i did the 408 from tsp and it was easy, everything bolts right up no problem. i think im running to small of a cam but its my dd so i dont mind(f13 cam). i have the 1 3/4 headers and i have lots of power, so im not disappointed.. but if you have not bought them yet, yes buy the bigger ones. im also running the trickflow 215 milled to 61. also i did the install from the top and had no help..my wife lowered it in the car for me :0

There is a group buy going on right now if you hurry, so you can get $50 off the $499.99 price.
Worth every penny of it, let alone at a $50 discount!

I ran the poly mounts to insure i would have no fitment issues from sagging factory mounts. As far a lowend feels no differnt to me. I do have 4.56 gears that mite have something to do with it. And i paid the $499 for mine didnt have a group purchase at the time. I would recommend this to anyone. And wouldnt worry about a 1 3/4 header when you can get this at a great price. You have room to grow.

Think of it this way... intake and exhaust flow have to balance out to maximize power.
It starts with the cylinder heads. Your intake runner outflows the exhaust by a good amount. So typically they bias the cams with more exhaust duration to 'help out' the exhaust to get a balancing act.
So now to get more air in, you upgrade to a larger intake manifold and throttle body etc. To balance out that extra air in, you need go slightly bigger on the exhaust. Exhaust is a little funny though as it's temperature flucuation from exhaust port to tip is a huge transition, which in turn changes the pressure, so it's a balancing act. Too big and you lose velocity in the exhaust, think garden hose with a big 2" hose hooked up to the bib. Too small and you hurt flow by it being too much of a restriction.
In summary, if you've done heads and cam, and a bigger intake, going with 1 7/8 headers into a 3" ypipe is the next logical step.

The LS heads flow great for a factory head so that was one reason i went the the 1 7/8 and TSP price is right, so I will take the Very Slight loss of torque if any to gain at the top end. I dont Race from idle to 3000 Rpm so wasnt worried about it.
