Best headers/y pipe for an eps cam...? Alright, decided on getting the EPS 264/246 cam.
http://www.engpwrsys.com/index.php?a...d&productId=10
There's the link to it. I've heard stepped headers are better for a bigger cam to make more power than basic longtubes but is it true? I really want the hooker longtubes for my gmmg but will the stepped headers make that much of a difference? Also, whats the difference between stepped and longtubes? And what's a good catless Y pipe to go with the headers to my gmmg mufflers? Thanks!

Alright thanks. I'll put cutouts on but those wont be open too much. Are the ARH headers stepped or just basic longtubes? As far as longtubes go I'm really leaning towards hooker because I love the way they sound with a gmmg and catless y.. unless you can point me some place with a good sound clip of the arh headers with a gmmg catback...

Headers are headers there all gonna sound the same, that is unless the merge is crappy. Your gonna be paying for fit, quality, and material. I personally went with kooks longtubes and ory, I live in the midwest and loove to drive in all weather so stainless was a must. They fit like a glove, install took less than an hour for me, I had a car lift tho.

since u r obviously not worried about smog u should get the TSP 1 7/8 race style headers and the TSP y pipe. great stuff at a good price. than take off your whole AIR and EGR setup and smog pump cuz u will not need it and lose some pounds off your car. it will make your engine bay look nice too.

I just ordered a set of TSP 1" 7/8 LTs and off-road y-pipe yesterday. Hopefully I can get them installed by next weekend. I plan on putting a cam in this summer so these should accent it nicely.

That cam according to the link is:
"Designed For 5.7 to 6.2 Liter Engines With Stock Or Stock Type Intake Manifolds"... (and Cathedral Port Heads.
Extensive Computer Tuning Required. Broad Power Band.
Dual valvesprings recommended.
1500 to 7200 RPM Operating Range.)
Why match headers up with a exhaust intensive cam designed for restrictiive exhausts? In theory, that cam should not respond as well as alternative designs to headers of any type. What am I missing?

I wouldn't say this is designed just for restrictive exhaust, but I more or less agree. All of the EPS grinds have somewhat wide splits with generous exhaust duration and lift. They are just trying to make sure there is good enough flow out of the head for high RPM... if you have great exhaust valves, ports, and exhaust system then consider asking them about a custom grind with less exhaust duration and see what they say. But I bet the opinion of the cam guru at EPS, with OEM style heads he would prefer that ratio of intake to exhaust duration.

stock heads and stock manifold/throttle body with the exception of a K&N Intake. Not gonna blow thousands of dollars on nice heads and a FAST manifold so the only other things id probably do is an ls6 manifold and maybe port the throttle body and heads. Gonna have it dyno tuned probably on a mustang dyno (closest one to me) and I'm not worried about emission testing until I have to cross that path in a year and a half.
