Here's a question that'll really show my ignorance. I've never put hedders on before. Do you go to a muffler shop to make the remaining pipes and mufflers or should you get the kits form the hedder mfg? Hedman seems to have universl reduces and extensions, Dynomax looks like they have a complete dual system specifically for the model car.
BTW I have 68 Camaro RS conv 6 cyl 4 speed going to be 350 4 speed.
watch what size you order, most are 2.25 or 2.5". Flowmaster makes two kits for the first Gen. 1) is true duals w/ H-pipe 2)duals to single muffler and twin tailpipes ( like stock).Although you could get one made at the local muffler shop.Its your car/choice.
I can tell you right now that most kits will not fit convertible. I have a conv. with a 350 engine and A/C.
The pipes from the headers back to the rear axle will have to be custom made to fit over the x-brace on the convertible cars.
This is not a big issue for a qualified exhaust shop. The rear portion of the kit should work without modifications though.
Also, watch out for clearance of the headers with the power steering box and A/C too, if you have A/C. I do, and the Hooker Competition headers cleared the A/C box with not problem and were very close to the p.s. box, but cleared it. Overall the fit worked without modifications to the Headers, but a lot of people have had problems with various headers.
You can check out my website for more pictures, etc.
Thanks for the tips. When we talk about A/C on a 1st gen, is there a difference in factory A/C vs Vintage Air as far as hedder clearance issues? My 68 does not have factory air but I want to add Vintage someday, probably after the hedders are on.
I've got a 67 RS Convert. I used Hooker Comps and the Flowmaster American Thunder system. Everything fit perfect except I had to take off the X-brace. Some otheres have done this too but used a spacer to reinstall the X-brace. To me, I think the brace will hang down too far with a space so I just left it off. I plan on using suframe connectors to make up for the loss of the brace. This was the best price and system out there, however I think the exhaust is a little loud for me.
Winch, one other thing to keep in mind. The flowmaster exhaust system is mandrel bent (best flow) whereas I'm betting the local Meineke doesn't have a mandrel tubing bender (expensive) to make your exhaust. What this means is the bends in a normal bender seriously restrict the exhaust at the bends. So if you have 2 1/2" pipes made the bends may reduce the flow to an equivalent of 2" to 2 1/4" system. Check out your stock exhaust and you'll see the bends and how it kinks/restricts the flow. My 2 cents.
you should not have a problem with the vintage a/c setup. The interference comes into play with the stock factory air box.
I would not take out the x-brace if i were you....
there has been some discussion of the x-brace issue, you may want to do a search for it.
Winch, there's really no way around removing the x-brace if you want a 2.5 system. Unless you get a custom mandrel bent system, and now you're talking really big bucks. I think the consencise is to remove the X-brace and install subframe connectors, or a spacer to replace the X-brace
