Bought one of their 3” stainless exhausts for my 4by. It lasted 18 months before a huge crack appeared on the dump pipe. Took it into an exhaust repair shop, they welded it up but said it would crack again because it is made of very thin rubbish. I guess you get what you pay for.
Got in contact with PPD and sent them photos of the crack. They were really good about it and said they would send a new dump pipe free of charge. Just waiting for it to turn up so i can get it fitted. Hopefully it won’t be made of the same “thin rubbish”....time will tell.

Approximate cost: $599
