VAC Non-M Headers/Exhaust

Has anyone ever installed these before?

http://store.vacmotorsports.com/e46-...age-p2936.aspx

Can't find any info about them or what they sound like but looks like a pretty sweet deal.

They're interesting.....

I think you could accomplish the same thing for Much less if you did this on your own using a muffler shop as your welding source.

If I were going to do this as a project, I'd buy a BB V1 header, a Magnaflow #94008 & get it welded up.

Not too fussed about cats as there is no emissions in Canada. BB I don't think ships to Canada any longer with their new distributor. At least according to their website they won't. Also, I messaged them via Facebook the other day and they read the message but never replied so who knows. I was thinking most likely just run the Schmiedmann Headers and buy the supersprint x-midpipe to either straight pipe or some muffler (undecided yet). Thoughts?

Hopefully Schmiedmann fixed their quality issues. My friend with an ESS Stage 2.5 330i got these, installed them but had a lot of trouble with them and ended up taking off shortly after.

Thoughts:

I'd buy these from Trader-Nas, these are what I've been running since 2010,....they were a Perfect fit. I'd also bolt up your stock OE cat-back & drive it for awhile to assess the situation.

Ships to Canada

Hmm, it just seems a bit controvesial installing Ebay headers before a so called "reputable" brand. Especially when the ebay ones are more expensive! Haha.

Like I said, I've been running them since 2010 & they were a perfect fit. Anthony was just some guy on E46F in the beginning that helped out with a few group buys. He then saw an opportunity in Brakes & Headers, so he started BimmerBrakes. I'd bet 99% that the BB & Trader-Nas headers come from the same Chinese factory, that would explain why they both have had such a good "fit" reputation.

Looks like a good deal. Nice 304 SS metal, I'm sure the fitment will be fine.

I don't understand the cats though. The bungs for the o2 sensors are in the headers lol. So the cats are pointless (if you're trying to pass emissions).

I would see if VAC sells just the headers alone. Just say you already have cats and a midpipe...

You're on the right track with the Supersprint x-pipe (section 1). The OD of the SS pipes are 54mm vs 50mm stock (if that). Try and keep that same "oversized" piping for the rest of the exhaust system. Supersprint also makes a section 2 resonator (again 54mm). Then finish off section 3 with a straight through muffler design (no baffles). Something like a dual in/out Magnaflow muffler (57mm or 2.25")

For Supersprint products, buy from Schmiedmann. They're significantly cheaper and their shipping prices are good.

Your a bit late to the punch! Haha. The reason I wanted cats was I am not a huge fan of rasp. Sounds like a Honda IMO. Anyways, ended up buying a set of new bb headers for a $225 shipped to Canada and am just looking for a Rogue DMS to complete my setup now.

Whoops lol.
The DMS is a great exhaust. 57mm piping which is good. You'll need a resonator placed somewhere though. It's loud with headers!

Haha all good! Yeah that's what I was thinking. Probably just get some simple magma flow ones or something installed by the shop!
