Re:


Hi Ian,

Based on personal experience of having a T30 auto with the full exhaust system, I can tell you that while it didn't make a difference to the behaviour of the cruise control, I found myself not using it at all in hilly areas, I wanted to enjoy having full control of the accelerator and the power under my disposal, so while previous hill climbs were boring, after the exhaust upgrade they became much more enjoyable due to the power & torque increase even with the standard automatic transmission. I can only imagine the feeling of a manual powered T30 emoticon

Re: Hi-Tech X-Trail Extractors/Headers & Full Exhaust System (T30 X-TRAIL)


Hi Ian,

It all relates to where you are in the power/torque band and the steepness of the hill. A slight incline might not make the auto transmission change down with the added torque available but a steeper one will.

Also, the rate of change of the gradient also makes a big difference to how the cruise control reacts. There is a normal delay to sensing the change in speed before the cruise control starts to accelerate to maintain speed and sometimes the difference from the set speed can be large enough to require a change-down of the transmission to maintain speed. This is just the way a cruise control responds differently to how we react ourselves as we have the gift of sight and intuition that allows us to slowly add pressure to the accelerator before the incline increases so that speed is maintained more effectively.

Re: Hi-Tech X-Trail Extractors/Headers & Full Exhaust System (T30 X-TRAIL)


Hello Jalal sent you a PM regarding a full exhaust system...

I was checking the Catco website and I feel that everyone should download the pdf file Solutions Manual.

Initially when I saw the " how catalytic converters are made " video on the Catco website, they mentioned ceramic core wound in high temperature paper...that threw me off a bit...

On reading the Solutions Manual I realized that they are using different kinds of substrates and the one used by Hi-Tech is the metallic foil substrate.

I know you did mention on the first page that they are using the 200 cell technology but maybe if you include the words " metal substrate " then it will be more helpful to first time visitors...just my 2 cents!!

Also this explains why the initial cost of the Hi-Tech system is too high! They are using the best material and not cutting corners!!

Jalal do also provide more details regarding the ceramic coating, is it just on the outside or do they also do it on the inside of the tubes?? If it is only on the outside then I suggest you ask them what it will cost to coat the insides of the tubes as well.

Maybe that will be another option at an increased cost I assume!!

Now just waiting to get this full system!!! emoticon emoticon emoticon emoticon

Re:


Thanks Barry,

I thought the word "stainless steel through-out" for the CatCo Cat. Converter was enough information to indicate that it has a metal core, but I took your suggestion on board and added the metal substrate to the description.

The ceramic coating is only done on the outside of the headers and this is more than enough to eliminate any heat dispensation.

Due to the high cost of ceramic coating, Hi-Tech will not be offering having the headers ceramic dipped (inside and outside) as standard and this will only be priced as "special request"

I don't think you need to go to that extreme to be honest.

Re: Hi-Tech X-Trail Extractors/Headers & Full Exhaust System (T30 X-TRAIL)


Thank you Jalal..I just felt using Catco's exact words is better since it eliminates any issues later on and situations such as " you said he said "...

Noted regarding the ceramic coating on the headers. Since Hi-Tech is using stainless steel there really isn't any need to coat the insides of the tubes. If they were using mild steel, then it would be advisable to coat the insides as well.

Jalal I put in a request for pricing, shipping costs etc. Hope to get a reply soon!!

Re:


No problems Barry. Hi-Tech will never use Mild Steel with any of their exhaust systems, as they consider such product inferior when it comes to achieving results and when providing 10 years warranty on all of their systems.

I received your pricing request and sent it off to Hi-Tech to confirm the shipping cost.

Re: Hi-Tech X-Trail Extractors/Headers & Full Exhaust System (T30 X-TRAIL)


Hi there are Hitech still in operation ?? I sent an email days ago for info and no one has replied.

I would like to fit the system but start with the twin pipes at the rear and add the extractors later.
I just need current prices and how to order the items.
Your reports on the system plus photos was excellent. emoticon emoticon

Re:


Hi Ted,

Hi-Tech showed me your enquiry on 27/11 and I have asked them to respond to you directly. Please send them another reminder email.

I pulled myself out of their operation, as their response times are not as it used to be.

P.S. The pricing for Full Members is shown on the first page of this thread, so you just need to get the freight cost from Hi-Tech.
