I am running a 03 Lancer LS.
I just modified with RRM header, test pipe, magneflow
exhaust, and RRM short air intake.
I just found out that my car shoots out some flames from
the exhaust while I hardly hit the gas.
Why will cause that phenomenon??
Can somebody explain to me please??

 

That means that you are running WIDE OPEN! you arent restricted at all... thus you get some occasional flames

 

That's cuase you don't have any cats in the exhaust. Straight pipe all the way allows burning fuel to escape, thus flames out the exhaust.

 

so will this phenomenon hurt the car??

 

and how to prevent it,thx??

 

No

 

might melt bumper a bit

 

well although it may look dangerous, you should try to fix it, you could get a nice fix it ticket for that, like IamKar, endangering other drivers. lol

 

I'm sure you can find some sort of flame arrester/supressor that will fit in the tip of your exhaust.

 

Wow, it's amazing how much more wide open your car runs, seeing as how I had a header, downpipe, testpipe, and axleback exhaust with no flames. I guess the resonator really makes that much of a difference, although I doubt it.

till I see pics.

 

Rabbit did you end up fixing the problem?? and how did you fix it?

 

the flames are fun come on now if u want som serious flames if u have a strait pipe the hole way (ie no cats or rsenotaor and a header to rid the first cat) just add a spak plug to your tale pipe and hook it up to a swich and a postie power source and whalla 50 style 5 foot flames shooting from your tale pipe we hee now thats the olde school ****

 

yeah Iamkar had those flames and started firing on people that rode to close to him on the freeway. umhum, he got a fix it ticket too. lol

 

straight pipe alone won't cause it...you need to be running fairly rich too.

 

rofl. phenomenon... I like that.
