My car passes emissions now w/o cats but i'm sure they will start sniffing soon. So your 50 state cat system will cover me in the event my state starts sniffing the tail pipes?
In order to pass emissions, you'll have to install the cat-back version of the system onto the outlets of your factory catalytic converters; there is no other emissions legal configuration.
So... your true duel Black hart system(mid headers and true duels tubes) will not do this w/o me cutting the pipes and installing some form of cat,is this correct??
I might be asking the same question but before I sink 1800 bucks I would like to be very sure what im getting/not getting.

Ok....I'm back. I've been looking and reading about your BH ststem. I was not understanding what you were telling me,now i do. You have a long tube header that connects to your true duel exhaust. How far does the LT's hang down under the car,any tighter then some other brands or about the same? I have SLP with a hacked hanging Y pipe that hits most speed bumps,so at this point anything else will be a move in the right direction.
I guess the system is a hit ha??

There is a race version of the dual system, which connects to the mid-length headers, and the cat-back system version that connects to the outlets of the stock cats. The cat-back system is the only one the provides for legal street operation of your vehicle by the letter of the law...you cannot legally remove properly functioning OE cats from your car.

Rules for Replacing Converters
In 1986, the U.S. Environmental Protection Agency issued new guidelines for the construction, efficiency and installation of aftermarket catalytic converters. All CleanAir converters listed in this catalog have been designed, tested and manufactured to meet this policy.
In addition, CleanAir converter listed in this catalog is appropriate for use under the current requirements of the California Air Resources Board (C.A.R.B.).
E.P.A. guidelines state that replacement converters may be installed only in the following situations:
1. The vehicle is missing a converter
2. A state or local inspection program has determined that the existing converter needs replacement
3. Vehicles manufactured prior to 1996 must have more than 50,000 miles, and a legitimate need for replacement must be established and documented
4. In cases of OBD Il-equipped vehicles (1996 and later), the O.E. manufacturer's 8-year/80,000-mile warranty must have expired and a legitimate need for replacement must be established and documented.
Please note that Federal law prohibits removal or replacement of a properly functioning O.E. converter.
When replacement of the converter is appropriate (as outlined above), the E.P.A. further requires that:
1. It be installed in the same location as the original
2. It be the same type as the original (i.e., two-way, three-way, three-way plus air/three-way plus oxidation)
3. It be the proper model for the vehicle application as determined and specified by the manufacturer
4. It be properly connected to any existing air injection components on the vehicle
5. It be installed with any other required converter for a particular application
6. It be accompanied by a warranty information card to be completed by the installer.

Yes, there are federal and state laws that make it absolutely illegal to remove a properly functioning catalytic converter. There is no gray area within the law to make it open to interpretation.

EVERY longtube on the market except the original slp design tucks up the same. EVERY longtube on the market is tucked so high that if you run a straight pipe off of the driver header, the pipe will be rubbing the underside of the car. This is why connector pipes off teh driver side either have a flat spot pre fabbed into them or they dip down to clear that floor brace under the car because EVERY longtube on the market is tucked so high.

The mid length header may dump higher than a longtube but the connection pipe is still gonna be in the same spot. The only ground clearance advantage to the Blackheart system is due to it being 2.5" pipe. As I keep saying all headers on the market have the collectors so high that a straight pipe off of them would be rubbing the floor brace

Haven't checked this thread in a while. Cool to see you guys developing a LT friendly setup for your exhaust. Was considering getting my LM1 cat back re-welded and adapted for the longer TSP y-pipe so I can have a full exhaust out the back. I'll have to keep an eye on this thread a little closer now.

Hooker does crimp the pipe slightly for clearance with the floorboard. The 2.5" pipe can be tucked really close to the body (I am a little too close and am getting banging here and there). It has the same - or better - clearance than my stock "Y" did.

I've always been able to get a great tuck without banging using that method. Once the clamps are tight the whole thing is solid.
I just worked on a catback last weekend where the ipipe was literally sitting against the floor in the tunnel and you couldn't move it by hand because of how tight the pipes fit together. Loosened clamps, pry bar'd it over, shoved wood blocks in, tightened the tar out of the clamps, got a good 3/4" of air space afterward.
