ABP_Tardis_42 Posted July 19, 2009 Share Posted July 19, 2009 I am interested in buying an Invidia downpipe are there any exhausts I should stay away from because of fitment issues with the flange? The CBE's I am looking towards are either the magnaflow or SPT. Any advice is greatly appreciated. TIA Link to comment Share on other sites More sharing options...
ConeEluder Posted July 19, 2009 Share Posted July 19, 2009 Both of those have a donut flange, so you'll need an adapter http://www.fredbeansparts.com/servlet/the-2651/3-Inch-Downpipe-to/Detail Other than that the fitment should be fine. Link to comment Share on other sites More sharing options...
ABP_Tardis_42 Posted July 19, 2009 Author Share Posted July 19, 2009 Yeah I figured that I would be needing an adaptor after all the reading on doughnut flanges. Thanks for your help. Link to comment Share on other sites More sharing options...
NSFW Posted July 20, 2009 Share Posted July 20, 2009 Or find a 3" mid-pipe so you won't need on adapter... Link to comment Share on other sites More sharing options...
CTATV Posted August 16, 2009 Share Posted August 16, 2009 is the invidia DP 3 inches? its not a shorty DP right its the whole piece to the catback? Link to comment Share on other sites More sharing options...
KurtP Posted August 17, 2009 Share Posted August 17, 2009 Uh, arent all the newer SPT exhausts 3" mid pipe and y pipe going to 2 1/4 mufflers?

CTATV Posted August 17, 2009 Share Posted August 17, 2009 I thought the greddy was 3" at the mating point as well. never noticed a taper when I installed mine... Link to comment Share on other sites More sharing options...
tetsulo Posted August 17, 2009 Share Posted August 17, 2009 SPT v2 CBE is 3" mid pipe EXCEPT where it necks down to fit the stock DP using the stock donut. Buy an adapter, or cut off the end of the SPT mid pipe and replace with a 3" flat flange. I used this. http://www.rallysportdirect.com/shop/elite-awd-down-pipe-stocktapered-cat-back-adapter-p-3911.html Unfortunately tt wasn't quite perfect. I had to open up the bolt holes a little bit with a grinder and use some red permatex to completely eliminate a leak. If it doesn't hold, I saw that someone makes a 3" flange with about 3" of pipe made to weld on. Luckily there is an excellent TIG welder in my area who hooked me up years ago with my 3000 GT. I can't find the link right now which is ticking me off but I think it ran about $50 bucks or so. Link to comment Share on other sites More sharing options...
KurtP Posted August 17, 2009 Share Posted August 17, 2009 Well isnt that just a pisser. I guess Ill just have whatever shop I use straighten that out so its 3" all the way when I take in all my gaskets to get gasket matched. Link to comment Share on other sites More sharing options...

CTATV Posted August 17, 2009 Share Posted August 17, 2009 well I mated it to the stock DP for now (flat flange to donut) with longer bolts. Im in the process of getting catless UP/DP. On the search for a used one if I can help it. Link to comment Share on other sites More sharing options...
