Aaaaahhh...I just can't get myself to go catless. I tried to lie to myself and say I'd do it, but I can't. Let me know how the smell of the gas goes gryphon. I'm so tempted to go with the Stromung two piece downpipe so that I could have one cat. I know it's only 2.5" as opposed to the HKS and Godspeed 3" DPs, but it's a sacrifice that I THINK I'm willing to make for the sake of having a cat.gryphon said:Generally speaking, for the price, it's hard to beat. I can't speak for the welds, but this is some stuff that it has going for it:
1) Replaces downpipe and midpipe
2) 75mm (~3 in.)
3) Will mate up to stock midpipe
4) Has O2 bung
5) Is SS
6) Is HKS
7) Is cheap!
Some downsides:
1) No built-in CEL fix
2) No flex joint/donut gasket provisions
3) No bellmouth/wastegate dump tube
4) Is HKS
So it's really up to you to decide what it's worth to you. I should be receiving and installing mine today. If I choose to, I will purchase some mandrel bent piping (<$50 from JCWhitney) and get a dump tube welded on (hopefully <$75 ??)
In that case, I should hopefully have a dp w/ wastegate dump tube for < $300 shipped which will mate up to the stock midpipe, which can't be beat right now.
That's cool. Surprising, but cool. My only experience with a catless car is my friends 400hp RX-7. It's obnoxiously loud, and smells like a gas truck tipped over and spilled gas all over the place. I'm glad to hear that our cars don't behave the same way under similar modificationsVerdugo said:Oh yeah the gas smell has gone away for me too...
Yeah, it definitely wasn't a leak...it was the downpipe itself. I asked the guys who tuned my unichip about it and they said there wasn't anything wrongWRXin' said:Verdugo, did you ever figure out whether that sound you were hearing was a leak?
You probably will get CEL eventually, and yes you'll need your unichip remapped for at least Stage 2 in order to work well with a completely catless system.GasolineAlley82 said:I have an HKS carbon-ti catback exhuast on my car now and i just ordered a godspeed up-pipe and an hks downpipe. Will all of these items fit together ok? Will i get a CEL and do i need my unichip remapped?![]()
