demon bolts

2013zboii

i bought some test pipes.. i want to install them myself. i have heard and read all about demon bolts..

is it worth it for me to add a test pipe?
once i replace my cats with test pipe, will i have to install the demon bolts again or once they are off , they are officially off?


I also bought a stillen lightweight pulley.. worth it? should i let a shop install these??

Its finally time for me to mod my lady.. all the help is appreciated.

If you do it yourself just make sure you have all the tools you need. Unless you know the guy there's no guarantee that he'll do it right or good.

It all depends on how much a few extra horsepower is worth to you. Probably not. Especially if you live in an area with emissions checks.

Unless this is a track-only car and you understand what a harmonic balancer does, no.

Unless you have worked on cars (or other mechanical equipment) before and have all the proper tools, probably yes. Neither is a job for the inexperienced mechanic.

Find a good mechanic you can trust and someone who will accept responsibility should things get bad. I had long tube headers and a cat back installed and thought it was done correctly. Went back to the same shop to revert to stock and they basically butchered my O2 sensors which caused my spark plugs to foul up. $900 fix later, with no assistance frm them, I learned my lesson.
