Usually when you install a cai you will take outyour whole filter box and everything, so yea.

K&N says you gain 10 hp on a stock motor. I say this is bull****. I doubt you get 5 hp. I installed one and didn't feel a difference, It felt like i lost power actually.

Well I can gaurantee you did not LOSE HP... and 9hp is not a difference you will really feel! It is a difference that will take a few tenths of a second off your quarter mile time at best!

For the OG poster... removing the silencer is in effect a cheap CAI... it will not harm your motor any, and will not add a huge difference in performance.... but then nothing aside from a blower or turbo will add a huge difference in performance in these cars... everything other than a power adder is just a little something to give you a bit more of an edge over stock!

silencer removed with a k &n filter is dyno proven 9hp...there is a sticky on it, in tech articles and how to's.
Ummm... more like 3. I know, I dyno'd it. 226rwhp stock, 229 with silencer removed and K&N FIPK installed.

I removed mine and have a K&N drop in filter installed. Stock airbox is still on the car.
I noticed with the silencer removed I have a little more top end pull, however I seem to have a very slight mid-range sag when the weather is hot outside and I've driven the car on a long trip.

I put back the silencer to test and sure enough the sag is gone.

Not sure what to make of it.

here ya go....read the article....if you add a k&n its about 9hp just as i said.

remove the silencer (4 -5 hp).....add a k& n (3-5 hp)....equals about 9hp = pretty much a cai

HAHAHAHAHAHA please, please, share your crack

a CAI will net you 1 hp, someone on yellow mustang registry dynoed a MAC CAI and MAC cat back and got a total of 4 horses

removing the silencer wont do anything more then a CAI, which is nothing, however, it can cause some terbulance in the MAF and cause gas milage to go down, happend to me

+1. 3 hp is more like it. You couldnt get 9 hp unless you did like heads+cam+full exhaust and then upgrade the air filter!
rofl you guys are nuts!! heads...cams...full exhaust, then upgrade the filter.....for 9hp?!?!? dude....put the pipe down.
I think he means you'll gain 9 hp from the air silencer + K&N after doing those mods. It's like putting headers on NA and getting 10hp, and putting headers on F/I and getting 25.
