What have been the Average HP gains when installing the Injen CAI to a TC with TRD Exhaust? Where am I going to noticed the added power? and Is my car gonna run ____ty for a lil while after installing?

I would search... all these numbers are avaliable in other threads

aint much
not a noticeable thing, not really
you'll hear it more than anything

My butt dyno felt some definite gains with the intake but felt nothing what so ever after installing the exhaust. Keep in mind that whatever you gained, your not going to notice it anymore in a few days.

According to what I have read (from Injen) it is said to be 12 hp.

Now before you attempt to flame me reread what I said "According to what I read (from Injen) I also didnt say I believe it, but the question was what are the hp gains and I simply stated what I have read...

thanks guys, yea i just want an estimate, so i can estimate where I am hp wise. thanks alot! i appreciate the info

dont guesstimate your HP
get it dyno'd if you want TRUE numbers

ok

GSC did a dyno of the Injen vs others. But that is with an Alphawerks header.

Also I have seen people dyno 147whp with just the CAI, then 150 with the addon of the TRD exhaust. Thats on a 5spd.
