ebay 200 Cell DPs question

[castlesteve]

Anyone install ebay downpipes with 200 cell cats along with factory heat shield?

I never really considered installing DPs, but with inexpensive ones on ebay available with 200 cell cats, it's hard not to pull the trigger and give it a shot.

I would imagine fitment should be sorted out by now... the S63 has been around long enough.

To be honest I wouldn't take a chance on a cheap catted downpipe ,a hollow pipe maybe but catted I dont know ,if its a real cheap cat and it turns or breaks inside it can lead to engine damage, it can restrict the flow to much and might melt a piston on hard pulls, it happened to Autovlog on his supercharged truck blocked a path a blew the engine ,Go with AMS if want a hi flow cat ,remember its not an NA car it doesnt want back pressure ,Turbo cars want the exhaust out as fast as possible
