1.4 RT Downpipe

[donsrno1]

Having recently changed my exhasut from the cat back and fitting a decat I want to change my downpipe because there is a big dent in it as you can see in this photo:

The dent is actually quite bad and you cant see properly from that photo how bad it is.

What I wanted to know is whether it being dented their is likely to affect the performance and reduce the effect of any other changes to the exhaust system as I was hoping for a wee bit of improvement in the performance of the car with the new exhaust I fitted but I havent noticed any real diference.

Does anyone know if the downpipe off a Mk1 Ph3 1.4 RT (Mine is a Mk1 Ph2) would fit OK and if it would be a case of a straight swap as I can get a hold of one off this site but am unsure as to whether it would fit or not.

Would it be worth fitting an aftermarket downpipe and if so where could I get one and what sort of price would it be?

Thanks.

wont be a big difference on a 1.2 tbh, it will only really effect it slightly by slightly slowing the airflow but not noticeable.. if theres a hole or a crack in it then itll be loud as hell and then itll affect power (i know!)

depends if the 2 engine numbers are the same which is doubtful

powerflow mite be able to make one up but gains would be minimal

Thanks.

is all that matters is the oxygen sensor location, whether its in the manifold or down pipe !!

where the downpipe meets the manifold i think.... (well it is on mine!)

On my 1.2 it was in the fanifold.

My downpipe is dented to f**k like that, its cus of those f**king raised manholes.

A new exhasust is gonna amke 1-2 bhp if you are lucky, a dent in the downpipe is prolyl gonna make 0.1 bhp, IF that

What Lunner said mate

I would just leave it as it is

recently done the same thing to my car and changed the downpipe, it was only £35 new from a auto centre, the sensor shud b in the manifold, i didnt gain much power wise but the engine revs free'r.
