If you track it, TurboXS has a setup that the cat can be switched out for a pipe pretty quick. Other than that I would say stay with one HF Cat. Especially in Cali, tickets scuk.

I like the smell of my catless exhaust, though others might not. I was trying to take a right one time on a busy street, next to a work truck with four guys in it and the windows down. I heard a loud fake-sounding cough, and looked over to see them all glaring at me.

Hey PPL,
I can't believe no-one has mentioned the other option, the 'electronic controlled divorced dumpipe'!! I have seen them advertised. Basically it's a large diameter 'Y' Pipe that attatched to your existing dump-pipe, it has a stepper motor that can either be switched or staged. So you can drive to the track with your cat, and switch the whole exhaust system off when you get there!! Most of ther ones I've seen have dumped just behind the front wheel. Looks angry, sound even angrier!! Cheers Sixpack Subaru |

Get the COBB DP It has a nice metal substrate HF cat. way in the back towards the donut gasket. Its a little stinky when cold but just fine once warmed up.

Go catless. If someone is tailing you downshift and hit them with the stink. Maybe even shoot a fireball out at the same time.

COBB's catted downpipe is great, but at $575 it's a lot more than the Helix, which I've seen for $399. I still haven't decided if it's worth the extra money.

Its not. Get the Helix. Really the only functional difference is that the COBB ends in a OEM style donut flange, whereas the Helix ends in a flat flange. The Helix would probably make a little bit more turbo noise because its bellmouth has thinner walls than COBB's cast piece (but not much). I haven't heard any bad things about either. I would have had to wait 3 months for the Helix when I was shopping for my DP, and I kinda liked the donut gasket, but thats all just personal preference.

One good thing about MadDad's catted DP is because any WG gas will pass thru non-catted, and of course.... cheaper than Cobb's. |

Results: Stink - not as bad as I thought. Definately not as bad as my 1956 willys pickup. We will wait to see if the wife and kids notice it. Sound - very little increase at idle and below 3k at about 4k it wakes up and growls more. Performance - well I haven't dyno'd it yet, however the butt dyno feels a quicker engine/throttle response and more power at the low end. I will take it to Laguna Seca next week and go for the extended WOT test and then I will probably have a final tune and dyno check done. Thanks for all the input. note: installation was uneventful until i whacked the bone right above my eye with the socket wrench handle - (insert hommer simpson sound effect and drip a little blood out) |
