the healthy sound of a dump/front pipe?

[druzilla32]

hey guys,

i installed my dump/front pipe and hiflo cat last night..

How is it meant to sound, cuz mine sounds like a v8 at the moment... the dump is louder then the rest of my exhaust?

is it meant to be like this?

When my exhaust was stock and I installed a front dump and hi-flow cat the sound changed very little.

I could now here a high pitched sound related to the turbo but that was all.

You may have an exhaust leak.

yer i found a leak...

The bracket for the heat sheild makes the contact between the dump and turbo realy uneaven...

I have exhaust wrap over the dump. My question is can i go without the heatsheild? does it realy block that much heat? I can just mount the wires up a bit higher near the abs, will they melt or anything?

2. Is the wire/connection that goes in the top of the dump my knock sensor?

Hi druzilla32, replace the heat shield, it make a lot of differecne tothe underbonnet temperature. We even exhaust wrap the heat shield for better insulation.

[druzilla32]

do you know a way of mounting the heat shield without using the bracket that goes between the dump and turbo... Cuz it doesnt do up any tighter and there is still a gap cuz its uneven.. I just put it togethor then without the shield and i was just going to put exhaust wrap over the connection and wires that come from the top of the dump... But if it makes a big difference i would like to put the shield back on....I dont know how to mount it tho.... + i polished it last night

If I read you correctly, you've stuck the heat shield bracket BETWEEN the turbo and the dump. Right?

It goes OUTSIDE the flange ie dump mounts up to turbo, and bracket sits on dump, then put bolts thru bracket and dump into turbo.

The wire / connection is the O2 sensor.

2. Is the wire/connection that goes in the top of the dump my knock sensor?

Nope. The knock sensors are on the inlet side of the block underneath the inlet manifold.

The sensor in the top of your dump pipe is the O2 sensor...

Can't help with the mounting sorry

GAWD IM A DUM SH1T!

haha.. i cant beleive i didnt do that..

thanks mate

[druzilla32]

in the attached image.. the green ones are the bolts that i have done up tight.. the 2 red ones i cant do up cuz there is no room to tighten them cus the spanner or whatever else i use hits the dump and cant be turned... how could i tighten these up? I cant feel any air or hear any leak from it...

ok image didnt upload... I have the four outside ones done.. The other 2 are impossible to get to.

I havent realy tested it out yet.. i have only gone to .4bar.. Should i turn boost down or anything like that first... i only have a bleed running .8 atm... this was before the pipe/cat was put on... Should i be listing to anything while i am testing it?

thanks

lol man don't be a bum do it properly

[Skyrine-Dave]

use a spanner straight up and down so it grips the bolt, then use a screw driver in the eyelet to turn it... thats how i got some of my bolts done up
