Escort mk1 1300GT exhaust

Recommended Posts

1 5/8 inches or 41mm GT

1 1/2 Inches or 31mm 1300

 

If ive read my data book correctly.

Ive got a 1300GT also. I hope to do a few mods in the future on mine. Cam, carbs etc. I think i read somewhere on here that sub 150hp its best to go to 2 inches max. Any bigger and you start loosing torque/power.

Thank for the reply.

I have a question. How do you measure the diameter? Internal or external?
