Our customer's Exige S stock exhaust came apart right after the cat while at the road course this weekend. Has this happened to anyone else before/is this a common problem? If so we'll need to find a sturdier unit. Thanks in advance for any help.

Its a Lotus...bits are SUPPOSED to fall off...:p



Did the clamp fail or break? What exactly does "came apart right after the cat" entail?

The cats are prone to cracking. I'm sure the added stress of tracking helped it along.

There have been a number of cat failures noted here on the board.

Have it replaced, or go aftermarket and save weight.

My stage 2 fell apart only after a year. It seems the internals just disintegrated

my aftermarket cat/ubend glow after hard driving (S240)... from sounds of this post, the original cat gets a lot of heat also... may be my problem is 'normal'

Very common problem, i had mine crack at the same spot. I recommend adding the forcedfed enginge dampner this will reduce engine movement. My 255 cup car exhasut has come loose four times and has melted the wheels liners . When you lose power and the exhaust pitch changes pull back into the pits.
