Dump pipe replacement (the best way?)

[dabigbolf]

hey,

just wondering whats the best way to get the stock turbo dump pipe replaced, and with what design.

whats most effective. Is connecting the wastegate pipe 30cm from the turbo down the exhaust the best way.

what pipe size diamtere, of the dump, and rejoining pipe is best.

Getting one made up with front pipe.

I have heard of the V-brand dump pipes, are they any good.

they are a 3 inch dump off the turbo, with no rejoining.

cheers

if anyone is selling a second hand one, i'd be interested too.

Hi bolf, good to see you geting on with it, suggestions follow your questions.........

Is connecting the wastegate pipe 30cm from the turbo down the exhaust the best way.

**More like 40 cm, but yep that's the best compromise. Obviously keeping it completely separate with its own muffler is better, but heavy and expensive.

what pipe size diamtere, of the dump, and rejoining pipe is best.

**we use 2.5" off the turbine housing (that's its size, so no choice really) quickly rising to 3" then 3.5" once the wastegate pipe joins.

Getting one made up with front pipe.

**good, saves weight and excess joints to leak, we have one piece to end of cat (ie; no cat) saves more weight and another joint.

I have heard of the V-brand dump pipes, are they any good.

**Sorry, never heard of them

they are a 3 inch dump off the turbo, with no rejoining.

**That's a screamer, very very noisy when wastegate opens.

Hope that helps

hey cheers,

yeah had a screamer pipe decided to sell it, would have been to much trouble with cops.

one piece from the turbo to cat might be the best option.

cheers.

after reading the post of boostd who ran 12.9 with the stock turbs, i am excited. 213rwkw, is awesome. In my car, that could even go close to 12,'s. well maybe not . but sounds good on paper.

should have car started by this weekend.

and then send off for cooler setup.

going the front plenum, seems to be the best option at the moment, and i'll go the 2.5 inch piping.

will keep ya updated.

oh shutting the bonnet, is another problem.

DOH. no need for partition near air filter i guess. all open to atmosphere. cool air ats its best.
