Hi guys, I have just fitted a standard recirc valve to my Impreza as it was fitted with a Bailey dump valve before but this seems to have cut out all of the exhaust pops, I'm guessing this means the car is not running so rich?

 

It means the cars running as it should. And not putting un-burnt fuel into the exhaust which ignites and causes the Pop.

 

bet you would prefer the pops back though ! Even though the car is running right now ?

 

Thanks guys, lol yea they are a giggle!

 

You can get them mapped in. Duncan Dynamix did my last one and was like having full Anti Lag.

 

You dont always have to have them mapped in, it can sometimes depend on your exhaust as well. mine pops with no effort at all in 4th,3rd,& 2nd just buy lifting off with an afterburner vortex.

 

yeah they were a little loud lol

 

Would tje old Bailey one have done it no good in the long run?

 

No, of course not.

Apart from given you bore wash, leading to excess upper cylinder wear, possible valve burning, damage to any cats, dilution of your oil.....no damage at all, and well worth having, just for the noise as Charly said

 

U guys are lucky. The pe*** who done mine reckons he cld not do it unless I changed up pipe. So changed up pipe and still could not do it

 

Mine is fitted with the OEM recirc, and still pops and bangs.

 

He wasn't looking at the right map then. Maybe why he has left the country

 

mine wouldnt pop or bang when duncan mapped mine, well just a little pop that wasnt loud lol but i now took the resonator pipe off which does help it to pop but not loud like bangs when tapping the throttle. but i still have the uppipe still in
