S&P Headers

[motoxlifer]

Sweet! Good job Nitrous. Just wish you would have done this about 6 months ago. Maybe while they're listening to you, you can get them to change their gayass collectors. Hell while your at it get em to just go ahead & make some longtubes.

[NITROUS]

Ya, the collectors will be a pain in the butt to change gaskets due to the bolt to header clearance I made sure I put all of the nuts facing towards the ground to make things easier.

Just form yourself a large tube and weld it to the flange instead of using the collector. Then you can make them like a long tube. I wonder if that would really work since the exhaust gases would already be combined. A large tube where the stock flange is, down from there with a 4" tube like it were a standard long tube exhaust header and then to a standard reducer flange.... I wonder what that would do to the feel of the exhaust.

[NITROUS]

That would be pretty easy. I think it would act as a long tube header.

[RedHeartbeat]

anything from a 3.25" or larger pipe would provide more flow area than four 1-5/8" diameter exhaust tubes.

[NITROUS]

I agree. I think they built the flanges for flow characteristics. All of the tubes go into a 5" area that swedges down to a 2 1/2" pipe. Too bad it has the 02 bung in it already, if it didn't I would get mark to bump it up to a minimum of 3" I'm running 2 1/2" exhaust now but I'd replace it with 3" if that were the case. Right now anything larger than the 2 1/2" flange pipe wouldn't help me out since the 2 1/2" exhaust would restrict it. I guess we could always install cutouts.

How do you figure they built them for flow characteristics? The collecters reduce down to 2 1/2" so abruptly I can&#39;t see how they could possibly flow well. Sorry but I hate these headers. The only reason I&#39;m runnin em is they&#39;re the only header available & I hate manifolds even more. BTW they sell collecters without bungs (or buns as S&P calls them). I thought about cutting the collecter off just before it necked down and having the exhaust shop weld on some 4" pipe or so & then reduce it down to my current exhaust. Might as well have them weld the collecters to the header while they&#39;re at it, so I wouldn&#39;t have to worry about any more leaks. My driver side coll. is leaking now and driving me crazy. I can&#39;t get the bolts tight enough with the header installed to keep it from blowing out the gasket. They&#39;re welded to the exhaust so I will have to cut them off and have them rewelded. Did I mention that I hate these headers?

[NITROUS]

LMAO&#33;&#33;&#33; I think they have better flow than the shorties. JMHO Let me explain myself, I should have done that in my previous post. If you took this design, bumped the collector up to 3" to 3 1/2" and had the collector welded into it and not bolted I think the flow design would work. I&#39;m supposed to be getting the dyno papers from these headers which are supposed to increase HP by 20. I agree, they could have made a long tube and eliminated the mid length but Danny said they didn&#39;t have a jig jet since they use pre bent tubing. The reason they left the header like this is because your average joe isn&#39;t gonna put 3" or larger exhaust on his truck. He&#39;s gonna stick with the stock 1 5/8". What size exhaust are you running? 3" or larger and dumping it in front of the rear axle? If not, a different header isn&#39;t gonna help out that much.

Hey motoxlifer, did you go by the header break in procedure? I&#39;m sure you did but I thought I&#39;d ask.

[motoxlifer]

Ummm what header break in procedure? I guess I missed that part. What is it? I&#39;m runnin 2 1/2" exhaust dumped in front of the axle. What do you mean the average joe is going to stick with the stock 1 5/8"? Is stock exhaust tubing 1 5/8"? I thought our primary tubes were 1 5/8". I did some reading on exhaust sizes and from what it said with my motor & mods it would be a waste of time & money to run 3" pipe. I like the looks of these headers & I&#39;m sure they make some extra power. I&#39;m just pissed off at em because of the problems I&#39;ve had with them.

[NITROUS]

I was pretty tired last night I believe the stock exhaust tubing is 1 7/8. Nevertheless, it&#39;s way too small. Ya, they have a break in procedure where you make a short exhaust run and then tighten everything back up before you drive it. I&#39;ll have to post what it says. It was really simple. It also tells what to wash the coating with. I hear what your saying about the headers though, they&#39;ll just have to get us by until we can find something else.
