Brprs Posted February 12, 2013 Share Posted February 12, 2013 Hello, Im looking for some info regarding the fitment issues some have noticed with their invidia catless divorced downpipe. From what I've read the division plate somehow gets in the way and needs to be trimmed. Some have also noticed " wastegate slap" or "chatter". I have the downpipe in my possession and would like someone to explain this in greater detail. i.e what you did to fix this and maybe some pictures to lighten the stage deux load. So, who wants an e-cookie? Link to comment Share on other sites More sharing options...

Moderators BarManBean Posted February 12, 2013 Moderators Share Posted February 12, 2013 SCASEYS, you don't offer nearly enough useful advice to just run around telling everyone to search. The search here sucks, at least tell them how to search using google. Go away.

Check out the link below to see my VF52 wastegate in operation. The WG doesn't break the plane of the turbo outlet housing. It's when there's a divider plate that breaks that plane from the downpipe side that there are problems. Mine is a MadDad Metal v2 that, at one time, had the divider plate. I have no troubles with a flat face on the DP. Tits mcgee Link to comment Share on other sites More sharing options...
Brprs Posted February 12, 2013 Author Share Posted February 12, 2013 Thanks fellas, this should help. Isearched all over for the past few days and no dice. I agree the search function IS a joke . Link to comment Share on other sites More sharing options...
joeleodee Posted February 13, 2013 Share Posted February 13, 2013 It also depends on which Invidia DP you have. There have been varying runs of the downpipe with different size/shape protruding divider plates. When I bought mine, I did no grinding and had no issues running it as is. As it sits now, it's grinded all the way flush with the bellmouth flange because of the aftermarket turbo I'm running. Link to comment Share on other sites More sharing options...
I Donated Too laff79 Posted February 13, 2013 I Donated Too Share Posted February 13, 2013 I ground my divider down just in case because I had heard of that being a problem. No problems with my Invidia catless. Link to comment Share on other sites More sharing options...
Brprs Posted February 13, 2013 Author Share Posted February 13, 2013 Mine is an auto catless divorced. Id rather not have to grind it down, but oh well we have weld in a wideband and shit anyways. Haha Link to comment Share on other sites More sharing options...

Brprs Posted February 14, 2013 Author Share Posted February 14, 2013 Thanks! I searched so much yet found nothing. Real question is, should i grind it before i put it on or install it, see if it hits and so on? OR is there a good chance my DP is the latest version? I ordered it this past November. These threads are 3+ years ago..lol Link to comment Share on other sites More sharing options...

Real question is, should i grind it before i put it on or install it, see if it hits and so on? See what you can find on NASIOC.com. If you're running a VF40, chances are you're OK. The 2008 WRX didn't have the VF52 (they had a TD04, I guess)... so, my opinion is, the DP's designed for 08+ WRX/05-09 LGT did not take into account whatever differences in geometry exist that cause the VF52 wastegate to hit the divider plates. This wasn't a problem until the 2009 WRX came out with a VF52. That's when people started having issues... and of course anyone that retrofits a VF52 runs into the same problem.

Brprs Posted March 13, 2013 Author Share Posted March 13, 2013 Sorry to bump this again, i just want to be double sure so we dont have many setbacks come install day. Here's some pictures.. does anyone think this needs ground down? http://i1241.photobucket.com/albums/gg502/00rs25/2013-03-12_20-45-18_14_zps567c8d23.jpg http://i1241.photobucket.com/albums/gg502/00rs25/2013-03-12_20-45-40_132_zpsb9d4f4fa.jpg http://i1241.photobucket.com/albums/gg502/00rs25/2013-03-12_20-45-29_423_zpse5a91454.jpg Link to comment Share on other sites More sharing options...

DeltaNu1142 Posted March 13, 2013 Share Posted March 13, 2013 Should be OK, from what I've read. It's when you upgrade that you'll have problems. Tits mcgee Link to comment Share on other sites More sharing options...
Brprs Posted March 13, 2013 Author Share Posted March 13, 2013 Oh ok. I read some of the reviews on here and some said they had issues with theirs and they too had the vf40. Link to comment Share on other sites More sharing options...
iNVAR Posted March 13, 2013 Share Posted March 13, 2013 GRIND IT JUST TO BE SAFE. Or you'll be kicking yourself after you install it, go out and do a WOT test, overboost, hit fuel hit, throw a CEL and fly through your windshield. Then after you recover, you'll have to pull the DP anyway. The extra little bit you grind off isn't going to affect performance whatsoever. http://legacygt.com/forums/showpost.php?p=2622039&postcount=25 Link to comment Share on other sites More sharing options...
DeltaNu1142 Posted March 13, 2013 Share Posted March 13, 2013 True... I'd be pissed to install only to have to pull it off to grind the divider anyway. Tits mcgee Link to comment Share on other sites More sharing options...
Brprs Posted March 13, 2013 Author Share Posted March 13, 2013 How deep of a notch? Edit: nevermind i see it. Double edit: i cant really tell where you grinded the score area. Care to enlighten meh? Link to comment Share on other sites More sharing options...
iNVAR Posted March 13, 2013 Share Posted March 13, 2013 My picture doesn't show the grind. This does: http://legacygt.com/forums/showthread.php/question-invidia-dp-85295p2.html?t=85295&page=2 Link to comment Share on other sites More sharing options...
Brprs Posted March 13, 2013 Author Share Posted March 13, 2013 Jesus, how did i miss that. OK. Will it hurt to have a notch that's more even..maybe 16th an inch deep like you said and maybe 1 1/2 long? Instead of a little notch. Link to comment Share on other sites More sharing options...
iNVAR Posted March 13, 2013 Share Posted March 13, 2013 You could do the whole edge if you want, but it's a waste of a) time b) grinding material. Grind what you see in the picture, and don't skimp too much or you'll end up removing it to grind again IF something were to happen. I'm telling you man, in this case, better safe than sorry.
