Re: Hi-Tech Full Exhaust System Questions
Thanks anyway Noel,
I have not written off ceramaic coating or thermal tape as I have thermal tape on hand but from my experience with this it starts off lookin very smart but then turns to sh@#. For the heat sheild it would have the stud welded to the extractor when I get to that stage

Re: Hi-Tech Full Exhaust System Questions
Hi Guys, Augustus the X Trail here, Dad will confer with Jalal on the temp difference ceramic coatings make, he ran them on his rally car, huge difference in performance to, as the engine bay temps drop considerably.
On the 1.5 twin carb Ford KB laser project Dad had going (115 KW @ front wheel N/A) it was one of the major power gains to be made, best bang for your buck around. He could howl it through the scrub for 1/2 and hour at full noise and yet 10 minutes later actually hold onto the extractors.
He broke this system several times due to ground clearance issues and the top notch welder said that due to the self sacrificing nature of the coating it was the easiest welding job he had ever done!
So go for the Ceramic any day over heat shields or thermal tape, looks awesome last forever and will just work well beyond what you expect!!!!
Hi Tech coatings do the best job around, and the best prices to for the quality you get.
Best mod you will ever make if done on a decent set of extractors.
I'm getting the Hi Tech Single cat back system in couple of weeks, although it looks awesome, Dads getting it coated as the way we like to get Muddy it wont stay that way for long and it will help in increasing not only the life span of the exhaust, but my expensive diesel engine as well, and make more grunt as no soot can build up on the pipes it all goes out the back, cant coat the interior of the muffler unfortunately, but the rest will be done and it also improves the exhaust note, making it deeper but not any louder, due to the different resonance due to the coating. So lots of advantages.
Now I just cant wait to get it fitted, Yippee.
I just wish now that there was a full Hi Tech exhaust system for me!
Oh well Dad reckons when my engine finally needs rebuilding my front Exhaust sections will get a major upgrade including a high flow stainless cat, then watch me fly.
Dad want's me to be the fastest Diesel Exy on the planet once we go for the full engine rebuild, gunna go for a bash on the salt, cant wait. 
Anyhow gotta go, just had a bath  so time to get all Muddy again, Augustus the X Trail

Re: Hi-Tech Full Exhaust System Questions
Hi All,
So just for any uneducated people (like myself) who don't understand the principals behind exhaust upgrades but can appreciate the results they achieve.
What is the additional benefit of paying twice the price of the original Hi-Tech exhaust upgrade to the "full you beaut" exhaust upgrade that includes extractors and headers?
I can't really say I tow often (but that will be put to the test next week with a 2,000km 8'x5' trailer carrying excessive new furniture), or do many outback trips (just yet, give me 3wks when I go camping) but with the new large tyres I have going on (next week) and the bi-annual trips to Brisbane I have been encouraged to look into an exhaust improvement.
So basically, what extra advantages will I have if I immediately upgrade to the whole nine yards system? :-D
Secondly, I would have expected most people to get their local exhaust specialists to install such a system to their Exy. What costs should I be expecting in Brisbane for either install? And, is it worth holding onto any of the OME parts for ... I dunno back-up bush mechanics?
There goes some beer money 
Cheers,
Ben

Re:
Hi Ben,
The full exhaust system for the T31 is not yet available as yet, as Hi-Tech are still waiting to find someone with a Petrol CVT 2.5 T31 exy to model the extractors/headers on.
Only the T31 cat. back system is available at this stage.
The benefits of replacing your exhaust system is to free up HP which helps when towing for sure but it also gives you access to about 9KW extra power which comes in handy, not to mention the biggest bonus of having 10 years warranty with the Hi-Tech system which not even Nissan Australia can match on the factory exhaust.
Any muffler shop will be able to fit the system for you for a cost of around $250 but the cat. back system is very easy to fit as DIY Installation if you have access to ramps.

Re: Hi-Tech Full Exhaust System Questions
Thanks Jalal for the quick response.
Well I'm hoping to convince the Mrs to make a trip to Sydney and get the guys at Hi-Tech do it while we visit family. Before I consider that I intend on calling Lambros to ask what he would think of adding the full system for Petrol and maybe work out if we can test it.
It will come down to how much time I can get off work and how long it would take to play around with as we'll be taking the young kids with us. Hopefully we can then put to rest the questions regarding the Petrol system. Obviously there are a few people to coordinate with ...
Alternatively there are always a few helping hands up here that can help with a simple DIY system :-) I was pretty happy with the towing trip back to Isa from Brisbane, but I could have used the extra power while overtaking the slow drivers as the Exy wouldn't pick up too much speed with the foot flat sitting between 100-110kmh
Cheers All
