nfbr Posted December 30, 2009 Report Share Posted December 30, 2009 Wouldn't bother with these cheep crap parts on eBay.Speak to the person building the exhaust and see what size they recommend you should buy. 50mm in/out seems a bit small if using a sports manifold.I would almost definitely add a flexy Pipe in there!

Brammo Posted December 30, 2009 Author Report Share Posted December 30, 2009 I suppose the in diameter should be bigger than the out diameter. The custom exhaust on at the moment is the standard bore didn't want it bigger or smaller because i didn't want to play around with the back pressures I suppose that will be a good reason for having a custom made sports cat I cant had the manifold side the same diameter as the pipe from the raceland manifold and the exhaust side the same diameter as the exhaust.

crash Posted January 8, 2010 Report Share Posted January 8, 2010 I have a 200cell sports cat on my gti, running into a standard scorpion cat back system. Also had it remapped at Awesome and it now pulls like a train, very smooth and a little more torque too.Heard bad things about decatting so I personally wouldn't bother trying it.I can recommend Awesome if you require a remap...which you will as once the sports cat is fitted it feels a bit slow and almost turbo laggy (if indeed this is a word)!

Defcon5 Posted January 8, 2010 Report Share Posted January 8, 2010 Got any graphs crash? Quote Link to comment Share on other sites More sharing options...
AwesomeAl Posted January 8, 2010 Report Share Posted January 8, 2010 This is Crash's Graph...It's worth noting that the BHP figures on the graph are At the wheels and not at the flywheel. Quote Link to comment Share on other sites More sharing options...

pro3mark Posted January 8, 2010 Report Share Posted January 8, 2010 And i'm presuming the graph shows pre and post map? Quote Link to comment Share on other sites More sharing options...
AwesomeAl Posted January 9, 2010 Report Share Posted January 9, 2010 And i'm presuming the graph shows pre and post map?Yes, However you have to remember Pre-Map this car already had High flow Cat, Cat-back and an Induction Kit so would have been a little bit up on standard!As an idea this is a Virtually standard GTI's Graph Quote Link to comment Share on other sites More sharing options...
crash Posted January 12, 2010 Report Share Posted January 12, 2010 This is Crash's Graph...It's worth noting that the BHP figures on the graph are At the wheels and not at the flywheel.Cheers for wanging that up here for me Al.I think she might have a tad more power since this dyno was done now that the clutch is new and bedded in. Pulls like a train...suppose the cold air helps too but deffo worth doing IMO. Quote Link to comment Share on other sites More sharing options...
AwesomeAl Posted January 12, 2010 Report Share Posted January 12, 2010 I think Craig (One litre wonder) was on about possibly aranging another club lupo rolling road day so maybe pop along with the car if it goes ahead and see how she's running Quote Link to comment Share on other sites More sharing options...

Toon Posted January 24, 2010 Report Share Posted January 24, 2010 Im adding this here, saves cluttering the forums up.I had mani + exhaust + sport cat fitted about 2 months ago. The other day the check light came on, so I hooked Vag-com up today and its readyError code: 16517 - Oxygen (Lambda) Sensor B1 S1: Response too slow.Ive read on here that, this is the fault the manifold brings up, just wanting to double check thisAnd also whether this will cause the car to run dodgy, if i dont get it sorted?

nfbr Posted January 24, 2010 Report Share Posted January 24, 2010 Response too slow? That's a bit of an odd one... It's normally "Catalyst efficiency below threshold" ? Quote Link to comment Share on other sites More sharing options...
