Hey there,

Has anyone installed KN air filters. I was told that the exhaust sounds alot more sportslike.
The salesman at Advance Auto installed them on a friends Crossfire.

 

Exhaust? I did notice a little more "sound" from under the hood with them..

 

I have K&N air filters.
the noise gives a marginally increase in Induction roar, but only when you open the throttle hard.
No exhaust noise increase.

I removed my rear silencer unit, opened it up & chopped out all the tubes and baffles inside, re-welded it together, and WOW, nice little rasp from it now....
The note, is still SILENT at a constant speed, but if you cog down a gear and open the tap, she roars nicely, but not enough to upset all your neighbours....

Just give a nice rasp note and you hear your Xfire grizzle nicely..
The performance it changed marginally, I had a tinsey bit less torque at lower revvs, but power ALL the way to 6,000 revvs. The power comes in, in abundance at about 2,200 revvs and stays there all the way.

Sounds nice too, and is a very cheap hop-up, and won't cost hundreds of $$$$ for a new back box.

there is an article on this site with pictures, but if you want to mail me your private mail address, I will gladly mail you sketches of exactly what you need to do to the silencer.

keyword being "salesman" 98% of the time when I got to a dealership or parts store they don't know anything about a crossfire. K&N filters have been known to give a small increase but I'm sure this guy is exaggerating.

 

I ordered mine a few days ago from partsgeek.com Best price I could find.

 

I had my K&N filter installed about 5 months.
It absolutely does not affect the exhaust sound.
It suppose to increase the about 5-10hp of engine horsepower.

I had a sponge air intake on my last car, it do sounds different when you accelerate.
If you only replace the air filter in the air box, it won't make so much different

 

This ^^^^^^ with a tiny kick in the seat of the pants.

 

I have been running K&N for more then 4 yrs now , easy to clean and take care of ,but your not going to get any more HP out them ,get a tune with them and Ex , and you will have few more HP , and great sound ,

 

haha awhile back i installed my Needwings DCAI and I needed some power steering fluid to top off my res and i went to three dealerships around here all Chrysler ones, and I told them what car and what kind of fluid I wanted and they look at me like I had three heads and said what's a Crossfire...

 

^^^^^LOL
