197 and 200 exhausts the same??

Afternoon just wondered are the 197 bad 200 exhausts the same?? I have a 2010 200 and the exhaust is making a horrible noise when cold almost like a banging noise it clears when warmer also the middle section is blowing and I've had it repaired twice and still the same.ive looked for a 200 standard system but can't find one anywhere but am seeing lots of 197 ones.just to add think it's had a cat removed to.it did pass last mot tho.
Thanks Graeme.
