This should be posted in the forced induction forum...you'll get more responses. But yes you can use any blow off you want for any car. It's all about having the right flange or connecting pipe. If you have the flange or can get one then it's able to be welded on be a local muffler shop. If you have it attached to a pipe. All you need is some couplers and your ready to go
