[~ ~ Cal ~~]

I'm trying my best to get out of moving out of my GLA flat that weekend but will catch you soon anyway as I need to use BHP's efficient services for some new Motul oil and a new bulb ( with fuse tapped in somewhere 0 for my Lamco gauge ( which i use a lot these days

PM if need be as I'm trying to keep this thread informative.....

Thanks Rusky ( and yes the stickies will be welcome in white for me )

<< All the bugeye and Blobeye WRX's have 3 cats - Uppipe, Downpipe, Cat pipe.

The Sti's from the same years have only got 2 - Downpipe and Cat pipe.

This is why the WRX's have an EGT sensor in the uppipe, to monitor egt's in case they get too high and cause the Cat to disintegrate and fly into the compressor wheel causing no end of harm to the turbo.

ps - just noticed I pushed the 4 instead of the 5 should have read VF35. >>

Cheers for that Russell! The exhaust guys thought there were only two - downpipe and the stand alone cat. Looks like I'll need to remoce the up-pipe cat too. Still don't want the headers. I note Andy F has ported the standard ones so maybe get that done. What is actually done when the headers are ported - is that literally polishing out any imperfections inside???

Wrxmania send Harvey Smith a pm and he will tell you about the porting of headers you read on here and sn he the person to speak to

[andrew_forrest]

Harvey will do you a set on exchange for around £100 Brian. My WRX headers are 'Harvey ported'

He makes an excellent job of them, there is a good few hours work involved even when you have all the proper cutting tools and know what you're doing.

Porting the headers is not easy as there is a lot of metal to remove.

I've done several sets now and always seen an improvement in flow on all the cars I've done it too. Your looking at about 3 hours work to do it properly and thats using proper carbide burrs which cost 15-18 pounds each.

Russell

ps - Please bear in mind that doing it wrong can actually reduce the efficiency of your cars breathing so if your in any doubt, get Harvey to do them!

Thanks for that Andy/Russell.

My main aim is sort the exhaust and remap at that, still able to pass an MOT and improved response from the engine. I am not interested in big power - just more flexibility.

More power equals more flexibility
