Default Summit headers install - pic..

Just got done installing the Summit brand headers onto my '78 w/ Vortec heads. Drives side looks good. The problem is that the passenger side header flange at the bottom seems to be angled slightly downward instead of straight back. I would think that it should be straight back when it eventually meets the pipes.???
Not sure if these pics show the angle very well:

I have these headers on my 71 I think they fit pretty good. The passenger side is just as you have described a slight tilt downward.

My set is the same way. I have flex piping connecting the headers to the pipes right now until i have time to bring it to an exhaust and and have it hooked up properly

I have a set of 30 year old Cyclone headers on ours and the right side is just like that. I wondered if that was just this brand, but I guess not.

You can see it in this photo

I'm a firm believer in that you pay for what you get. We also as consumers drive the market. If we continue to buy sub-standard almost fit parts the manufactures will continue to produce crap.

I recently got into it with a radiator builder who for the past 10 years has been selling radiators that don't really fit. What is even funnier people defended the radiator builder that it was Okay to have to bend our stock radiator mounts and the rubber really doesn't grab onto anything.

So if you don't send them back with a picture to Summit saying they are a crappy product the manufacturer will keep making crap because he doesn't care

I did not think it was a production error. If the header was level at that point the reducer would not fit.

I'm surounded

Do these headers point down and require a stupid flex pipe or clearance for a reducerer?

Ah, and thus the problem with America. Sub-par and just ok has become so common place and people are to lazy and complacent to complain.

There is a lot more room in that photo than what there is on my car.

Now I see the other point of view. If I make the primary length too short I then have to make a down angle on the collector to the pipes to clear the bottom of the firewall and do it on one side so my product has no symetry from side to side.



Like I ordered two front ultra performance tires of one size and two rears of another size and the person called and said bring your car on down. After delivering my car and keys and filling out the paper work I left for an hour. Upon my return I was confronted by the manager that he couldn't install my tires. Because you can't have two different sizes because you can't rotate the tires. I said WTF!!!!!!!!!:crazy: This was the manager!

Did you maybe consider that my car is on stands of some sort? Because the pipes are a foot off the floor.

I was not really even looking at that space. You have a lot more room at the top. On mine only half of the end of the collector sits below the frame. I could not run a straight pipe back from mine either not because of the angle but mine is a TH400 and the pipes run around the pan. I have 2.5 factory exhaust and it comes pretty close to lining up I too will have to have an exhaust shop connect mine as I have about 4 inches of the flex pipe.

Just Email them the pics you have shown us making sure you include pics of the other side which is good so that they cant judge something you have done and they will make amends. I have never had a problem with Summit replacing a part even though it takes a bit of work and time. They are a big mob so just be patient and battle for the win because the collector should not face down that much ..... to clear my floors mine have an offset,angling down is the bubba solution.

When I bought this flex pipe I kept looking around hoping no one I knew was going to see me and now here I am posting it on the internet.

I happen to be a thinker. When I see a problem I fix it.

Our cross member is an exhaust problem and it routes hot pipes right over next to our transmission.

You build and exhaust from the front to the back. You don't bolt a pair of headers on a car with an existing exhaust and expect them to fit.

No they shouldn't point down I sent a pair of DynoMax headers back because the pointed down. Your headers should be horizontal and build the rest of the exhaust to fit where the header collector ends

I did not expect them to bolt right up to the factory pipes without some pipe bending.

Is that what you meant by "If the header was level at that point the reducer would not fit ?"

A muffler shop is not that expensive unless you do what I did. They do this all day and can attach the headers to the rest of your exhaust in 10 minutes.

Problem is do you want them on an angle downward like that ? I know many members here have them that way when the Dynomax ceramic coated headers came out for $200 they all angled down, then you have to bend a piece to get it back up level

Seeing what I have seen here and knowing what I have got it appears that the Summit header collectors do not drop down as far as others and they appear to be shorter. By their design if they where total level I think there might be some clearance issues. They tilt down at the point where the stock exhaust bends. up They install fairly easy and fit around the engine well. With all that said I think the angle of the collector is by design rather than error. Correct way to do it or wrong way to do it I am not sure. After seeing how some of other brands fit I am thinking they fit a bit to close to the floor pans.
Just my thoughts
