Average Gain Overall?

[dash.90]

So I'm sure this topic has been brought up been haven't been able to find something exactly. With the 4x tune, cat back exhaust, downpipes, CAI, whats the average overall hp/torque gain considering the car is stock at 365

Well cat back is rumored at almost 20 hp downpipes are another 20 to 40 I think. Cai might be worse then stock depending what you got and I'm not sure at tune bit it should be like 450 to 500 at the crank would it not?

Seen some pretty nice numbers without downpipes

Catback is shown to be pretty pointless except for a cool sound. Maybe 4-5 hp mainly from the 3rd cat delete. Downpipes are the real power adder which is going to be around 15-20 hp. Catted are a few hp less than catless (only like 2-3hp less).

I don't have a Livernoise tune (I have unleashed) so hopefully someone from there can chime in more accurate numbers, but I'd guess around 130-140 crank hp gain from that setup (4x has the 160 tstat + 3 bar which I'm counting for those numbers). I believe Livernoise says that setup is good for like 400-410 awhp, but don't quote me on that.

I think if you do a search, EBPF founder 4DRHTRD created a fairly inclusive thread, that compiled all the various gains of each mod, by each vendor.

Maybe SHOdded can find it & link it here??

Good idea Mike!  Here's the list 4DR posted... It's pretty close to the mark on WHP added per mod for almost anything you might do and has costs included. This might help get you clear answers.

I'm guessing you have about 375-380 HP at the wheels. About 80-90 above stock.

Just to touch on the cat back set up- LMS told me they got 12hp on the dyno from the Corsa kit.

good to know. Not to mention it sounds great.

I have Corsa exhaust and before I tuned it a guy with a stocked SHO from work said it felt a lot faster with just the exhaust he's also a service tech so I'm sure there is some performance behind the Corsa exhaust.

Forgot to mention that he owns one.
