Ebay dump pipes

[VIN18M]

Has anyone purchased one of the no name stainless steel ebay dump pipes?

Would the stainless steel not crack over time?

Any feedback?

i put one in not long ago got it from demon motorsport, was definately not best quality i had to grind it on the inside abit and the gaskets were shit but there are definate improvements over the standard

Why did it need to be grinded on the inside? Welding dags? or just badly finished? Did it match up to the exhaust housing well?

there was about 10-15 mm of metal on the bottom of the wastegate exit that i had to grind flat, it meets up and sits good on the housing except the wastegate exit is shaped differently and it covers a small amount. i'll prob try find someone to make one down the track when i get more serious about the tune.

I'll add that these dont flow as much as the cast dumps and cast is better for heat and more reliable.
