I didnt saw much topics for fiesta st here, I hope there is few owners...

I need information about flexy pipe. On fiesta st standard flexy pipe is the thightest pipe in exhaust system, it have only 42 mm (same as KA 1.3) , so there is restricted air flow.

does someone change it for miltek or moongose flexy pipe (60 mm) and is there any feelable increase in torque (someone told that there will about 20 Nm up, and about 5 bhp) ?

 

i know of a lot of people have changed it and say thats its one of the best mods you can do to the car, best bet is to go check out fiestastoc.com, full of helpuful knowledge and is completely deicated to the st. Plus if you jopin up they can off good discounts.

 

Correct, it is standard at 42mm and expands to 60mm with a different flexy.

The flexy will give you around 5bhp which isn't so noticeable but you'll see about a 15% torque increase which is certainly worth the Ł130 or so it costs.

Definitely a worthwhile mod
