Talking Custom N52 Quad Exhaust + M3 Rear: Pics & Video

Hey guys,

I've been less than happy with the stock exhaust and couldn't in good conscience go with an AA "exhaust" or fork over $1k for a PE. So, I found a good shop in Washington, DC to fabricate me a custom one. Very happy with the results.

We took out the secondary cat and resonator. Used two glasspack mufflers. There was a great deal of pipe bending, welding, and on the fly problem solving but it got done.

The biggest hurdle was the storage box in the trunk, they had to do a very significant bend to essentially wrap from the left to the right for the quad tips.

Anyhow - enough talking - check this out!

Install completed

The exhaust is awesome loud between 1-2k RPMs, quiet between 2-3, then loud again. Some backfire/crackling on downshifts, guessing the engine is getting used to the exhaust still. Not a lot of "drone" since I tend to stick between 2-3k RPMs. This thing on startup is very sexy sounding - deep growl. I'll take another video of that soon enough.

SCM

I drive a lot of city miles, so I haven't had time to reset my stats and see what they are after putting on this exhaust.

Thanks brother! It is definitely a big change for me, I've found myself upon start up wondering (is that my f$#king car?) and at stoplights wondering who has a beast at the stoplight. The upside is I can now have my car growl at people when I'm irritated in city traffic - I scared someone last night doing exactly that.

Can anyone give me the name of some good exhaust tips that will lower the sound on my 2008 328i coupe?

The work is great, but IMO the M3 bumper just looks so out of place.

But I'm glad you like it, it came out very well.

Tips aren't going to change the sound. You can remove your stock muffler and bolt/weld on a MagnaFlow for under $200 at most shops

Sounds great but that looks like it would lose HP with that crazy bend as well as a quad setup on these n52 engines has always lost power. Any before vs after dynos?

Unfortunately no before/after dynos, I haven't done one with my car as of yet and would have to find an AWD dyno as well.

My initial feeling is that it is more responsive on the throttle and the middle of the throttle band feels stronger. This is all subjective though.

I don't see how you lose power removing the final rear muffler only. That thing also weighs nearly 60 pounds

Probably the lights. I have blacklines en route. The lights throw me off currently.
