Title: GTI Exhaust > 1.6 Driver.
Post by: rich_4130 on 09 March 2007, 19:13

Hey, got a Gti exhaust to go on my driver, will it go straight on, are the I.D of each section the same? or will I need some sort of adapter? have the front silencer back.

Also, anybody got any tips on the fitting?

Thanks

Rich

well i was told that a 8v gti manifold would go straight on. so i think you will need to get a gti manifold as well.

It wont fit straight on, the 1.6 system is smaller than the GTI system. You have several options:
1. fit 1.8 carb downpipe, this will mate to the original manifold, and has a bigger end which fits the gti front silencer
2. fit GTI manifold & downpipe
3. get an adaptor made up between your existing downpipe & the front silencer

Option 2 will give you the best performance, but is also the most tricky/risky.  You may end up shearing off one of the manifold studs, I did this on my driver and I had to drill it out & re-tap.

u say option 2 is the best performance, but what risks are envolved? is it just the bolts sheering? or are there other risks?

If a bolt shears, then a proper fix would be neccasary for a decent seal. Depending on which bolt shears and where, ie, in the head or the manifold to exhaust connection, access is very limited and head removal may be the only option. If you are going to go down this route, take the car off the road for a day or two before doing the job and completely soak the bolts and studs in penetrating oil. Keep applying the oil every few hours and let the oil do its job. BUT, there are no guarrantees.

WOT 'APPENED THERE THEN????????????? :huh:

shearing a bolt in the head is the worst case scenario, if that happens its head off time.

I forgot to add that to get the new downpipe in you'll have to either take the head off, pull the engine out or drop the subframe!

this job seems to be getting bigegr and bigger, with more risks than i initally thought, may just stick with my standard exhaust!

Post by: vw-bob on 13 March 2007, 19:10

i dont just want the back box i want the whole system, so going to have to find a way to do this with out the risk of sheering off bolts

Depends on how adventurous (?) you are. If you are up to the challenge, acheive what you want to. Expect a bolt to break and be prepared for the extra work. Its good experience and you end up with what you want. There is a wealth of information and clever clogs on this site to help you through if the worst comes to the worst. Go for it!! :smiley:

The easiest & safest option is #3, fit the whole system and mate it to your 1.6 downpipe with an adaptor.
The next hardest is option #1 you'll have to pull the engine or drop the subframe to get the 1.8 carb downpipe in, but no nuts/studs to worry about.

well i will have to think about what route to take, just depends on what i feel i am capable of doing

wel im sure that i would be able to do the work, but its just wether i can afford to take the car off the road for a while, due to travelling to work etc, and the limited tools that i have, just my dads tool kit.

Ah wow, not checked this in a while.

Yeah I got the verniers out, and found out the o.d of the gti system is like 49mm, and the driver is like 42mm, no amount of paste is gonna seal that!

Getting my dad to machine up an adapter sleeve, I can fit the rest of the system when I get round to fitting a gti head.

Cheers.
