SLP Headers & Cat back system I am going to buy this system from SLP can anyone tell me why I need the cats? Can I just weld in two three inch stainless pipes instead and not worry about any problems by doing this,I dont live in the states so emmisions laws here are more relaxed so thats not a problem.

The cats will make the LTs and LM sound better, and enable you to pass a sniffer test if required in your state. I have this exact set up, and I love the LM, but would get other headers if I had it to do over again. They hang way to low. I think QTP and TD is my next exhaust set up.

No there will not be any harm in not putting cats on, but instead of welding in some pipe just buy an ORY pipe, it has no cats on it. You will have to get O2 sims for the rear O2 sensors though, they arent that expensive though.

well the slp headers take away about 2" of ground clearance theirselves minus another inch or two, your headers will be on the ground, literally every time you hit the smallest bump. talk about pissed off my buddy rubbed a hole in his im glad he bought his first, i'm gettin pacesetter, what he has now much easier to install (less cussing)

i just finished installing my long tube SLPheaders,(they are very low) you cant lower ur car after installing them,otherwise ull have alot of problem driving ur car.
cats,i removed mine,the car is not in the united state so i dont have to worry legal stuff.
in my opinion,taking cats out are much better for you engine,i had 3 inch y pipe and borla exuahst the car sounds sooo good and sexy.
but to do this(taking cats out) you have to keep in mind that you buy the o2 similater and connict ,so u dont have ur check engine light on.
and good luck driving ur baby.

QTP is Quick Time Performance....they are a sponsor here. They, together with Kooks and Stainless Works and Dynamaxx make the most popular Stainless Steel headers. I would get any of those over the SLP setup.
TD stands for True Duals. As you know our cars don't have a true dual exhaust, so a lot of guys go for custom made true dual setups that go either over or under the rear axle.

Off road Y-pipe, it is the pipe that connects the headers to the rest of the exhaust. The normal Y-pipe has Cats on it and an off road one comes without Cats.

QTP make LT headers & TD = True Dual exhaust. The TD can be with either and X-Pipe or an H-Pipe, which both look like they sound. There have been some awesome examples w/pics posted if you search for "True Dual."
