At first I was contemplating on which dps to get, I couldn't decide which DP to get, my list consists of HKS, RMR, Helix, Perin, Buschur, turbo xs and etc. Then I narrowed it down to only 3" dp since I wanted more gains for my EVO. Then the price came in to play, decisions after decision, I final went with the Helix because alot of my EVO friends has helix DP~catback and they have nothing other than good things to say about their product.

Today I had my Helix DP installed, the quality and fitment is outstanding, way better than what I expected dps to be. The Helix came with MAD PIMP welds, which is damn sexy, and a 2yr warranty. The welds and the quality (Stainless steel, CNC machine mandrel bends) on the dp were top knotch. The quality and HP gains I felt was way better than my $1700 dps on my previous S4. The gains were unreal, it pulls alot harder on the top, it makes drivng so much more enjoyable. Just with a turbo-back the EVO can probably give my stage2+ S4 a good run. TO EVERYONE WHO IS LOOKING FOR A "REAL" DP GIVE THEM A TRY, YOU WILL BE HAPPY THAT YOU DID. The price is definately worth every penny I paid. Thanks to Gruppe-S and their crew of professional staffs (2 thumbs up). I'm a happy camper!!

another DP that fits excellent and is built nice is the Ultimate Racing DP.

No mod whatsoever for it to fit. The only problem that I have is that it rattles randomly every now and then. The fit and quality is awesome. I got a good deal. Very gooddd..... You'll lose a little bit on the low end, but that's like when you first install it. I think that it takes a little bit for the ECU to adjust itself to the change in back pressure. Now my evo feel stronger on the low end even. Low end = 2-3K range. But once that boost hit, it will kick you back to your seat. Mid-range torque and high end power is badass too...

What do you think of the oil pan clearance? I love my Helix DP except for that one little issue.
