GC 435i shoots flames! PLM EXHAUST

What's up everyone!

Thought I would share my experience with the PLM Exhaust!!

My car is kind of moded..

ER CATLESS DP
VRSF CP
VRSF FMIC
BMS INTAKE
PLM MUFFLER BYPASS
BM3 STAGE 2 93OCT AGG

I'm running the burbles at max aggression.. and believe it or not I'm getting straight flames. They last briefly, but they are there.

I hit up BM3 and asked if it was ok and they said absolutely! Also stated that I shouldn't need to change my spark plugs!

I will post a video soon!

curious because I'm about to put a new axle-back on in a few days, what did you do to the plug for the actuator on the left exhaust flap? remount it to the new exhaust, mount it somewhere just kinda there so it thinks it's functional, or just left it unplugged? I guess I'm worried about it throwing a CEL..

I unplugged it and left it there. No cel. You don't need to do anything with the plug, you should be fine.

My friend's 435i shoots small flames with the stock exhaust and a catless dp on max aggression for bm3, this thing must be crazy.

Glad you like it OP

Straight pipe w/ catless downpipe + max burble must be super aggressive. Too aggressive for my taste

It's a simple muffler delete. Couldn't see how much could be wrong with it.
