Down pipe no tune ?

K8_M235i · 05-09-2020, 03:44 PM

I currently have a fabspeed sport cat dp and a dinan intake. My car will randomly throw a cat efficiency code while cruising on the highway. It is all stock engine wise other than an ER charge pipe.

It hasn't bothered me enough to want to tune my car.

I've thought about pulling off the intake and seeing if it comes back.

I forgot to ask, but how's the sound? I'm actually NOT looking for a lot of increased volume, albeit a little bit is certainly ok.

I'd say 10% more on cold start and acceleration. In Sport, mid to higher RPM's slightly louder. So I'd say "a little bit" is accurate.

I notice it, wife barely did...bit deeper.

Got a chance to drive more today, def. stronger pull. Baseline is 295, and pulled 321 WHP.

Tune will seriously wake up the car. Feels like night and day. Need a charge pipe though.

Holding on tune, would need Intercooler, and putting $$ to handling.

ER chargepipe was put in also

Get some stickers. Good for 5-10 hp each.

20% louder on cold start then it quiets down and gets louder only on high RPM

Yea I had said 10%, but 20% def. closer. Had some warm mornings, but on a colder morning and parked just outside garage, could notice more. Not crazy loud.

Anything over 3K rpms you notice more also.

Great add and nice pump in torque
