Does anyone know if the 50 series flowmasters will fit under my 65 coupe? they are about 23 ' long and it looke like there is not enough room.

 

Probably not, but there is a sure way to find out. Get a tape measure and crawl under your car.

 

There are different kinds of 50 series. they are all 17-18 inch's long then the pipeing makes them 23-24 inch's.

I went and looked and there are 15 different 50 series

 

I bought a kit from mustangs unlimited,got everything but thetail pipes, they were back ordered. The flowmasters are series 50, 3 chamber and they are 23" long (including the inlet and outlet pipe). I put the "h" pipe on and the mid section pipes then held the series 50 up to the underside. The outlet pipe ends up close to the axle housing. I'm guessing that the "kit" is wrong. Will know better when the tail pipes come in.

 

50 series come in two lengths 17-18. The pipes make the thing 23-24. There are 15 different configurations to the 17/23 and 18/24 inch 50 series. Go to Flowmasters web site and look at all . If a 17/23 don't fit then a 40 series is shorter, But I think they(40s) only come in two chamber,
