Modifying the Spec E46 Exhaust on the Supercharged ZHP
Can we tame the beast?
The Spec E46 exhaust system was developed by Magnaflow in partnership with bimmerworld for the Spec E46 racing class. It uses E36 headers, a specially designed y-pipe into a single 3" mandral bent pipe. The exhaust includes a Magnaflow resonator (race muffler) up front, and a 14x9 Magnaflow muffler in the rear.
The Spec E46 exhaust is a bit loud for my tastes, so I set out to bring down the db's without compromising the high-flow characteristics of this exhaust design. I chose the Borla 40575 XR-1 Multicore muffler to replace the Magnaflow resonator, and added the Borla 400939 resonator into the mid-section.
This video compares the sound tone and levels of the standard Magnaflow Spec E46 resonated exhaust configuration with my modifications incorporating the Borla components. While not easy to detect due to the GoPro's automatic volume level adjustments during recording, the Borla configuration is notably quieter.
Car is a BMW 330i ZHP with full Spec E46 exhaust setup (and ESS TS2 supercharger, LSD, etc).
Video taken using the same GoPro Session 4 on the same stretch of highway. Video for each exhaust system was taken approximately 2 weeks apart following the same "script".

Hello, do you have Instagram?
Hi, is it full exhaust system or cat back? Borla sounds amazing
Hi, these are both cat back systems
Just did this. It was my Father’s Day present. Freaking awesome
I'm doing this in june! I'm driving the GT4RS I'm super excited
Enjoy it! I'd love a shot at the gt4rs.
this is the amazing upgrade of the predecessor Torsen LSD & i think this is most precise & reliable LSD
The Borla sounds amazing. Thanks for the video
I know this was from a while ago but would love to know how the wavetrac handles dry / ice when you hit it on a high speed turn. Does it initiate over or under steer depending on whether the outside or inside wheel hits ice first?
This is all i needed to know to fit one on my 140i 👍🏽
What a nice video, very recognizable! Loving the E46
the only good ones for bad weather is the CLUTCH type and WAVETRAC. so being that you "saw no difference" sadly, is the whole point of the Wavetrac vs. Queef whatever one. Clutch is really good actually for most any condition, just not the best track cornering times compared to queeaf whatever. However, you are demonstrating here that the Wavetrac is superior to the quoef one as it behaves just like a clutch-type diff in ice and snow. Which is why it's a must upgrade for daily driving sports cars. I am getting one for my new 2023/4 JCW mini hardtop (wavetrac)
One wheel on ice, the diff is doing just what it is supposed to do... the car moves forward and straight up the slope. With both wheels on ice it acts like any diff. Both wheel spin, but if one finds traction it will then move straight forward. I have built many rears for race cars, street cars and off road. WaveTrac has proven best in almost all circumstances.
great to know! i am going to add one to a brand new Mini JCW 3 door this fall. wavetrac seems most sensible.
I was considering a wavetrack but eyeballing an OS Giken Superlock now. (BMW 650i e63).
We use Okta at Ally. Where is my track day! ;)
Borla for the WIN!
I had a ton of cars never a BMW and Im just thinking about buying one E36 or E46 for a daily driver just going to work and take my kids to school (10min drive) and I need it for a drift project on the side but not now I mean I want to keep building it until is done in a close future maybe 5-8 years, should I buy one of this BMW or should I get another car? Are this BMWs reliable and actually good cars or just a headache!?? Really need some help!!!
Thanks for your time and dedication to makes this video!!!
No question, Borla is much better
this wavetrack diff probably isn't working right because I've seen the parts disassembled. You'd have to wear the preload springs and the sliding lock hump completely in order to get THIS result. And since it's all submerged in oil, I don't understand how you could do that. This looks like a completely open diff.
impressive this guy kept swapping out his exhausts every other take... how long it must have taken in real time!! borla sounds great.
i don’t know if this is a joke or not
I am looking for an lsd for my fwd honda to improve offroad traction ie when one wheel is in the air. I am used to my old truck lsd which locked for a quarter turn any time a wheel spun a quarter. I heard the wavetrac worked in zero traction but this video clearly shows it doesn't.
it does. ice and he has improper tires. he has all season random tires not ice and snow. Mud is much higher of a friction coefficient than ice which is almost 0 under pressure. Wavetrac will get your job done in the mud for 2 wheel drive.
Yes WaveTrac surprised me that with one wheel on tar the car still didn't launch.... Would love to see a locked/welded diff videoed in same situation.
@@michaely6665Its not hard to understand how a welded diff would have behaved in the same situation
Looks like it works the same as any of them.
That does not look like a limited slip diff at all. I thought it was supposed to put power to the wheel with the traction.... It clearly wasn't. Its acting like an open diff.....
Borla 🎉
100% Borla
With Quaife ATB you would gently pull the handbrake lever (if U got one... U should).
Was there any rasp in the borla?
Magnaflow sounds so damn good
What was it
It was the crappy tune from ESS. I retuned it myself from scratch and it's smooth as butter now. I can only assume they used a poor strategy without considering how the DME controls throttle in relation to the intake manifold model and other parameters.
Borla
same
Definitely going with Borla for my e46..
The exhaust note of these engines grows on me by the day.
This is how all exhaust sound videos should be like... I'd go for the Borla as it has a nicer tone which makes the engine sound better...
Hey Ryan! Did you ever upgrade the struts on your ZHP suspension?
Hey, yeah I did. I upgraded to MCS coilovers with hyperco springs, and a Turner front sway bar. Car is super flat in turns and super fun to drive. Although it might be a bit too stiff on the street.
@@rkneeshaw nice!! Retained stock rear sway bar? Did you ever “reinforce” your sway bar mounts? Heard that they snap under too much pressure with stiffer setups
@@YuStudios yes I did, had those done back in the day with the rear subframe reinforcements, just in case
there aren't many things that sound as nice as a BMW straight-six imo
Bmw straight six and VW VR6 for me, just pure harmony
Magnaflow sound reminds me of an E30 BMW 3 Series though I think I like the Borla more.
Evey engine deserves a good set of exhaust headers
I have had magnaflow #16533 on my ‘05 zhp 330ci. I used this as a guide, and compared both online. Magnaflow catback $1200, borla 1400 ish. The magnaflow has a: -2.5 inch bigger diameter vs stock/borla (2inch) -X pipe (vs no xpipe) in borla/stock -Also at time around xmas last year borla would’ve taken months to ship, magnaflow week till i got it - cheaper with more stuff, i also thought sounded better. Next mod is catless active autowork headers :) can’t wait
i’m thinking about getting a 16533 Magnaflow on my 325ci. Going to swap a B30 motor into it
@@thetonyhope good choice, and smart swapping the b30 in. I would say after about 14k miles on the exhaust, not the loudest in the world. At idle and warmed up, you can hear it but nothing crazy, and it makes most of it’s noise around 3k+ or with load (like going uphill in wrong gear). If you get headers I would assume it would be plenty loud, but I will say a good sport exhaust, not a crazy crazy exhaust.
I think It sounds better than a M3 E46 . Sounds more like a 2jz or rb
Are the resonators removed or still present?
Still present in both systems
Borla sounds much more like a racing i6 and not tin can
The magnaflow doesn’t sound like a tin can :( i have the magnaflow, it was $200 cheaper which I didn’t care about but it had an x-pipe, 2.5 vs 2 inch exhaust diameter compared to stock and borla, and the borla wasn’t avaliable for over 8 months when I was shopping. You’re paying more money for less stuff given. I don’t have headers yet :( but one day I will. It sounds great, not a tin can. Biggest thing with an L-6 and and x pipe is rasp, rasp, rasp, im gonna step on the rasp. With catless headers I can’t fathom the rasp above 4k, but still want them as those actually give performance gains than just a lil catback.
One of the most informative and clear exhaust videos on this site.
This is definitely the best comparison video i’ve ever seen on youtube
Ryan hello, i am trying to contact you, to find out which Headers did you put on your ZHP e46?
Hello, these were super Sprint replica headers, commonly known as ebay headers
Little raspy to be a Magnaflow..
Headers prob make it raspy
which ebay headers did you get???
great car, was wondering if you had the wavetrac before you went forced induction. have zhp myself and an lsd feels like my next big mod and curious if you had any time with it when the car was NA.
I did, wavetrac was something I did in prep for FI. LSD is a must have, great mod
Deffi Borla
Maybe the BMW doesn't really have a Wavetrac?
No, it 100% has a wavetrac installed.
