Just wonder about test pipe?

weihao3636 · 03-22-2014, 02:08 AM

I was thinking of the Oem exhuast mod or the acm I was wondering will it drone with the set up

Acm or Oem exhaust mod with test pipe? Really looking into the bpm that why I was that set up and need to know does it drone on highway when my windows are up.

When you want test pipe with the lowest level of drone , go for the Oem exhaust mod. the 2 perforated pipe replacement ! (no doubt)>

ACM will be (too) louder, so also the level of drone(to much) in combination with test pipes !

So the Oem exhuast mod + test pipe is good?

For the lowest drone level, yes it is !
As for the Oem exhaust mod. it sounds very nice and sporty but when you add test pipes to the Oem. exhaust mod. sound will change,it will be louder and turn to a more raspy sound !

Here is how it sounds ; Oem exhaust mod.(2 perf. pipe replacement) + test pipes......

Test pipe = rasp, regardless of the exhaust you install

I had cat less xpipe and stock OEM exhaust which I loved. No drone at all and really nice sound. Thought I wanted it louder so did OEM perforated method and than it was awful sounding. Really loud, drone was present and lost its refined sound. Hated it. Its all relative as its quieter than ACM plus test pipes but your best option and truly only setup with zero drone is test pipes and stock rear exhsust

This is my OEM exhaust mode and Test pipes car. Just added test pipes after 5 months of having OEM exhaust mod only and the sound changed drastically, no drone but the volume when you get on it turns heads big time.
