2011 M3 e92 Full bolt-on

[andrewkd16]

I have a 2011 e92 M3 with 50k miles. Bought the car stock and since then I have put volk te37 and dropped it on kw sleeve over kit. Stance is perfect imo but now I am going to upgrade motor and I have some questions if this setup would be good. I am trying to stay within low to high 7k here is what I'm looking at buying and hoping it will go good:

-akrapovic rear section

-afe stage II intake

-turner test pipes

-x pipe maybe meisterschaft....

-Dinan or AA or afe or MS pulley kit can't decide on which

-bpm tune and DCT reflash


If anyone has any setup like this can you shed some light let me know if this setup will have good gains. I am shooting for 400rwhp. I do not want to supercharge or any fi. I want all v8 motor. If anyone else has suggestions on what else I could do please let me know I'll be buying this soon and I am an Atlanta local and I need to find a good shop if there is one here in GA.

Skip the intake, just get a drop in filter. Same HP gains far less cash.
Far as a tune goes I would got with BPM, tons of options great gains and Mike is a great guy to work with, all you need is a laptop and its just plug and play and he will talk you through it on the phone.

If you getting akropovic full exhaust you will not need test pipes as that will have an x-pipe aready. Now if you only getting the axle back/slip on then yes test pipe be much cheaper than an x-pipe.

[andrewkd16]

Ah so you cant have test pipes with a full akropovic? I was wanting to go cat less that's why I said full thinking I could rid or both cats. So it's either test pipes and axle back or xpipe and axle back.? Can't have test pipe then xpipe to axle back then?

[squartus]

You can get the race version which deletes the catalytic converters and resonators, that costs another 1k which is funny since it uses less materials.

Which brings the full system up to $7,500 if bought new which is silly.
You could get the rear section and buy a race x pipe from another company and save a few grand, usually can find one used here on the forums.
If you got test pipes with x pipe you would have to cut out a section of you x pipe to install it. Which if you simply got a race x pipe you would have no cats to remove in the first place.

A credit card with an 8k limit isn't free money. I only put stuff on a credit card it I can pay it off at the end of the month. Something tells me you won't be able to pay the bill at the end of the month. I could be wrong.

[andrewkd16]

Changed it up so maybe it will sound better just looking to keep price around something I can afford 7-8k

Here's some information on our software which would compliment your car nicely:

Congrats on the new car and enjoy in good health!

[andrewkd16]

Thanks Mike makes an easy decision on tune. I'll be contacting you on parts I purchase and see about that stage 2 tune maybe that DCT tune as well

[pbonsalb]

Akra eats up a lot of the budget. I would skip it. Buy a full x-pipe that eliminates both sets of cats. There are a few reasonably priced ones to choose from. I recommend using one with 2 resonators (Dinan and Borla use 4 and some are available with none). Figure on $1500. Buy a used MS or Dinan intake for $300-$600. A rear exhaust like the Megan is about $600. A tune is about $1000; not sure about the DCT reflash. A pulley is about $250 used. $4k for pretty much equivalent parts is much more bang for the buck. Cars with this set of mods typically does anywhere from 375 to 400 rwhp. Very, very, very, very few cars have broken the 400 rwhp barrier SAE on a Dynojet. For the reality check, look at the dyno database. Try Technica Motorsports in the Atlanta area.

[andrewkd16]

Thanks I'll look into that x pipe and check dynos

Don't waste your money on an overpriced exhaust. It literally provides nothing over any of the other exhausts and you won't gain much from it either. If your budget is in the 8k range, I'd buy a supercharger kit before spending all that on exhaust and intake, etc. If you want an exhaust badly, I'd follow the previous guy's advice.

Yep, agreed.

FWIW I made 720whp with a ESS Catless X-pipe, on the stock Exhaust/Muffler with the VT3, so the stock muffler flows plenty.

[andrewkd16]

well my mind is made I have decided to get the Megan exhaust and I've already ordered the Turner test pipes K&N drop in filter and Dinan pulley kit. I have also decided to supercharge it that's why I didn't go with the full intake by AFE. because if I'm right a supercharger kit will eliminate my air box correct? The Dinan pulley kit will work with ESS supercharger kitright? Or does ESS supply a new set of pulleys? anyone know the best place to buy the Megan cat back with burnt tips the cheapest I found was on eBay but eBay scares me sometimes. I'm going to wait to tune it because I know when I super charge itI will have to use the ESS tune. I'll probably search for an X pipe thats catlessany suggestions since I have the Turner test pipes and will be going with Megan exhaust?

Dont' do the pulley kit because it will affect the boost on the ESS kit. FWIW, ESS makes a nice X pipe. No need for the Filter because the ESS kit comes with a new intake setup.

[andrewkd16]

Ok well I got the filter it was only 80$ so it's OK till I order kit. Plus I got pulley kit I'll see if I can return it or something

The pulley kit will need to be uninstalled in case you missed it. ebay is generally the best place to pick up the Megan exhaust. I avoided using an Xpipe as the test pipes do the bulk of the work. The little cats and resonators in the stock x-pipe aren't very restrictive. But they do keep the sound at a reasonable volume.

I bought a used Akrapovic axle back, paired it with ACM test pipes, BPM tune and AA drop in filter... I've never dynoed the car so I can't help you with Hp #s but I am happy with my setup.

My advice is to buy your exhaust used, they are expensive for this car, but if you buy a titanium one, you should be able to resale of for very near what you pay for it. It's not like it is going to wear out or something.

Technically you could use the pulley kit, but you would have to install a smaller supercharger pulley to make up for the loss in psi, and you'd also have to source a shorter belt, not worth it, just send the pulley kit back or sell it.

So you would say no to going catless? ill check a sound clip to see. but I figured catless would squeeze every bit of power out of it.

Using test pipes eliminates the primary cats, but leaves the secondary cats. The secondary cats have virtually no restriction associated with them. Most racing x-pipes do not include primary or secondary cats.

Test pipes are cheaper, buying an x-pipe makes it easier to switch back and forth and an x-pipe is easier to sell and go back to stock if need be. Only you can decide which is the correct route for you.
