Finally got installed by my buddy with a lift. I can't believe some have installed at home. Amazing sound with the PSE I had installed. I was intending to record solund before and after but my iPhone screwed up!

 

good choice!

The lift makes it much easier! On my old car i had installed in my garage and the limited space increases the difficulty factor quite a bit.

Now i will put the bypass again on my newly acquired 09 4S but i will go to a friend's shop to do it...

 

Did mine on my back in my garage. It wasn't awful, but a lift would make the job soooo easy. I love my Sharkwerks.

 

Anyone notice more vibration compared to the original?

 

No significant vibration observed on mine..I only notice the passenger seat vibrating more at idle slightly

 

Didn't notice any vibration. Installed it on my back in my driveway.

 

installed on my back in the garage. Considering it's the first DIY i've done, it was pretty simple. Only PITA was reaching the top bolt on the cat flange, but managed that with flex gearwrench & swivel socket adapter.

No additional vibration noticed here.
