They also managed to installed my Black Chrome 3.5 Cyba Quad tips and aligned that too.

Here are some of the Pictures, not the best shot but all i got







I got more pics of the whole process should anyone wanted to see them just PM me.

The initial start up sounds definitely added a nice growl to it and did not notice any drone on a normal highway driving at all.

The shop suggested if i need more sounds is to delete the resonator and do a straight pipe which will most likely be my next mod.

I also used a stainless steel hose clamps to hold the valve open if anyone curious whether i left it close or open.

Any question, please let me know.

Thank you all!
I know this is really old but do you remember how much they charged you to do this work?
