I have the American Thunder #17139 dual system on my 69 and really like the stainless tips. Does anybody know if the same system will fit a 67? The kit for a 67/68 is a different number but all of the parts are the same except the tail pipes. I know the 67/68 tail pipes exit just behind the rear wheels but the guy who's car I'm working on wants the 69 tail pipes. I have never tried to adapt the 69 tail pipes to a 67/68. Will they fit?
Thanks
Jim

Cool

I would think the 69 would bolt up to a 67/68. Maybe the last hangar on a 69 was/is further to the bumper since the pipes exit at the bumper.

Just my thoughts.

The hangers are further back on the 67/68 exhaust. I used it on my 69z/28 and had to drill new holes. Looking back I wish I had put the correcr tailpipes on it, they look better. the kit should come with everyhting including new hangers.

I have that system on my '68. Not remembering the exact #, but it's listed for a 69. and has stainless tips out the back. It fit perfectly. This was years ago... but I think I'm remebering that the kit listed for 67-67 uses a single tranverse muffler, and dumps the tailpipes straight down behind the tire

I think the single muffler might only be the Force II system (which is a good sounding system). For the '69s anyway, it dumps out the bumper.

Well I just finished the installation of the system in the 67 and it fits perfectly. No problems at all.

For the 67 and 68 application, is this system a clamp together system? Does it also have an equalizer (crossover)? Does it install fairly easy to headers and with little modification? Thanks!

The 67/68 system is easy to install and very complete.It clams together but you should probably use muffler cement or whatever they call it so the pipes will seal a little better.The only unusual part is the collector is a two piece assembly that needs to be welded, I went to the local auto parts store and for 10-15 bucks bought a new set of collectors instead. I don't have a welder.

It does come with a crossover (H Pipe). You do have to make some welds at the header flange but the system looks great and sounds good too. I didn't use muffler cement at all. No leaks.

if you buy fowmaster makesure you keep your receipt for the rest of your life. after 3 years i changed headers and needed the 45 deg pipe that goes to the collector, 21.00. thay wouldnt sell me the part without a receipt. i got one from a buddy but it was a hassel.
