I would like some recommendations for a DP. I originally was just going to keep my HF cat and get a bung put on it for my WB but I have a little extra money and figured a downpipe would be nice as well and then saves a little hassle as well.

A little about AKINA , she is a daily driver I don't track her, although my friend wants me to start going but I know I will be hooked if I do. She basically now just has fun on the parkway making the commute much more enjoyable. Yes, the LEFT LANE is Mine, PLEASE STAY IN THE RIGHT!

I am thinking of an AMS widemouth downpipe, but maybe the MAP. But any suggestions of what might be better.

She is still stock Turbo ( for now I plan on upgrading later but not it the immediate future), ETS HF Cat, Invidia Q300 exhaust, K&N intake and UICP).

Recommendations please. Thanks

If your going to stay stock framed turbo then both are good. If you think you could go with a turbo kit in the future. Then just save your money as the kit will come with one.

I might go for a FP RED or the GARRETT GT3076R kit later down the road but neither include a DP. We are talking much later down the road, most likely a year or year and a half and I need to get my wideband installed so this will eliminate me getting a bung put in the HF cat.

I am very happy with the MAP o2 elim downpipe on my car. It dyno-tested solid gains even on the stock turbo.

Ultimate racing 02 elim, ETS 02 elim, map 02 elim .. those are the 3 most popular and all have shown gains on the stock turbo as well as upgraded stock frame turbo's.

Yup, all three of those are very similar in design and I'd expect the results to be near identical.

Here is my dyno-testing: https://www.evolutionm.net/forums/ev...ven-gains.html

Has anyone eliminated the cat and kept the stock exhaust? I assume all these downpipes will sound similarly, just curious on the effects of downpipe w/o exhaust.

<somewhat offtopic>
I want a quiet car, but I would imagine eliminating your cat is the #1 thing you can do aside from a tune. My Sky is LOUD after all the mods, and I'm fine with that, but this one is a daily driver whereas the Sky is a dry-roads only car.

There are plenty of very good and fairly quiet catback options on the market:

-Cobb
-Magnaflow
-Buschur Crossflow
-ETS Quiet Edition

...just to name a few. If noise is also a serious concern look into using a HFC rather than a testpipe.

Man you are on top of things! As I continue to take this thread offtopic (Sorry OP), what are the differences in gains between the HFC and full delete?

Pimplay2

i had test pipe w/stock exhaust for a little while it doesnt change the soud, car is still quiet, the stock muffler baffles ALL sound

Pimplay2

full delete=quicker turbo response + gas smell

hfc= still decently faster response over stock - gas smell

As just a rough guess on the stock turbo I'm going to say 10whp, but again, that's just a rough guess and will be dependent on your setup and tuner.

Can't go wrong with any of your choices... Like kracka I also have and suggest map dp. Can't beat it for the price. Call Adam at map for good price on whatever u decide on.
