What kind of tune?

Reset adaptations perhaps

Check to see if they're touching each other or any other part of the underbody.

This. If you have any issues, always a good idea to call the manufacturer. They are usually able to offer the best support.

Its a common install error when the shop/person doesn't rotate them properly to ensure clearance.

Yes it is actually, resetting your adaptations with procede can help with a shaky idle. If you can,t hear the pipes hitting something I doubt that's the problem.

They aren't clocked correctly or they installed the o2's in the wrong order which will cause the idle and driveability to goto shit.

Stop driving over the rumble strips or take your iPhone off vibrate.

That was what I was referring to, the OP never mentioned he heard metal on metal noise otherwise I would say there is clearly an install problem. He just said vibrating which would mean possibly a rough idle which could be related to other hardware like HPFP or injectors too.

Went through 2 sets of ar dps and never had any rattling, vibrating issue

badass335 · 06-24-2011, 01:55 AM

i actually had this when i had my MS catless ones installed. After a week, went back and had car lifted to see what was rubbing. Turns out, there was a very slight rub. You could see the metal scrap. The installers loosened and adjusted and all has been well since. Mine was funny. If i turned the wheel to the right slight and tapped the brakes to move the car say an inch, the vibrating would go hence why i figured there was a rub. The engine would move slight and exhaust wouldnt rub anymore. Take it back to installers.

djdownfawl · 06-28-2011, 02:32 PM

When I turn off the car after coming to a stop, something hits something underbody.

Also at first start up there is a noise like whissss and it goes away after a 2 mins.

Hate. it..

ar design · 06-28-2011, 03:22 PM

Sounds like an alignment issue - who installed them?

djdownfawl · 06-29-2011, 09:16 AM

Just a local mechanic....

djdownfawl · 06-30-2011, 12:20 PM

Where should i get it fixed from?

ar design · 06-30-2011, 12:27 PM

AK Motorwork, Camber-Toe, both great shops.
