UK-POLOS.NET - THE VW Polo Forum

in january i fitted a jetex stainless cat back exhaust to the gti and after a while driving it i dont feel any improvement for the extra noise so im tempted to remove it and refit the standard but with a de cat pipe to free things up. the original plan was to get a de catted downpipe made to match the 2.5" jetex but after using the car daily i think its gonna be stupidly loud! just wondering what people think the best way to go is? i was also looking to buy a manifold soon too but not sure if is worth it? any ideas?

I'm running a Jetex cat-back system. There is an increase in power but its only slight.

You can't expect to get huge power gains from an exhaust upgrade on the Polo. A manifold can make a difference but depends on which one you get.

To be perfectly honest I think even if you have all these upgrade it won't make a huge difference because at the end of the day you need to remember it is a Polo after all.

What he said...

The polo is relativly highly tuned by VW anyway....125hp out of a 1.6 is fairly high for a standard production car...

I know some of the performance exhausts out there are actually worse for power than the standard one!

The standard exhaust and induction is actually quite good....the weakness is the head and intake manifold...

If you really want to increase air flow through the head the best way of doing it would be to take the head and intake manifold off and clear out all the casting flanges and have the intake matched to the head as well as having the combsution chambers balanced....but is there really any point on such a car...

i heard a remap on your engine makes for good gains?

A remap with no other mods will probably see 7-10 bhp from the GTI engine

oh right i though it was more nice cars though have any had a 1.8t conversion?

cheers for the input guys. i will be needing a remap soon as i have schrick cams to go in. i just wanted to get the air flowing better first but it looks to be within the engine rather than bolt ons.

There's been a few, no frequent users on here though

u want your polo 2 be faster !!
Get your name down on a arb then!
in my boy racer days i could keep up with my mates on the strait bits in the saxos and corsa's but round the corners is were i used 2 struggel, a arb will sort this

i will be having one of those arbs as soon as i sell a couple of bits!

My way of thinking is: -

If you want to go faster, just buy a faster car!

Yup...You could spend a couple of grand getting the latest ARB, the latest suspension bushes, remap, magic dust etc....

Or you could spend that couple of grand buying something a lot faster!...The mk5 Golf GTI 1.8t can be had for silly money .....
