I have an 04' WRX with Prodrive Intake and SPT Cat Back.

I am looking to add a Down Pipe here soon. And get the Snowmann Tuning!!!

I want to get some advice on Down Pipes.

Right now I am looking at the Invidia WRX STI V3 Divorced Wastegate Downpipe Catless, but I am not sure if running catless is ok.

Also some people have told me that I cant run a DP on an 04 WRX with out Full EM (due to OL/CL problems).

Also whats with the divorced wastegate?

Any and all information would help a lot. I am new to the whole DP topic!!

Thanks,

Mike
