ER Downpipes w/ Stock Exhaust + JB4 Review

[stealth-twntrbo]

Just installed my ER Downpipes and JB4 on Map 2.

The power delivery is excellent the car runs like a beast!

Downpipes definitely help the spool its basically instant. You hit the gas in sport + and you get immediate power.

I really like the sound of the downpipes with the stock exhaust and the flap mod (flaps open all the time). It gives it a deeper growl that the stock exhaust really needs!

If you don't have a tune and downpipes your missing out!!

Got any videos?

[ES_TRADER]

Would downpipes still help with the spool without a tune?

[AutoTalent]

Video please!

As for OP I've been saying it from day one, if people don't want a full exhaust system just get downpipes and open the valves. It is good enough.

Downpipes with stock exhaust an open valves is plenty loud and sounds great imo. I think its wasteful for a full exhaust I don't believe its worth the cost for the power.

add BMC or K&N filter for even more sound effect

This is my dream combo but I'm too nervous about the warranty. (I'm a p***y I know) I keep trying to convince myself the downpipe will do no harm.

did you have to get the control module with the dp?
i might go this route minus the jb

this setup is something I recommend to all M3/M4 owners, it gives the car a bit more character and power without taking too much from its original feel.

I have the ER downpipes with stock exhaust and I love the sound too. Not sure I f I want to just do tips or get anew exhaust.

[ES_TRADER]

I've heard this setup in person and rode in the car as well. I believe it's just as loud, if not slightly louder than a car with stock dp and aftermarket system. It sounds good but if paired with a good aftermarket I think he sound would be louder and more refined.

Any drone?

Whats with you have to get Downpipes with FLEX?? Can someone who really knows chime in does it hurt to have the ER in the long run or should people run Akra or Eisemann DP's??

[mul1gan]

so whats the consenus on DP, who makes a nice one and does it require any cutting of the factory exhaust or is it a simple swap?

When I installed the downpipes, the stock exhausted bolted up with ease. I know that a flex pipe may take stress of the exhaust under load. But flex pipe can also leak over a long period as well.

I think the fit-ment of the ER downpipes was perfect I had no issues with the install. If you have downpipes where the fitment is not perfect then that's when a flex pipe is more important.

The only other thing I am going to do is get the magnaflow tips I'm not buying a whole exhaust I think it's not worth it.

As far as drone I mean there is a little bit around 60 when your under a slight load but I don't think it's annoying or to loud. If you had downpipes with the flaps connected and then open them in sport + only if u wanted the extra sound would be a good way for those looking for power but not wanting the sound all the time. But everyone's definition of loud is different. I think the road noise from the pilot sports is more annoying.

I'll take some Go Pro Hero 4 Black (One of my favorite sponsors!!) videos today.

Don't forget the charcoal filter delete. You can hear a bit of the intake sound which is great. Best part of this is the mod is free. Gotta love that.

The setup you have is very popular for a reason. It just adds so much in terms of power / sound for a very reasonable cost.

Add some sound clips pls
