Just bought my 1st VR6

Hey mike, you got a vr6, one you aint told us bout.....

If you get a 6branch mani you have gotta either uprate you mounts or get some flexi in your exhaust preferably at the base of the 6 branch....if not then in the decat (which i got from dubpower).

If you dont then your 6 branch will eventually crack, which happened to mine.

Alot of people advise heat wrapping them as they get bloomin hot and can melt stuff aswell as cracking also, although i never had a problem.

Powerflow will fit flexi between the cat/decat and manifold....

And as for VR6, there is hints alll over this forum... Work it out yourself! haha

Never looked under one of these before so not sure but does the standard exhaust come in 3 sections? Manifold, pipe with cat, back box? I have seen the hotuning manifold and straight through pipe? So does this mean i then just have to get a backbox and does eliminating the cat make it sound toooo loud?

[Mikester]

You have the manifold, then a little bit of pipe to the cat, then after the cat you have more pipe going to the middle box or silencer then more pipe going backwards, over the axel and out to the back box.

Removing the cat wont make it much louder, its removing or changing the middle and back box that changes the noise.

[Richard Andrews]

so it is possible to have a straight through pipe starting at the bottom of the manifold all the way to the back box, thus eliminating the cat and silencer? So manifold, pipe, back box (3 pieces) ?

yes u can, i had this on my 8v gti, was very loud!!!!!!!

[Richard Andrews]

Can I buy the straight through pipe ready made from anywhere that I can just bolt straight onto the manifold at one end and onto the back box at the other end? Was thinking hotuning manifold, scorp or reamus back box.

[Mikester]

I bought a ready made one, and it didnt go over the axel very well and knocked when i lowered it. So i got a custom straight through made, and has given no problems.

When i do this again im going to have a decat pipe, and maybe a miltek back box, then just get a custom exhaust place to fit a custom pipe between the 2, so that u dont get any issues.

When you fit a 6 branch, it bolts straight to the cat (or decat) and then come the rest of your exhaust. My vr had a straight pipe from the manifold all the way to the back box and sounded wounderful, although a little boomy at around 3000rpm but suprisingly quite above that while cruising down the motorway.

So apart from the wheels and suspension was thinking:

Hotuning decat pip
Hotuning Manifol
BMC CDA Induction Kit

But not sure about back box? That REAMUS one on youtube sounds mental?

Euro Performance sell a few different brands, any suggestions?

I added to my vr6 a induction kit
powerflow straight through centre section
magnex twin backbox and made 6bhp
from my last rolling road whent from 176bhp to 182bhp
looking at removing the cat now n a racing tubular manifold
