CMC Speedster - Need info on Seats and Exhaust

Purchased a CMC Speedster project. Trying to complete; any ideas on a comfortable seat that will fit in the car? I have the fiberglass seats but would prefer a little more stable seat. Also having problems with the exhaust system. Purchased the Monza dual exhaust but it hits the bottom of the car body....any ideas?

Seats from a Porsche 914 - any year - will fit like they're made for it. Make sure you get the seat glides AND recliner stuff to go with them and you can have both sides bolted down in well under a couple of hours and then they're adjustable!! I used a couple of 1/4" thick by 2" wide straps across the underside of the pan under the seats to run the bolts through and give the whole assembly more strength. Makes them feel much more solid.

914 seats all came with integral headrests, which I need, but the headrest can be easily cut off and a decent upholstery shop can modify the material to nicely cover where the headrest was if you prefer the lower seatback look.

Can't help much with the exhaust. I have a Berg Dual Quietpak (GB932?? - it's been a while) and it doesn't hit the body but hangs a bit low. Other folks are running A-1 systems, but first you have to tell us what you have for an engine displacement, valve sizes, what carbs and cam.

Where are you located, Brenda? Someone might be able to point you to a good Porsche salvage yard nearby for the seats. I got mine from the 356 registry years ago.

Thanks... gn

I have the 4 tip Monza on my CMC --- I heated where the tip pipe goes into the muffler (with good propane torch) and bent the dual tip pieces on each side down 1/2" or enough to clear.

Some say old Mazda Miata seats fit too. Or you can buy new VS seats which resemble the Porsche 914 seats (sans headrest).

Thanks for the information; very helpful. I only need about 3 inches to clear the body. Maybe the heating and bending will work; will definitely try it. I am located in Kentucky.

Exhaust not clearing by 3" that's a lot, the pan-chassis may not be reassembled exactly level.
Do a search here for a Hide Away exhaust it runs up along the passenger side on the motor.($170.00)
Most comfortable seats for me in my past CMC builds are Vintage Speedsters seats that have extra padding.

My seats are very comfortable and are Vintage seats with 914 seat cushions. I switched the covers from the Vintage to the 914 bottoms.

I had planned to use the entire 914 seat including the slides, et but when I tried just the 914 cushions I knew that was the fix I was looking for. My butt was a tad too wide and the fiberglass sides of the bottom part of the seat (where the cushions fit) raised me above the sides---super comfortable. Then I gave the rest of the seats and hardware away to someone here on the SOC site.
