a Friday afternoon was because we had autocross the next day. Despite the rain the morning, it turned out to be a great day for an autocross and we had loads of fun. I was a bit disappointed that I couldn't find more time but it felt great being out there with everyone burning rubber.
