Correct me if I'm wrong please but it looks like you are saying you lost ~16 whp and tq from just switching to the xyz cat version? The other dyno line was with the xyz straight pipe tuned for that?

 

anyone running the ART pipes on a stock exhaust with a MD MREV2 and spacer?

 

bump,

Is this true? I currently have berks hfc and wanted to switch to md art pipes with XYZ resonated.

 

No. I only mentioned switching out the Straight Pipe for the HFC Accessory for sound purposes between the videos. The dyno was Pre-Tune VS: Post Tune.

 

ahh, didn't have the full context.


Your set up sounds amazing..

 

I'm thinking about pulling the trigger on these but I have a question for those that have these installed. I see a couple ppl have had their CEL come on, but only one said it was due to the MAF.

Can anyone else that had their CEL come on after install chime in and let me know if it was due to the ART Pipes?

Just want to double check before I purchase, because from what I understand, these should not trigger the CEL.

Thanks

 

I've never seen them trigger the CEL.

For whats its worth, the ART pipes on a sedan eliminated drone on the Motordyne setup

 

+1 No CEL for me either and the ARTs made my VQ exhaust even more quiet no drone.

 

no cel for me. and it made my exhaust quieter from hfc

 

NO CELL LIGHT, NO DRONE ON MINES EITHER THE ONLY THIS IS IVE HAD THIS EXHAUST FOR A WEEK AND IT SMOKES A BIT EVERY NOW AND THEN, tONY TOLD ME IT TAKES ROUND 1K MILES FOR THE SMOKE TO DISAPPEAR .sO FAR IT MADE MY g RUN BETTER A LOT LOUDER AND SMOOTHER BUT WITH THE STILLEN EXHUAST I NOTICE SOONEST I PUNCH IT IT RASPS =( SO I AM DUMPING MY STILLEN AND BUYING MOTORDYNE V2 TRUE DUAL WITH X PIPE FROM TONY SINCE HE TOLD ME THERE IS NO RAPS FROM THE ART PIPES AND THE MOTORDYNE EXHAUST.

 

are the people with CEL's from the ART pipes just HR people? or also DE?

 

how'd you not notice your cap locks was on?

 

Haha funny you should mention IT my Key board is ACTUALLY MALFUNCTIONING every now and then =( i am buying a new one soon thnx for noticing LOL.
