Which one to choose and why? AMS widemouth, ETS recirc or Tomei expreme. AMS looks really nice.Also how to install heat shield to ETS, no bolt holes. Car has stock with panel filter, 3 exhaust , planned to do dyno and flash and 300whp.
Is it worth or pointless mod for stock car?

I have an AMS downpipe and would recommend it to anyone in the market.

If you aren't worried about the volume of your car a o2 dump downpipe will work the best for you.
MAP makes a great one (I own the Recirc Version because it is much quieter) Link for the one I own:

and ETS also Makes fantastic ones. (a large amount more money than MAP)

I would say it is a great mod for a stock car!

I would choose our recirculated downpipe. The reason being that we separate the wastegate gasses from the exhaust gasses which gives us a free flowing exhaust stream while the wastegate is opening and closing during wide open throttle (Between shifts) and partial throttle. This prevents excess turbulence in your exhaust stream. We then reintroduce the exhaust gasses down stream when they have an established flow pattern. See the diagram below.

Also our downpipe comes with a gasket, a lot of the aftermarket options do not come with a gasket. We also have a profiled flange which matches the turbocharger outlet.





Thanks!

Perrin dp is not worth the money and that is my opinion. ~ $550

I bought the MAP 02 dump downpipe, so I can't really comment on OP's request between his choices, but I can say that I did the install myself and it was easy up until the last bolt broke inside of the turbo flange =_=.... The install definitely sucks though, be prepared for anything to happen and make sure you spray all your bolts with penetrating solution a suggested day before you do the install. It will make your life so much easier haha. But I will say super to the MAP 02 dump. Just from what I've heard, open dump makes much more power than the recirc downpipes. Getting tuned this weekend so we shall see

If you get ETS get it coated will solve you heat shield issue.
