MOTORDYNE ART Pipes - Review

Osiris · 09-30-2011, 11:01 AM

I read somewhere earlier in this post that a bolt under the driver's side needs to be cut short to avoid rattling against these pipes. Is this still the case with the latest generation?

Yes, that stud poking out from underneath the driverside floor board needs to be trimmed flush.

Last time i had my car up on the lift, i noticed a stud on both driver AND passenger side. Are those different than the one we're referring to? Does anyone have a pic of it?

The stud on the passenger side is there but it isn't a problem and you dont need to do anything with it.

You're correct. There is a bolt poking thru on each side. However, only the drivers side needs to be cut down. Takes all of 30sec with a saw.

Tony, i'm not quite to the 1500 mile mark and the metal sound is gone, so that might have just been something that was loose in the pipes, or maybe it just cleared up on it's own.

I still have that sort of I guess sand sound? It's only when I let off of the gas, as soon as I put the gas down even a little, it goes away. Is this a normal thing or does it sound like a leak? Is there an easy way I can check to see if it is in fact a leak?

If anyone else has this sound let me know. If it's a normal thing then I don't care.. it's not irritating to me, but I don't want it leaking if it shouldn't be obviously.

Its probably the normal break in process of the fiberglass. Its probably just about done.

yeah, it definitely sounds like just sand or something in the pipes more than a leak... I just wanted to check. I just wasn't sure why it only did it under deceleration.

Sounds like you're referring to the "hiss" that happens on deceleration. It's normal... kinda does sound like sand sifting through something.

NOTE: There is no more fiberglass being used in production ART pipes from this point forward.

So, I beleive the future-coming AWD version of ART pipes will not use fiberglass either?

There is no more fiberglass in any of them from now on.

AWD clearance will be confirmed next week.

Perfect news!

Will there be two versions of ART pipes: for RWD and AWD? Or only one universal?

Motordyne · 09-30-2011, 04:53 PM

It may simply be a soft rasp if it only does it on decel.

The hiss that occurs on decel around 2K rpm is normal.
