So recently I bought a MAP performance open downpipe and once i was about to install it. I was told that the downpipe would be bad for my car cause I have the stock wastegate.

Mod list:
-GS EBC
-Cobb sf intake with cobb turbo inlet
-full exhaust with test pipe
-turbo smart bov
-Cobb v3

What does that have to do with anything? I mean sure stock wastegates are going to open early. Unless the downpipe doesn't fit with the map downpipe.

We call that a screamer pipe in Australia. Vents wastegate to atmosphere making a heck of a lot more noise.

Nothing wrong with it, if its a dd I probably wouldn't do it myself, but each to their own

I think this is what you are talking about;

Disregard what you're concern is. Put it on and have fun. It's only loud and wot and, since you own an evo, I assume you'll enjoy the sound.

I had the ets one, loved it and going to do it again on my 15'

I have the MAP open dump on my 11' and I daily it in the summer with no issues but without a doubt it is very loud. The one time it can get annoying is on the highway because its hard to accelerate without opening it.
