Hey guys.

Might be a dumb question but I couldn’t find a definitive answer on the internet.

 

Im looking at buying an xforce turbo back exhaust in the picture I’ve attached but I don’t know if I will need to buy a front pipe (also attached)? Does the front pipe and dump pipe do the same thing or will I need both? 

 

Thanks for answering the newb question!

Hi Dan

you want the JJR stainless bellmouth dump pipe, which runs all the way to the cat...so eliminates the front pipe and turbo elbow, as it's all one piece. I tested the split dump pipe and JJr bellmouth-type dump pipe and found the bellmouth to be faaaaaar superior.

I also recommend just buying a Venom 4 or 5in metal cat rather than any ceramic cat they usually throw in as part of a package deal.

Hey mate!

Thanks for the quick reply. I’ve looked into the parts you mentioned. Does that mean if I buy them I will only need to buy a cat back system? If so, can you recommend one?

 

cheers

if you want my advice - and let's face it, who wouldn't :p - you should get this

http://justjap.com/jjr-stainless-3-bellmouth-front-dump-pipe-nissan-skyline-stagea.html?___store=default

which leads into this

and then, "cat back exhaust' is this - although, on the loud side so you might want something quieter...but then again, powerrrr

The ceramic cats are shithouse, so rather than buying one now, then changing to a metal cat that's cheap/nasty to save $50, i recommend just get a 5in. body Venom cat that you're unlikely to ever need to upgrade.

Hey mate.

 

thanks for the links! Do you know where I can buy any other brands for the cat back part of the exhaust? Haven’t been able to find any other than that JJR part that you mentioned above.

 

i don’t want to buy a full exhaust just to use the cat back section?

yes - you buy the JJR  BELLMOUTH dump (very important - don't bother with the split type, get bellmouth. Also, JJR stainless seem to be the best made/value for money), Venom cat (as recommended, pay the few extra $$ and get 5in body, rather than skimp now and want to get bigger in a years' time), and then you just need a catback exhaust. HEAPS of Jap brands available, which are usually all just cat-back. But they all get way more pricey. I only just recently got the JJR hyperflow catback which looks to be a knockoff of the HKS, but is in full (304?) stainless rather than 409>304. Was using a Blitz NUR spec previously which I liked, but the JJR is quieter (probs cos brand new) and unleashes more torque. Very happy with it for the price.

Hey guys,

 

So turns out that the JJR cat backs are out of stock for the next couple months (emailed the manager today) can anyone link me to somewhere I can buy a cat back?

 

cheers!

Don't buy, they are shit and way to loud. You'll be taking it to an exhaust shop to get another muffler put in to stop the drone. Scan Gumtree or Facebook sales for a decent Jap exhaust.

Hey guys.

So I’ve bought the JJR front pipe and bought a blitz Nur spec cat back. Just waiting for the cat to get delivered and I can get it installed! Just before I do, I’ve never seen this in an exhaust before. What is it? And can it/ should it be taken out?

 

thanks!

Quick note: that’s inside the exhaust tip 

It's a silencer.

 

IMO it's a bandaid for poor design.

 

Take it out and its louder, put it in and its quiter, quiter due to restriction.

      Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.

      Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.

      OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup

      Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
