Help with exhaust(cats, cutouts, etc.)
My first major type of mod will be headers and exhaust with cutouts.
I want long tube headers, 3" exhaust with with electric cutouts. I've looked at pictures of the dynatech header/cat system that jeg's sells. First off....is this a good setup? Then, where would I put the cutouts? Looks like they would have to go behind the cats.....so, I'm guessing the a section of Y pipe would have to be cut out behind each cat and the cutout welded in??? Thinking of putting a magnaflow catback system behind it....good/bad???
Where can I find electric cutouts? Are they shaped like a Y with a butterfly?
Thanks for any help

An ideal setup would be Pacesetter, Jet-Hot or Hooker headers, catted Y-pipe in your case and a Magnaflow cat-back is a nice choice. I am not sure about where to put the electric cut-out. It would go after the cats, but I have no idea where on the Y-pipe.
THIS IS WHAT I WOULD GO WITH:
Pacesetter: $375
TSP catted Y: $325
Electric cut-out: $150
Magnaflow: $375
Total: $1225 + labor
If you went with the Dynatech headers, you would be paying that amount ($1,200) for just those headers.

Yeah, the Dyna's seemed a bit steep.....$1300 for headers, cats and Y. They had a pic of it all assembled in the Jeg's catalog. I have not priced the Kooks....I assumed they would be $$$$
Could someone attach a link to some electric cutouts?
Thanks for the reply

Check out www.quicktimeperformance.com for everything you are asking for. They make the most powerful headers for our cars. They make a y pipe with there electric cutuouts already built into it. But that y pipe does not have cats. If you need cats get the cat y pipe and one electric cutout and weld it on the intermediate pipe. Dont bother with the dynatech, they use a 2.5" y pipe which is restrictive when you start making power.

If this is the case there will be little or more likely NO GAIN in power, there would be a massive increase in noise however.
So if the Cats are restrictive then it's a waste of money putting a cut after them.
Use this formula as a guide:
2.2cfm for every 1bhp
So if you plan on having your engine making 400bhp (engine NOT wheels!!!),
then 2.2 x 400 = 880cfm. This is the minimal flow capacity. If there is to be a cat/muffler per cylinder bank, half the figure. As of course there is only half the number of cylinders and exhaust gases.

Electric Cutout: QTP - $152
Exhaust: Magnaflow - $369

It's all up to you on what you decide because it's your money and your preference on what you want...but this is an ideal setup and a great setup too.

Definatly Coated Pacesetters, unless you have the big bucks to spend on KOOKS QTP etc. For the catted Y TSP is supposed to have one of the easiest to bolt up to any LT. And If you like the whole "catback" look there are alot better compaines to use for that, BORLA, CORSA, LM, BORLAMOUTH. Or if your wanting more of a "race" type exhuast look into some true duals, its going to run you pritty damn close to the same price as the cutout and y and catback. Here is my new setup, Pacesetter Race LTs, summits x pipe kit, sweet thunders and dumps before the axle. If you want to see pics just search, many of the guys here have setups and pics to show. Good Luck man!

I'm guessing that by removing the cats I would have to do something to trick the 'puter? I would prefer true duals........3" all the way back and dumped. Now, with no cats and XR-1's would cutouts make much difference?
Obviously I'm a bit ignorant to these things.......I know how I think it should be done....but need some experienced advice.
Thanks guys!

Even if I went with the oval instead of round? My car isn't lowered.....yet....planning on the eibach springs and 18's all around.
Just trying to avoid performance and clearance issues. I saw the some headers reduce clearance....
Thanks for all the tips and recommendations so far
