Hi All,

I had some pretty bad drone after installing a Magnaflow muffler on my detail addict custom made exhaust. The exhaust is a piece of art. Leo @ detailaddict did a great job designing it. It increases pipe diameter from 2.25" to 2.5" and from 2.5" to 3". It also deletes cats and resonator. I had Leo do a m3 quad rear section with a Magnaflow. Muffler was my choice and it ended up droning from 2k to 2.5k. This was no good for me and my daughter.

I started looking into options and given the piping and sections I had available I went with a Flowmaster HP2 and a Dynomax VT4 inline. Both are designed to lower sound but the Dynomax guarantees drone free operation.

Anyways, my search for shops that Tig Weld in the GVA led me to Carline in Richmond, BC and Muffler Tech in Port Moody. Engotski mentioned Evolution Auto Performance. I looked up some of their work on Revscene and it looked great. I saw some of their work first hand at their shop and some of it was beautiful. Their welding of stainless and aluminum was very nice. Also, @ $75/hr, their price was good too.

Kevin, the store owner did the work on my car, but another tech there, his name slips my mind did some beautiful work too. I saw a custom piece he had created and it looked like a machine had welded it. Quality. They have a dyno too. It's not a dynojet or a mustang dyno. Forgot what kind. Hopefully I will dyno my car before tune and primary cat delete to see what type of gains I can get.

Here are some pics of after and a vid of the sound before I swapped out mufflers. The sound now is almost quiet as stock at low revs. When I get 2.5k or so above it becomes audible. I feel the car pull harder after this exhaust. It is more fun to drive.

Hey man. Rmb me? We met in no1. I'm the guy who has a straight pipe on my black e92. How much did u pay for it in total?

It's hard to tell what it sounds like because the audio is so bad in the video . Maybe take some outside video of the exhaust it might give us a better chance to hear the custom exhaust . Piping looks awesome!!!

took 3.5 hours so a little over $350 with the little bits of bends and such they used.

[mapleridge]

just realized this is in the wrong forum. If one of the mods can move it to the Canada section, I would appreciate it.

Glad it worked out bro! Ask for a group dyno rate im in!!

On the side note, my car got fukin broken into last night! Body shop it goes again! $300 down the drain

[mapleridge]

I will definitely organize a group dyno if members are down. Thanks for the advice on the shop. As for the break in. I suggest a cctv camera and a good rifle. What did they take?

Awesome! They charged u way much less than what drivehard for mine. Mine was like only straight pipe. Drivehard ripped me off! And the job was so fuck up and kept saying that they had tried their best for adjusting the position of the tips. Due to ur car muffler position, that's it and it will be off no matter what! Fuck! I was so mad, but we r kind of knowing each other well, so I held my anger!

No and yes have the bmw pe. Im talking about dyno...

You definitely need a better video. Too be honest, it this video really kills the sounds of the exhaust and makes it sound weird.
Glad the drone problem is fixed.

I know the video sucked. I have no skills with placement and such. It was just loud at all times and deafening at 2k to 2.5k. It made your ears hurt. Since I changed two mufflers at once I can't tell but the dynomax has an internal valve that is supposed to kill drone and fully open at full throttle. I think that is what keeps it quiet but minimal drone is there still in the same range. It sounds pretty awesome aside from that now. Deep and those back fire sounds when in Ds mode.
