My ZZP 2.5 catless downpipe fell apart less than a year of being on the car.

I'm going with a random tech downpipe now.

the flex is cause when ur s.s gets hot it exspands and when the car is off it will shrink so when the put the flex in our exhaust they needed to put that in so the exhaust can move with the motor and we should all be glad that gmpd put the braid on it cause if they didnt our flex would grow so much its not funny get motor mounts ur flex wont look like that anymore

not disagreeing, but the exhaust temps are much higher than 300 degrees... about four times that much.
