Front/Dump Pipe/Exhaust Help Hi guys. I want to upgrade my stock dump/front pipes and cat on my R34 GTT. I don't wanna go overboard. It's just a daily driven car. Right now I have a SR JASMA cat back exhaust. I think it's 3", but I am going to replace it with a Blitz Nur Spec cat back later on. Firstly, I would like to replace the front/dump pipe. I saw this on just jap: http://justjap.com/jjr-stainless-3-bellmouth-front-dump-pipe-nissan-skyline-er34.html JJR Stainless 3" Bellmouth front/dump pipe And this cat: http://justjap.com/x-force-3-stainless-high-flow-cat-nissan-type-3.html X-Force 3" Stainless High Flow Cat Question 1: Would these two pieces bolt up together? i.e would the flanges mate up perfectly? Or would I have to modify them? Question 2: When you put the pieces together, do you have to use some special silicon between the gaskets? or do you just use the gaskets they provide? Question 3: Is it very important that you need a tune after the installation, or can i just adjust my boost controller down a notch and all is well? Question 4: Would it be a good idea to wrap the front/dump pipe in Titanium wrap or waste of $$ and time? Question 5: What is the cell rating on that x-force 3' cat and is it a good buy for a daily driver expecting a little more power gain (with supporting mods in future ofcourse)?

Just want to clear some space. Thought I would see if anyone wanted this stuff before they go into the bin. I am in Sydney. All prices exclude postage. - $100 blown R34 gtt stock turbo with OP6 rear housing. This is ready for a reco, you know the drill. The shaft is bent and minor chipping can be seen on the exhaust and nylon compressor blades. - $60 JJR Split Dump pipe. Link to new item. This was bought to fix an exhaust leak. Soon after installing I found that the front pipe was also rusted through, so I bought the 3" bellmouth pipe from JJR. I had this installed on the car for 200km. It's like-new and comes with all the hardware, unused. Features a removable airflow splitter. - $5 Dump pipe heat shield. Will throw into box with Split pipe if you want. - $50 used oem coil packs for r34 rb25det. Working at stock boost. They have done 100k.
