Went out in the car yesterday and the exhaust started to rattle a bit - didnt think much of it. Drove up the town to see my mate - came out of his place and the exhaust back box is hanging off bigtime!
Headed down to my parents place and got the car up on blocks so i could have a look underneath - however at this time its snowing HARD!
I found the back box had totally split away from the rear pipe. So i cut the old rubbers and just chucked the backbox in the garage. By now I looked like the abominable snowman!
Drove to work with no back box - the sound is pretty sporty and the boost picks up really quickly!
My query is what do you guys have on your GTD's?
Whats the best diameter to use??
-
Most of these guys have no backboxes!
AFAIK the best is 2.5" straight through from turbo with no silencers.
-
3 inch downpipe(or 2.5 can't remember) and 2.5" straightpipe no mufflers, no cat
-
So a straight through system with no boxes? is that legal?? (UK)
-
It may be too loud to pass the MOT.
-
depends on the tester. cannot be louder than 98db(like a freeking jumbojet!) otherwise you can be prosocuted by the police for noise polution. so yea it's legal, just make sure your mot tester is a sound guy :)
-
or make sure he wears a hearing aid :lol:
-
my car is not much louder than stock, the turbo acts as a muffler. definately doesn't sound like a harley or even a vr6 with an exhaust
-
without anything on it past the mid section its ok at cruising speed, but floor it and its howls - plus you can here the turbo loads!
-
So you saying that If i turbo my 1.5L with my souper loud ass exhaust, It will actully quiet it down?
I got a soup can muffler on there and it's sooooo loud at 3000RPM''s :oops: sounds nice, viberates like hell and defonately getting me tickets
-
2.5" mandrel bent custom downpipe, 3" side exit...no muffler nothing. Sounds like a big truck and i still cant get over the sweet turbo noise it makes... Car is loud when you step on it...but in normal driving its not bad at all. Ive been past a few cops....havent gotten hassled or pulled over yet. I love it. :mrgreen:
-
new exhaust system ordered!

£160 all in! ;)
-
Why are there so many mufflers? I'd use just the black rear mount muffler only.
-
I wouldn't even use that one.
If I was to any of that it would be the small resonator in the middle of the pic.
Seems like an awful lot of restriction in that system.
I'll bet it will be a quiet SOB..
-
I just use pipe from the turbo back... that and if you extend the pipe past the car a bit the drone goes away a little ;)
I drove one car for months with it cut off 2 feet after the cat! boy did it spool fast and look like the car was on fire when it smoked a little
-
nice piece of kit, what make is it?
unfortunately due to the uk laws, the car cant be over certain decibles and has to pass an mot and would therefore require all or most of that fitted.
shame really.
i might see if i can get rid of that middle section on mine.
does it really make a difference not having that many mufflers?
-
Is that a full mk2 16v system? How did you get all that for only 160?!

wrong! see my other post in this thread :roll:
-
The reason i can get it for £160 is because i run my own VW based company specialising in VW Polo's (I'm one of the owners of clubpolo.co.uk) I used my trade discount to get it from jetex - its 16v system, It's my family car and cant be too loud especially around here - the cops are a total nightmare - they keep pulling me over in my G40 due to the exhaust on it!
Should come down well under the 98dB for the MOT!

That's zagarusGTD's car, awesome sound! 100% straightpipe.
-

Very quiet until you get passed 3000rpm and then it starts to howl! Quick pick up of the turbo is still exactly as quick as it was without the backbox!
Next turn up the boost a bit!
-
Nice work, So did you end up leaving that middle section out then>?
Would be cool to note the differences woth it in and again without that mid section! I bet its nice to have a new full exhaust set up
Good job man...Looks clean all tucked away under there
-
So Montana have you done the devilish thing and stuck the GTD setup in a Mk1/2 Polo? The lack of brake servo was the only thing stopping me :mrgreen:
-
Good job, looks brilliant

Nope - but i'm pretty sure you could do it to a Mk3 Polo! (G40 shape!)
-
Kept all 3 silencers in it - its very quiet, but the boost picks up nice and quickly! Now to get the boost controller fitted and release a few more horses!
