1999B4

I have a GFB Respons Bov on my legacy b4, did some research before buying this one apparently others have problems with vta bov\'s because of the maf causing the car to run rich, revs fluctuating etc.. with the GFB t9000 its simple just take the factory diverter out and replace by unbolting couple bolts, vac and recirculating hose. It is adjustable so can be set to be fully atmospheric, recirculating or 50 50 with fully atmospheric it is louder but I had problems with the my car running rich and causing a lumpy idle so set to 50 50 sounds decent is not as loud but have no problems with it also noticed better throttle response.

Have tried playing around with the wire connecting to it in the boot don\'t think that I can disconnect from there, how can I disconnect from the exhaust will add photos. Dont really want to cut the wire as I might have to change the exhaust back to the factory depending whether or not I prefer the new one. The aftermarket one is a diff back Kaikamoto big bore with 5" tip anyone know if they are good quality? Boot Actuator Exhaust thanks in advance.

My brother had a greddy bov in his Evo it has a nice fluttering sound. I don\'t think sequential bovs suit subarus I have a gfb t9000 in my b4 sounds decent it is quite loud when fully atmospheric I had problems with the car running rich and causing a lumpy idle because the maf so set it to 50/50 still sounds the same and reasonably loud. Have been told by others by having a hks the car won\'t run rich and the revs won\'t fluctuate etc...

Hi all, Recently bought a aftermarket bolt on exhaust to replace the factory back box on my legacy b4 was wondering how to replace the exhaust it is an electronic one, I noticed that the actuator is connected to the exhaust which opens the by pass valve when the secondary turbo kicks in how can i remove the cable connecting to the exhaust? Also what are the pros/cons associated with replacing the exhaust any problems with the of the electrics, turbo spool back pressure etc have been reading on forum sites saying that aftermarket one will increase the flow and decreased back pressure will this have an impact on the primary turbo i.e. spool, premature wear etc.. Just after the Subbie rumble LOL. Any info will be appreciated.
