Excited to see where this goes. I can tell you that exhaust will be very hard I live with on the street. Think horrible drone at cruising speeds that gives you a headache in minutes. For ultimate power however it's hard to beat. On a track only car absolutely. On the street I wouldn't do it.

Are you building for N/A or F/I?

N/A. Thought about F/I, but decided not to for this project.

As for the exhaust being loud, I know this, but I think I have a solution. Bimmerworld/Turner provides two pipes for the midsection (one resonated pipe and one straight pipe). I plan to use the straight pipe and weld in a Magnaflow muffler.


Two or three concerns with this exhaust though..
1) The Y-Pipe. Is it too far down stream? From what I understand, it's suppose to be as close to the headers as possible. I'm sure they did their homework on this though. The collector looks well designed.

2) The Y-Pipe is suppose to be used with e36 manifolds...but no way in hell am I taking off the Technik Gen 3's. So I'll have to cut some piping off the end of the Y piece and weld on new Flanges to mate up to the Technik's.
The thing is, where can I source them from? I'd like to avoid buying a used exhaust just to cut those off.

3) Weld on (2) 3" tips at the end of the exhaust just to keep it clean.
Similar to this:

Stav,

I can't tell, have you bought this exhaust yet ?

I wouldn't then. There are to many points that you yourself have brought up, & all are valid.

1) At roughly $900 plus dollars, You shouldn't need to re-design it.

2) You're 100% correct, the Y pipe should be as close to the header flange as possible.

3) As Jared already said, I'm confident you'll be trying to fix a droning problem within weeks of running them.


On a side note, there's a brand new Burns Y pipe for sale right now from someone that's been sitting on one for quite awhile at ~$165.

The money will be spent regardless, honestly.

Yes I need to tinker with it a bit, but you should know me by now Rob! I like that stuff. Cutting that extra foot or so of piping and attaching new flanges is easy, but where do I get them?


The extra muffler and exhaust tips would need to be done regardless if I use this system or not. Again, I think the nice thing is that they (BW & Turner) provide that extra straight pipe I could use to weld in a muffler.

IMO, it's just easier to buy the system, tweak a few small things, and be done. Not to mention the spec exhaust was actually tested and most close in relation to their WC cars.
(Edit)

Here's some other stuff I've been messing with on the side. Btw nothing really finished yet, still waiting on the Recaros so I can drive the car..


Disa Valve Repair Kit (Gary's engineering is impressive to say the least) Btw that oem seal eventually came off, but it's a PIA!



OEM Pin going strong for 120k!


Next day, cleaned out the TB & ICV. STETT Intake boots in (possibly selling them idk)








And YES, I reverted back to the BMW Performance box (from Dinan 3.5" CF). I had to on this one. The facelift coupe headlights prevent a tube intake from being practical. I'm gonna give this a go. The design is perfect. Also nice to have both brake ducts fuctional.







Might run this to brake duct.









OEM Silver Cube Trim(new darker version). Would look better with the Recaros..

A friend of mine has the Dinan cai. I was really surprised at the crap design. Would be better off cutting a hole in the front of the oem box

The BMW Performance intake seems very well designed IMO. With the three different inlets pulling fresh air from the front of the car, I can't see how any other design could yield any better results at all. Maybe only if you ever were to somehow pull enough CFM to outflow that filter in there, but you'd probably need like a F5 tornado in your engine bay to do that...

Very Clean Install looks much better than OEM

My humble opinion about the exhaust,

1 3" V band Collars....$39
2 3" V band w/clamps.$90
Burn Stainless Y pipe..$165
Tips.........................Too many on market to list
Muffler.....................Too many on market to list
Resonator.................$55
Stainless Stock..........$126 (could more than likely get it cheaper locally)

I would almost bet money you could print this out, take it to a local exhaust shop, they would match the prices or would be cheaper. Then you wouldn't have to do any of the sourcing.

$475 shipped without a muffler/tips/labor. The B/W exhaust is $1200 shipped + labor for changes

You will have a few bucks into muffler/tips. If you are already planning on modifying the BW exhaust why not make more power, get what you want, have no left over parts and save money? Just my 2cents

OE intake boots: Pros: best flow cons: will need replaced due to material cracking over time.
Stett intake boots: Pros: will likely never need to be replaced Cons: air flow isn't optimal

I put together a shopping cart on jegs.com for you: This order includes 8 feet of stainless

This is how the e46 m3 race Y-pipe is done, You want to mimic this as much as possible. Above is the cheapest/best way to do it.

I don't know anymore about the Y pipe placement. The only way to know for sure is to dyno it.

good point just throw a x pipe on the end of your exhaust. Then you can have a y pipe and tips

The Stett Boots are worth a few HP, and My Dinan intake works the same way as what you are trying to make.

I can tell you that the location of the y pipe in the BW exhaust is probably not optimal for a car with headers. If they did their research, (and I'm sure they did) they would have placed the y-pipe optimally to scavenge from the stock m52 manifolds. Likely the long different length pipes leading to the y are tuned specifically for that. Different header's change all that.

Their Y pipe is for the M52 stock manifolds, and ends up with the Y pipe located near the rear of the transmission. In fact, I've seen a LOT of Y pipes end up in that position.

The engine seems really sensitive to the exhaust. Perhaps the exhaust side of the head is not working well (MM hardly do anything to the exhaust side for their head, cam etc due to emission reasons) or perhaps that it is overcammed and the ‘right’ exhaust helps counter some of the side effects/problems ….

Run 1 to run 2 was a catalytic converter change out where the new cats were moved closer and side by side as opposed to staggered
Run1



Run 2



Further investigation into this never found out what happened. I even put back a similar set of cats and used photos to position them as close to where they were but it didn’t do squat. Perhaps it was something to do with the dyno setup on Run1 and as such it is not real or there was another issue at play…..

Run 2 to run 3 was a x-pipe relocated closer to the engine
Exhaust from run 2


Exhaust from run 3 notice the x-pipe is closer to the engine



Run 3 to run 4 was a cam timing change (advanced 8 degrees). i did a cam belt change at the same time and thought maybe the timing shifted a few degrees. while i found good gains the shape of the torque curves shows that this was not the problem. the real problem is the relocation of the x-pipe.
