Default After OBX header installed..

recently i had bought: Brenspeed tune and BBK cold air intake as well as a set of OBX headers.. The Tune and CAI was amazing.. I'm running the 93 oct tune.. I could tell alot of diff between the stock and the new tune.. I finally got the headers, so off to th, to the installer it went.. Headers, Stage 8 header bolts, O2 Ext., and motor mounts went to the installer, with the car of course.. Installer said like everyone else has, driver side install was a p.i.t.a.. BTW, i went with the LT H with Rezs.. When i got the car i really couldn't play with it cause of all the danged rain we have had.. After i got it out when we had a half day dry spell, oh man.. They sound great.. I could tell the more power was there.. It was amazing.. i'v had alot of compliments over it.. Very well worth the upgrade imo..

I have only got 1 or 2 problems after the install.. Luckly, i have ZERO play in the steering.. However i have a slight pop in the steering as the dead center of the steering pattern.. no biggie to me.. The other is however a never racking sound at times.. Not out side, but it sounds like it coming from the dash.. Its not a squeek, it not a rubbing, i don't know how to describe it.. It happens at diff ranged of rpms.. There are no leaks but could it be a clamp stretching out after the header is warmed up and rattling?? I have no clue on this one.. Any suggestions to check would be great..

Since the install my exhaust are very uneven in the rear of the car.. How do i fix this hanger issue??

Its not a hanger issue, just crawl under your car and loosen the 4 bolts behind the h-pipe and wiggle the clamps around so they are nice and loose. Then go to the back of the car and hold your tips where you want them and have a friend tighten down the nuts on the clamps. I am assuming you dont have an axle-back exhaust yet, but if you do, you might want to loosen those bolts too.

As far as the rattling, it might be your headers rubbing the steering shaft. I would crawl under your car and check the clearance between headers and steering shaft while you are adjusting your exhaust.

Regarding the rattle, also check the mid pipe hangers. That's another common source of rattle.
