Many people have asked me about my quad setup and how i did it so i figured id write a little something up.

First let me say this was all the work of John@CVT Muffler in Houston, Tx. He's the artist behind this one.

On our n52 cars, there is a metal box on the right side behind the bumper that is in the way of being able to run a pipe comfortably or without a 90 degree bend. What needs to be done is the following.

#1) Build a Bracket (basically a metal plate) and weld it onto the metal box
#2) Measure out the tips (for how much they stick out and stagger) and cut them accordingly so that they have a straight back end. Weld them to the bracket.
#3) Cut the tips off your other muffler is necessary and have new piping/tips welded onto the muffler on the other side to match the right side.
#4) You will likely want to spraypaint the bracket black so that it almost dissapears to the naked eye from more than a foot away.

Here are some pics. Feel free to ask any questions you may have.

I paid $100 for labor and they are Dimisa 3.5'' Black Powdercoated Tips.

Can we remove those compartments underneath and install another exhaust? I think it's doable.

[Gjm127]

i thought of doing this but then I thought... it would look horrible in winter!

So these then are a fake version of something that is sort of fake to start with? That is lame.

Hate all you want. Just trying to help out the n52 community.

[tshoww]

+1 for making it your own

[LocDawgg]

BTW he contributed to the community. You should be hating on the Lexus IS-F those quads are fake as well.

imo its a good setup.
for the looks of it
And its a good balance between performance vrs looks
plus, OP managed come up with a solution of not losing much low end torque performance...
to me spliting n52 to quads is even more of a fail due to not having torque at all LOL i mean minivan will probably keep up with it on exit power.

i disagree. i think for the most part e90 has supportive members but there are for sure a good number of members in e90 commuinty who's maturity level that are
unfortunately they're also annoying loud group of kids.

5-6 series community has much less noise.

ahahahaha, wow... fake quads... clever, but a big no-no IMO...

[Blindside_137]

hmmm thanks for posting.

Is it possible to get 335 quad type spacing? closer to the center?

I want to do quads at some point and don't want them spaced away so far from one another, on 335 quad they seem to be just a bit closer (but still further away from each other compared to m3 quad spacing)

Would this be possible with your method?

I have been thinking I would just try to do some type of custom piping but not sure how to navigate around that big box. I know guys have done full quads before with the closer spacing on 328s, I guess I'll have to ask them.

Thanks for pictures, those tips look amazing! and the car

[N0OS3]

please don't do what the OP did if you're going to do quad exhaust... PLEASE. Might as well throw spinner hubcaps on your car too...

btw... ramirez330i: if you spent $100 in labor to do this, why not save another $80 and just epoxy those suckers on there? ... just as effective with JBWeld i would assume...

I really don't understand the fascination with quad tips, so much that folks will slap on bootleg tips (expensive tips I might add which makes it even more ironic) to their B M W.
