ok this is probably the 3rd thread ive asked this queston in.. noone is replying.. but got the rrm header.. it runs fine.. still got stock exhaust.. when i rev it past 4k.. as its going down i can hear somewhat of a pop.. more like a crackling?.. sounds weird but the car runs fine.. i called RRM nd they said its just backpressure cuz i still have stock exhaust so my header is choking.. any input? what else do you guys think it could be.. anything to help me understand it better

 

. . . this def sounds like a guru question

 

yes please someone help me.. just to get this worrying mind to calm down. i've had the header on my car for almost 4 days now but it runs fine it just gets me really worried when i can't understand something

 

Probably normal, can't say I really notice it on my car.

 

it may be an exhaust leak. when i was working on my wideband install, i stripped the threads on the cat flange where it connects to the downpipe, so i had an exceptional exhaust leak, which yielded LOUD exhaust and popping when you would let off the throttle.

 

come on, are you guys serious? you all don't have the lancer fart?

don't worry about it. a lot of it has to do with the rich fuel maps (the pop)..i get a small backfire EVERY time i hit open loop. as far as i know the crackle just has to do with back pressure.

there have been 3 lancers in my family and i know 2 kids in the area that had/have lancer and they ALL have done that...even stock.

 

thanks for the comments!! defnitley feel alot better now

 

yeah its normal

 

Mine pops quite often as well... so I wouldn't worry about it.

 

never noticed it when i was stock, but every once in a while i'll here it now.

 

it's much more discrete on the stock lancer

 

i was just worried because i've never heard it when i was stock.. now i got headers and stock exhaust and now im hearng it so...

 

I Say you get rid of that stock exhaust

 

my lancer pops too.
Its just normal

 

You're just fine. How do you like the headers?
