Just picked up X51 headers from Brumos Porsche. Unfortunatley they are covered in stickers from the factory. Do these need to be removed before I install them? Don't want to start a fire.

 

I would remove the stickers. Be careful not to break any manifold bolts during your install.

 

Thanks, they r a bit tough to get off. I will try some adhesive remover.

 

Get them off the best you can, after one or two WOT passes they will be toasted off.

I will be installing this week, how difficult is install?

 

Not sure. Will try it in my friends garage with a lift and see if I can do it myself. O/w off to a shop.

 

if car is old - pre-soak bolts very well and be careful applying brutal force when removing them.
it s also reccommended to replace header bolts once they were unscrewed, but, i am not so sure if it is very important unless you had to struggle a lot.

honestly if car is not brand new and old headers are toasted to the block i would drive car to mechanic to get this done - job by itself is very easy and if you will have no issues unscrewing those bolts you wil be done in 3-4 hours top BUT it you will break off bolt`s head and leave body in the engine block - it is a very very major PITA.

difference between you an mechanic is that mechanic knows by heart how much force he can apply there before bolt`s steel will break.
in my case - when i was replacing my cats i broke off 4 bolts out of 6. they simply did not go at all even after 3 days o pre-soaking and applying a bit more force made them simply snap in half. but it was cats and i do not care - if you leave bolt`s body in the block you will have to drill into engine block, long story short you do not want that.

i think last person who did this upgrade on an '06 car was cattman ad his header bolts did go very easily. if i`m not mistaken tightening force on headers is 17lb.ft, so if you dial in 25 or so lb/ft on torque wrench and it is not enough to undo those bolts - that would mean you go to be careful.

Nuts on cats bolts - connection between cats and headers - are also 17lb/ft as it seems. be careful there too if you do not have spare cats. as i spoke before i broke off mine - nuts were toasted to bolts permanetly.

 

Use a heat gun to help remove those stickers.

 

Will a hairdryer work?

 

As Utkinpol says..soak the bolts down with liquid wrench over night. Even then it may still be a struggle. My car was only 6 mos. old when I did it so I had none of these issues. I removed the OEM exhaust, reinstalled the new exhaust (headers, cats and Borlas) all in 3.5 hrs. with the car on phone books to lift it up a tad so I could get under there. I lent out my ramps to a buddy who was installing a set of long tube headers on his 08 Shelby GT500 and didn't want to wait.

Don't even sweat the stickers..

They dont get hot enough and your wife might get mad.

If you got most of it off, it will just burn away.

 

I agree the sticker will burn off. However, if you do want to remove "goof off" or lacquer thiner will remove them.

 

Hairdryer worked like a charm. Sticker and goo free. Took about 5 min to get all six stickers off.

 

Funny, I too could not wait to get my Borlas put on by the shop so my friend and I jacked the car up onto some 4x4s and put in on in a few hours. Will prob try the same with the headers and cats if I can get the O2 sensors installed correctly.
