95supra Posted July 22, 2011 Share Posted July 22, 2011 Yes I have been searching but this is kind of urgent lol. I am meeting with a guy in 2 days, he has two downpipes for sale and I will be buying one. He has a used modified 3" downpipe direct bolt on for JDM twins. or new 3" RMM downpipe for American Supra's. This one should need a 2" restrictor ring. Also it is a bit cheaper. So my question is. If I run a DP with restrictor will this be ok? or would going with the JDM downpipe be a better choice? Quote Link to comment Share on other sites More sharing options...

If you've got an export spec supra the jdm downpipe wont fit, if you've got a jspec supra the RMM won't fit. If you've got an export spec supra (US) and buy the RMM downpipe you wont need a restrictor as you won't have the sh!tty jspec wastegate/s.

95supra Posted July 22, 2011 Author Share Posted July 22, 2011 I have a JDM RHD 1995 Supra TT 6-speed sooo the RMM downpipe will not fit? Can I just get the 2" restrictor ring? will I be better off getting the JDM downpipe then? I like the RMM one though lol. Quote Link to comment Share on other sites More sharing options...

You'll be better off with the JDM downpipe yes, seeing as how you have a JDM car. If you get the RMM downpipe he is selling it won't fit. Also if its for a US spec supra it'll be for LHD. As for just getting a restrictor ring, unless you remove the cats I can't think why you would fit one. Just buy the JDM one and run your second cat or a restrictor ring INPLACE of your second cat.

95supra Posted July 22, 2011 Author Share Posted July 22, 2011 I am also removing the 2nd cat with a 3" HKS midpipe, forgot to mention this. I would like to ideally be around 400bhp+ so I know this will require a full de-cat. In this case should the JDM downpipe have a flange in it so the turbo's don't overboost as they are expected to?

Homer Posted July 22, 2011 Share Posted July 22, 2011 Read this: bpu You'll need a restrictor ring to hold back the boost. Quote Link to comment Share on other sites More sharing options...
JMB Posted July 29, 2011 Share Posted July 29, 2011 Hi ! I got a 98 JSPEC SUPRA. As it is specific to the RHD, what downpipe should I buy ? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 29, 2011 Share Posted July 29, 2011 If it's a VVTi they use a specific first de-cat pipe, which I sell, but am awaiting pipe bends to make some more. Or I can sell you a none VVTi turbo elbow and you can use a normal none VVti first de cat pipe. Quote Link to comment Share on other sites More sharing options...
JMB Posted July 29, 2011 Share Posted July 29, 2011 I think that it's a vvti. I'll be interested by this first de-cat downpipe you sell, and i'll complete with an HKS mid pipe. I'll buy some gasket to make it clean If you "build" them, I'd like to have a 2nd sensor plug on the de-cat so I can put the OEM one + an AFR.

Chris Wilson Posted July 29, 2011 Share Posted July 29, 2011 I will be making two of these within the next couple of weeks. I can add an O2 sensor ring and a blanking plug, no problem. It will bolt up to an HKS second de-cat pipe. Is your car RHD? Quote Link to comment Share on other sites More sharing options...
JMB Posted July 30, 2011 Share Posted July 30, 2011 Yes it s a rhd ! Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 31, 2011 Share Posted July 31, 2011 I have found a VVTi first de cat pipe at the back of the shelf if you want it? E-MAIL (not PM please) for a price and delivery. So you need a restrictor ring, too? Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted August 4, 2011 Share Posted August 4, 2011 I could have sold you one of mine, I thought / assumed you already had one. No worries if you want one of mine, I can get it off this week. Price is £105 plus £18 P&P to France. I have one in stock. Thanks Quote Link to comment Share on other sites More sharing options...
