Has anybody tried both a Perrin DW and Cobb catless Dp's? Which one performed the best? Any difference at all?

[funSTi]

I know the Cobb is overpriced. Why not get an Invidia D3 downpipe?

See, this is exactly what I mean. There are so many more affordable options, but if that's the case, why do so many people spend more than double the cost of the Invidia to get a Cobb or Perrin. Is the Divorced Wastegate design a better performer, or does the Cobb have something built into it to flow exhaust gasses better? Hahaha, just trying to figure out the best "performing" option.

I dont think there's really a difference. Before i go any further. I still have stock....I'm poor so dont take what i say to heart... Anyhow. the only difference is where the collection of gasses is...hahaha...The Cobb....from what i've seen collects all the gasses right out of the turbo once it gets to the piping it's off and out through the exhaust. With the Divorced setup the gasses from the turbo come out and from the wastegate. I guess the general idea is that gas contracts / constricts when it's cooled off. so the gas has cooled enough (3 inches from the outlet) that it'll better flow into the piping. Performance wise i dont think there is any difference but i'm a noobie and my car's still stock... I think some people pay for the name because they want the reputable companies to keep making stuff for the car.

There is no tangible difference man unless you're shooting for large whp numbers (400+). just get whatever you like/afford as long as it is a known brand.

Definetly get a divorced and catted if you are running the stocker turbo, boost creep is likely with out the kittys. Next get a AP and a protune but as far a the DP you can not go wrong with either, me I would go with the Perrin. Oh and nice pick on the color by the way.

invidia v3 (divorced catless) with a protune
i love mine

[Cr8zyJAP07]

i have invidia v2 works great. had a rubbing issue with the drain hose tho.

[04STiguy79]

Just cut the drain hose down and Zip tie it to the hole off to the left. This will allow for it to still drain and also be out of the way of being cooked to the DP.

invidia is awesome.

ive got the perrin DW catless and i love it. It looks nice, performs well, and i dont get any creep
