SarahJon Posted September 27, 2012 Share Posted September 27, 2012 Hi, I've got a 1994 stock TT and wanted to replace the stock system from the catback just to get a bit of a nice purr as opposed to stock silence I have bought a second hand Whifbitz 2.5" system. I know that on Whifbitz site it states that this is designed more for the NA but I did some research on here and found a few threads where it was stated that fitment on NA's and TT's was the same from the catback (moral of the story - should have gone from what it said on Whifbitz site!!) and my engine is and will remain stock so thought that the smaller pipe wouldn't be a problem at all from an air flow perspective. We're now trying to fit it and it won't fit over the little bit of pipe that extends from the cat Is it that there are differences between the NA and TT from the cat back that I didn't find out about or is there something a little bit amiss somewhere?? Not sure whether to get a decat pipe and solve the problem that way or whether to sell the Whifbitz exhaust on and wait for something definitely TT compatible to come up. Any help or feedback would be welcomed as I'm a bit confused about why it won't fit at the moment. Thanks all, Sarah Quote Link to comment Share on other sites More sharing options...
Nic Posted September 27, 2012 Share Posted September 27, 2012 Only the first cat is different between the TT and NA, the 2nd cat and cat back exhaust are the same fitment. Can you post up a pic showing the problem? Quote Link to comment Share on other sites More sharing options...
SarahJon Posted September 27, 2012 Author Share Posted September 27, 2012 Will just get my tea eaten and get a pic up asap. Thanks! Quote Link to comment Share on other sites More sharing options...
DuaneT.Turbo Posted September 27, 2012 Share Posted September 27, 2012 Bit strange, my second cat didnt have the bit of tube out the back, but my first cat does... Quote Link to comment Share on other sites More sharing options...
Nic Posted September 27, 2012 Share Posted September 27, 2012 Pic of a standard 2JZ-GTE 1st cat (smaller one nearest the engine) and 2nd cat (longer one that connect to the exhaust), the exhaust mid pipe should bolt onto the flange on the left hand side.

I was just about to upload a pic but you beat me to it. If you look on the left where the mid pipe should bolt on, there is a short pipe sticking out past the flange. The prob we have is that this won't fit inside the mid pipe so when you try to bolt the mid pipe on, there is a gap of about 10mm between the two sections.

Noz Posted September 27, 2012 Share Posted September 27, 2012 Get some photos up mate. You may have to weld on some pipe and use the flange I sent you onto the newly welded pipe to extend it. Sound's like the cat has one of those slip and clamp type joiner's rather than 2 bolt flange which all stock systems usually run. Quote Link to comment Share on other sites More sharing options...
DuaneT.Turbo Posted September 27, 2012 Share Posted September 27, 2012 Or grind the tube off the cat? Quote Link to comment Share on other sites More sharing options...

SarahJon Posted September 27, 2012 Author Share Posted September 27, 2012 Or grind the tube off the cat? That was my next question tbh. Wasn't sure if this would cause any issues though. Quote Link to comment Share on other sites More sharing options...
SarahJon Posted September 27, 2012 Author Share Posted September 27, 2012 Here's the cat and the offending bit of protruding pipe... Quote Link to comment Share on other sites More sharing options...
Noz Posted September 27, 2012 Share Posted September 27, 2012 if you cut the pipe off, it will fit. but you mentioned a gap between the two? Quote Link to comment Share on other sites More sharing options...
SarahJon Posted September 27, 2012 Author Share Posted September 27, 2012 Oops, misunderstanding. The gap being between the midpipe and the cat where it won't fit over that bit of pipe. Any idea if it would cause any sealing issues if we just chopped that bit of pipe off? Quote Link to comment Share on other sites More sharing options...
Noz Posted September 27, 2012 Share Posted September 27, 2012 Not if you prep the pipework first, as your use a gasket anyway? Quote Link to comment Share on other sites More sharing options...
SarahJon Posted September 27, 2012 Author Share Posted September 27, 2012 That was Jon's theory. Just wanted some second opinions before he started mutilating it! We will get it on come hell or high water!! Quote Link to comment Share on other sites More sharing options...
DuaneT.Turbo Posted September 27, 2012 Share Posted September 27, 2012 Grind the tube, use a gasket or hi-temp silicone sealant, jobs a guden Quote Link to comment Share on other sites More sharing options...

SarahJon Posted September 28, 2012 Author Share Posted September 28, 2012 Yes Although it's only been started on the drive so far this evening. It's just a nice purr, didn't want anything deafening this time! Had an RSR on our first Supe and it was awful, made my ears ring after more than about 20 minutes in the car... not good!

SarahJon Posted September 29, 2012 Author Share Posted September 29, 2012 Glad your happy with it mate Yep! Been out in it today and the growl is just what we wanted. Doesn't intrude into the car at all but nice and growly from outside the car - perfick!! We've bought Dean's (tooquicktostop) wheels from him too so once we get those from him in the next couple of weeks then the car will be starting to look a lot better as well as sounding better Quote Link to comment Share on other sites More sharing options...
