you guys do need to know
when you have a habit of spray here n there trust me you gonna empty your bottle fast
no matter i dont use a lot statement
but every 3 bottle you need to check for your spark plug condition because they go bad real fast
so basically at 3 or at 4 bottle you need to swap your spark plugs
i know denso is a good plugs but
i personally like the NGK laser Ir plugs and our car takes 8 -_- and plus the labor unless u know how to swap um
but hey if u dont like the 400 whp which is pretty fine but for a realy fast few second of feeling from 500whp
go for it...
just dont install nos too hardcore like direct to the engine just a intake pipe is fine
jsut my 2cents

spark plugs is not fun to change on these cars. its not hard but its somewhat time consuming if you dont want to scratch things up and properly torque all plugs to spec. thanks for pointing this out

Great feedback guys. Much appreciated.
Honestly the headers scare me somewhat based on the constant post containing cel issues.
All in all it seems the headers are the best bang

Agreed. I guess it depends how sensitive a person is to drone, but after installing the PPE headers, what little drone my Borla system had, went away. Headers tend to give the car a deeper sound, more than anything...a little bass in the voice.

Headers was the greatest thing I did for the car, performance wise....did not have CEL issues (I'm running PPE with Magnaflow high flow cats). Sounds incredible with the Borla catback.

NOS is probably a bit too hardcore for me, the car is quick enough, I'm now focusing on tightening on tightening the nut behind the wheel :-)

Really like Abohler set up, ready to go at anytime at the flip of a switch.
I really think it depends like some of the other users stated on type of driving. I was going for biggest power boost for best price. Gained 110 HP at the wheels, and about 150TQ at the wheels. The one plus is since everything is electronically controlled there is almost no room for error. You just won't see those types of numbers spending the same amount of money on a header swap.
