I'm about to buy a new set of front pipes.

I've been told that they should have a flexijoint to reduce stress on the turbos

Trouble is I like the look of the Greddy MX pipes but they don't have the flexijoint.

UAS also have a stainless steel set with the joint for a similar price.

Anyone recommend which I should go for?

Anyone inspected the Unique Auto Sports pipes to confirm quality of them or otherwise?

Cheers

Who cares what they look like when they're under the car :thumbsup:

The hks ones I've got have a flex joint, I guess they wouldn't put it there if it didn't do something.....I know that's not the best theory on other parts

i was just in the same position myself this week.

I found it interested that everyone recommend the pipe have a flex joint but alot of j brands dont use it (for example mines :thumbsup: ) anyways i ended up going the HKS one because its one of the biggest available (70 to 85 mines is)

They are like 45,000yen brand new

this is the one I purchased for my 1993 rb26dett engine, $139usd

http://cgi.ebay.com/ebaymotors/89-02-Nissa...sQ5fAccessories

I also bought tuned-length manifolds from the same seller, http://cgi.ebay.com/ebaymotors/OBX-TUNER-T...sQ5fAccessories

all up came to around $450AUD delivered (for the OBX front pipe with flex pipe + obx manifold). for another couple hundred I got HKS dump pipes. :thumbsup:

not yet installed. looks to be EXCELLENT QUALITY

No need to take me literally mate :D

I was in a rush to post as lunchtime was ending

By "look of" I was referring to things like the size of the secondary pipes compared to the JJR type ones (60mm versus 70mm)

I rang the UAS seller after deciding to buy but his attitude and phone manner turned me off getting them (didn't like me asking where they were made (I figured anyway) )and I didn't care how shiny they were.

Thanks for the help everyone

they are ok, but big, heavy, hard to fit and expensive. design is ok but I'm not that sold on split dumps. they claim to help spool up but during spool up wastegate is closed so how does it make any difference? ideally you want to allow the gas to expand in the fastest possible way to help flow. big bell mouth type dumps do that nicely.

What do people thinkg about the Greddy dump/ front pipe extension? It has the split dump design on it

nengun-0085-00-trust-greddy-extention_front_pipe.jpg

Great! I had them on my car until i had to remove due to ride height issues (you wont have a problem in a GTR)

However, you want to "mod" the merge to 3.5", factory they are not quite.

That's what mine had done anyway.

Although that said, putting on stock ones with GT-SS's - i didnt notice a difference :D

Yeah I've got -9s going soon. Trying to get the best of everything (even using standard parts). I want to replace my front pipe (Trust MX) as its looking very worse for ware right now.

Price wise I don't see them as expensive really. Tomei dumps are what? $800 then plus a front pipe? $600?

I'm in the market for a new front pipe for my BNR32. I'm sporting BNR34 vspev outlets and I want a high flowing front pipe to match it.

Anyone know which design offers the best flow? 1) Equal length such as the Mine's

2) Short pipe such as the stock design, RS*R, etc?

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Duncan's V37.......race car?

      By Duncan · Posted

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
