Default To be...or not to be... <catless that is>

Hey guys...I'm really stuck on this decision and I wanted some input.

I currently have a catback (2.5" Stromung straight midpipe to Prodrive muffler). I want to finish my exhaust setup to end up with a full turboback and catless uppipe...but I can't decide whether to go completely catless or not.

I already have gutted a stock uppipe (for stock looks/sensor mounting, factory fit, etc), and I'm currently thinking about downpipes. The Helix from Gruppe-S seems to be the best value and it's local ($325 cash with gaskets and CEL fix)...but that would leave me completely catless. I could also pick up a used MRT downpipe with cat for probably the same amount of money, but I'll have some issues fitting it to the Stromung midpipe (need adapter from MRT)

Can you guys give me some feedback on being catless? (Aside from environmental aspects) Will I get a black bumper every other day, or stink really bad? How much louder am I going to get...it's pretty quiet now. Is there really noticable power available there? Mike at SPD says that the stock downpipe isn't a restriction at all below 300hp....so I could save even more money and just get the Stromung 3rd cat eliminator for like $150.

help me out!

btw...these are dyno gains for a catless SS Turboback. mmm

I don't think that your bumper will turn black that much, but I do know that without a cat your car will smell a lot more and it will be louder. I would do it, but you gotta ask yourself if you can afford a $1500 fine if a cop catches you catless.

Is this true? I thought it was just "modified exhaust" ticket and I'd have to return it to stock and go see the smog referee guy.

Hrm...$1500 is a lot of money I could spend on this car.

Whoa! $1500 for going catless? has anyone ever been caught and had to pay that? what if you just remove one cat? do you still get a $1500 fine?

its actually a $2000+ fine. it is a federal offense, so it will be fined heavily.

as far as power is concerned... keeping only the dp cat allows for up to 300 hp before it is a restriction. same cat is used in the JDM WRX making 280 ps. and that 1 cat can mean the difference between a HUGE fine and no fine. (if the cop doesnt know the WRX has 3 cats)

Shazzam! So perhaps just eliminating the 3rd cat (along with the uppipe cat) would be a significant improvement?

That fine is surely not cool...where's Andy/BADWRX to chime in when you need him...I seem to recall he got a similar ticket a while back.

Well this is certainly discouraging me...but now I have more money to spend on other stuff!

If you've ever been to big cities where there are no laws for cats, or only recently imposed laws, I think you'd be thinking harder about the environmental issues. I'm not a tree-hugger, but I've seen Naples before they required cats in Italy, not a pretty sight. LA has nothing on a major city that doesn't require cats on cars. Give me the air quality in LA anytime over that. I think sometimes we don't realize how good we have it.

I know you said you considered the environmental issues, but really, 1 properly selected cat will not lose you that much in terms of overall power. yes, you will be giving up power, but how much. When it's debatable how much power is even gained by a catback upgrade, a cat isn't going to make a huge difference percentage-wise.

One cat is not a bad thing.

You could always run a hiflow cat downpipe. There are basically two types:

1) Replaces downpipe and 3rd cat pipe with one new pipe with one hiflow cat. The Perrin is a good example of this.

2) Replaces downpipe only with new pipe and hiflow cat. You would need a 3rd cat eliminator pipe if you want to lose the other cat. The Stromung is a good example of this.

I'm running only the stock downpipe and stock cat now. I have the Stromung 3rd cat eliminator pipe connected to my Borla. I'm installing the Stromung donwpipe with hiflow cat this weekend. This way at smog time I can put back in the stock 3rd cat pipe and at least appear to be in compliance. Plus I won't be a gross polluter. We'll see how much of a power difference the new downpipe makes.

Yup, that sounds about right. My brother got pulled over a year or so ago for a loud exhaust. The cop looked under neath to check it out, and saw his cats were removed. Paid a pretty big fine. However, he just has the cat shielding welded to the pipe....

Ok ok...so I'm becoming convinced to keep one cat. Would you keep the DP cat or the 3rd one? I would assume that a new downpipe (divorced WG or at least bellmouth) would give better gains than removing the 3rd cat.

My options now are Scoobysport DP, or Bosal DP...keeping 3rd factory cat.

Or...just lose 3rd cat with Stromung eliminator.

Option number two is much cheaper...but I don't think would yield as much power.

Hrm...thanks for the advice guys...keep it coming

two different situations. he gave you a modified exhaust fix it ticket for sound. some cops will look under your car for a cat.

I for one don't want to ever be in that situation where the cop goes hey where's your cat. I've driven without a cat before and it's not worth the stress when you see a cop. the fix it tickets are easy and cheap.

Thanks a lot guys...your advice really made sense. I'm keeping the 3rd cat, so I can point to it if a dirty-coppah wants to see it.

I just bought the twin-dump Bosal downpipe from another i-clubber. Got a sweet deal.

The final setup will be (hopefully by Sunday if the guy can fedex the downpipe):

Gutted Stock uppipe (catless) $80

Bosal twindump downpipe (catless) $220

Factory 3rd catpipe (I'm a good little hippie) $Free

Stromung straight through midpipe (no resonator) $100

Prodrive muffler $350

I think I ended up with a pretty nice full turboback system for around $750, and I can go back to "stock" by just dropping in the downpipe.

Woo hoo!
