Chris Tullett has asked me to post this up for him, nothing in this for me and you will be dealing directly with him though I will answer questions where I can.

Chris has developed two systems on my car, which I've tested and am very happy with.


2.5" Equal Length 4-1 Manifold £388.38 + VAT
2.5" 100 cell CAT Downpipe £297.96 + VAT
2.5" Silencer/Link Pipe £392.66 + VAT


3" Equal Length 4-1 Manifiold £398.14 + VAT
3" 100 cell CAT Downpipe £320.17 + VAT
3" Silencer/Link Pipe £402.66 + VAT


The workmanship on his products is second to none, the quality of the welds are fantastic. The 2.5" manifold is of full equal length (as is the 3") so will perform as well as, if not better than the TMS £1,000 version, (which Chris made but did not design). His design is much simpler allowing for a lower price and importantly greater clearance to the boot face.

Chris has generally made very few off the shelf systems as all his work is custom one off projects for race teams, world touring car, historical F1, manufacturers, DTM teams etc

The 3" system which I've run with for a while sounds fantastic, and is sensible in the volume it produces (max 96db tested before it had run in) and should have no problems passing noise tests on track.

Both systems can be made repackable as a cost option (although after opening my first back box up it was all as it should be).

Both systems are also extremely light, I don't have the figures to hand but I think they are the lightest out of any available for the VX. iirc my 3" system was less than half the weight of the standard system.

The above prices are valid on the basis that at least 10 full systems are ordered before the end of May. After that prices will rise by 15%.

There are lots of photos of the systems at:

Looks good and excellent value. What diameter and length is the rear silencer on both the 2.5" and 3" systems, if different? I like the look of the perforated/silenced tailpipes as well, wonder if that makes any difference to overall volumes.... Are you running a Stage 2 SC setup on your car yet, Muncher and wonder whether that makes any difference to the tested volume?

Silencers are the same size on both. I think it is 7 inches by approx 31 inches. Although it is straight through the internal pipe is run at an angle to maximise its length.

The tailpipes certainly make a difference according to Chris.

I'm still at stage 1 but I have plenty of reasons to believe that the difference in volume between the two levels will be insiginificant. It's also much more about the way the exhaust gases resonate at various rpms producing different tones rather than the sheer volume of gas that is going through. For instance the peaks in volume seem more dependant upon constant throttle/throttle position rather than engine speed. I'll be going to stage 2 as soon as Jon can fit me in, probably a few weeks time.

i think you should lend me your backbox next week and i will get a sound test

[savvy]

Will he be making a 2.25 system?

[Jameshs]

How loud are these systems??

[Sticky]

Will the 4-1 manifold bolt directly onto my Miltek system?

[alanoo]

Guess I'm stupid but I didn't saw this topic before.... but well, already ordered my manifold from Chris by mail Top service

[Muncher]

Yes.

The 2.5" system hasn't been tested for noise but it will be quieter than the 3" system which was initially tested at 96dB @ 5,500rpm. Paul CP has just ordered a 2.5" system so we should get some noise readings for that fairly soon.

Paul seemed to think it was just slightly louder than his Miltek, with a deeper sound, which is not surprising as it's a whole 50% larger in terms of diameter.


There's not much point in producing a 2.25" system really.

Wouldn't the 2.25 suit the n/a perfectly?

I have the same question, is 2.5" not too much for a mildly tuned N/A, I mean, for a non-SC sub 200 bhp engine?

Given the tight bends 2.5" is fine. I remember speaking to Jon @ Courtenay during the development and he said 2.5" is fine and not to bother with anything smaller.

I have heard that you would lose power applying anything more than a 2.25" system. Would this be the case you think if the 2.5" system was applied?

If that's the case, I'm ordering a full 2.5 system with manifold for my 161bhp N/A

It is a sexy bastard.

[savvy]

Sure is. Worth selling the vse for!

[182ian]

I am no expert at all so if i am well and truely wrong just say but would the first 180 degree bend not be more effective as a constant radius rather than two seperate bends, or could this be due to clearances with tyre?

[savvy]

am i right in assuming that the 100 cell cat with chuck on the eml light? how does it fair with the mot and emission test?

[rcvaughan]

Would have thought so! My 200 cell cat does sometimes! Should be OK for MOT though I'd have thought but can't be certain. Has Chris or Muncher tested it? (I might have a brand new unused cheater for sale soon )
