options for exhaust

[verbalhologram]

GTI Polo, can you give a quick review/opinion on your DP?
Got mine book for 5th Jan...tnx.

Also what size is it over stock(the DP),just want to what to ask for at the exhaust shop.

My Dump pipe is the APR unit 2.5 inch, includes metal cat converter as well.. My car also has the APR tune as well. (V1). I think any professionally made 2.5 inch dump pipe would perform as mine would. I chose the APR unit as I dont wanna stuff around with people that dont know these cars. Pros and cons below

Pros:

- I feel like the car is making more power than before, doesnt drop away as much above 5000rpm like it did before. Revs out more cleanly. the car feels quick, no doubt.
- Im not sure if its just in my head or not but it feels like I dont get as much heat soak as before. The power feels like it hangs around a little longer than when I had the standard dump pipe on it.. Maybe less restriction keeping the turbo a lil cooler? Can anyone confirm this?
- It has a slightly more gruff note to it. Not a great deal but a wee little bit deeper. Not sure if thats a pro or con.
- Supposed to make about 7-10rwkw extra. Feels a little better than before but you not gonna feel like its a completely different car. Its a reasonably modest gain in power.
- The APR unit looks like its quality made.
- Fuel economy?? not sure if it made a difference.

Cons:

- The car has an ugly resonance from about 5000-6000rpm. Rev it up and back off and you will know what i mean.. Sounds like a Hyundai Getz revvin it arse off up top. Drowns out any sence of Turbo whistle whatsoever, lose that refined feel as it had with the regular dump pipe on.
- There is a tinny sound on part throttle, not an exhaust whistle but much rather like a chain jiggling around under the car. (ive had it checked and its not leaking or anything). Must be the flex pipe between turbo and cat. I think its just thinner metal than standard so you hear a few extra things. this is the second APR dump pipe unit on the car so its common to both of them.
- Not as much performance boost as the APR chip makes to a stock car but its definately better than before.
- APR unit is expensive.

Overall, Im glad I upgraded the dump, it makes a worthy difference to performance and adds to the enjoyment of my ride. Nothing is going to have all pros and no cons.

hey gtipolo, a couple quick ones:

why is it your second unit? ive heard that the bit where the dp bolts onto the manifold (is this correct) can crack/ seal can be compromised- is this what happened with yours?

also, have you driven stock tune + stock dp vs. stock tune + apr dp? what did the butt dyno say?

cheers.

apparently there is little to gain from a full exhaust system power wise.. Just spend the money on the dump pipe..

My car has the dump pipe and you would swear there is a full system on it. Far from quiet. There is also some ugly resonance between 5000-6000rpm..

hahahahaha.

I had that terrible crappy sounding noise. It was horrid. How the hell do you ever put your foot down without feeling embarrised?

I quickly redesigned my dump pipe and now have a much better noise.

Edit: Wait what. I just read it was an APR downpipe... Did an exhaust shop fit it? Or apr.

[GTI POLO]

APR fitted it.. Its the second APR unit on the car and both have the ugly resonance.. The reason why I had a second unit is the resonance.. But the second unit did the same thing..

Derek at Euro autotek fitted it, an authorised APR dealer.. ?????

Its the the greatest sounding exhaust but it goes good..

No Derek at Mona Vale fitted it.. He took off the first unit and there was no sign of leaking.. (would have carbon marks but the flanges per perfectly clean.. Just makes an ugly resonating noise...???

Hmmm, stock tune + Stock DP is obviously stock. Stock tune and APR dump pipe unit, I have not actually driven it like that?? The tune is the biggest kicker, Id do that before the dump pipe.

I am beggining to think,I will just leave the exhaust as is for a while ,and start saving for the APR Flash(which will take me ages to save for).
I might visit my local exhaust shop though and just check if there is anything they can do to get a slighly deper note without messing with the stock configuration too much,

thanks for everyboby who made suggestions ,appreciate it .

If you can get the dump pipe done cheap do it.. can only benefit.

The resonance I describe doesnt occur if your on the throttle, just when the car is decelerating up top... Say give it a hit to 6000rpm and back off.. then it resonates.. But under wide open throttle its fine... No funny noise there.

DP= support mod, no? as in, good for back end of turbo?

had a good chat over the phone with head of service dept of dealership i bought my car from- top blokes-- no warranty guarantees, but the boys are interested to see what dp does to affect flow through lambdas either side of stock cat, after i get dp done.

keep in mind i have a tdi so im always on boost- 450aud seems cheap to facilitate turbo longevity.....

golfman!!! hop to! lol just kidding i think dp is early in the new yr.

I've got a custom 3" DP and have never experience any resonance or any other problems ( ie fault codes ). My 3" DP gives a really nice growl when she's on boost. I would like to get a new muffler(ones with bigger twin pipes) so as to give the rear end a tougher look.

where and how much did you pay for that??

[binnyvo]

I got it done at Newcastle Mufflers in Newcastle, about 2 hours north of Sydney. Only cost $350 all up.

[Chipped]

don't forget tho that the APR incl. High flow cat converter at 2.5" stainless steel with the DP

[MissVuks]

Didn't want to start a new thread so i revived this older one.

I am considering an exhaust for the polo but want to know what the best options are... I want performance gains and nothing overly loud. I hate cannons, want to stick with the twin tips as i want to leave it looking stock.
Evidently i do not know much about this, so please educate me on what would be the best route to take.

Recommendations of places where to get this done would be fantastic and how much $$ this is expected to cost. Any information given will ultimately be the deciding factor, so be nice hahaha

Thanks,
