I saving my money for a Helix 3" catted DP from Gruppe-s for $329 shipped!!! You can't beat that price and I've read plenty of reviews saying there high quality/sound... oh yeah, catless is $199 shipped...
my invidia was $449 shipped. But then again I bought my WRX Sept 2002 and the aftermartket wasnt what it is today
That's a great price on that uppipe. When I was ready to buy my Helix catted, only a few of the dealers actually had them in stock, so I paid more to not wait 3 weeks. I like the Helix catted bellmouth, fitment and quality of construction was great, and it's a standard bellmoth design. It also comes with an extra O2 bung that can be used for wideband tuning, and it has a real 3 inch flat flange with no reducer and donut, if you want to go full 3-inch.
man i think that you are going to like whatever you get. Im sure that you have found by now that generally you will spend more on a catted DP than you will for a non catted one. I had a non catted DP first and later changed to the helix catted. Both were good. I felt that i had a smoother powerband with the helix, but i missed that non catted sound. If i were going to do it all over again, i would go cattless and i would definately get a bellmouth!
The only advice I would give is to avoid the hks (unless they've started making a new one). It doesn't have any provisions for the wastegate like all of the others. It is cheap however.
I have it on mine and it runs great unless it's hot out but that is nothing exhaust related. My short ram intake is killing me in this heat. Anyways everyone on Nasioc likes it. There are a few that have the downpipe slightly rubbing the firewall but that is because they didn't adjust the up pipe liek they should.
Shorty dp if you want really cheap. Bosal or Stromung. They make the wastegate much more noticible. Around a $100.
I love my Invidia V2 catless bellmouth...I still don't have the cel fix light on...cross my fingers...Thanks to Michael at Sakari... Mark
