It certainly is a Komotec Y pipe and part of their kit. Its my picture ! and is identical to their website photos. However whether it has any effect on the performance by being flattened is debatable, but I do not think it is a great design and seems to be a compromise because somebody could not be Arsed to design it correctly

Yep that’s the one Kristof , cheers

No I’m quite correct actually! It does look like it has been flattened down and no explanation why. No exhaust manufacturer would deliberately put that restriction on purpose on a pipe unless it was Poor engineering possibly?

Have you seen the system ? The Y Pipe presumably in order to fit around the car looks like a sledge hammer has been used to flatten part of it down. The Headers/Manifolds and Cat are fine

2 track days in and look fine. I did find the Cup 2 ‘s went off quickly on a warmer day and wore the outside edge more than is visible with the AR1’s. They Certainly have far more grip Time will tell but at 25% less than a set of Cup 2’s, the AR1’s look promising. Going to Hethel in a couple of weeks so will know more after that

Just sold all my spare Cup 2’s tyres ,as: I am now on Nankang AR’1s which are a far superior track and fast warm weather road tyre. Excellent grip, a tiny bit heavier and noisier than Cup 2’s and ok in light rain. As you stated PS4S would be the ideal road tyre choice but not available in any remotely useable sizes unfortunately

Right, that’s a bit of a pain ! I do have a QT 2bular but will be putting it back on mine this week unfortunately or could have lent you it

What’s the issue ? Problems with the Ti back box or just noise. If noise then Donington only seem to enforce the noise meter on the pit straight.

Wednesday

Just had 2 great days at Spa and Zolder, although was particularly hot in Spa. Was Using Nankang AR1’s which performed infinitely better than Cup 2’s, however did get EML warning on, but had use of an OBD reader and checked what might have been causing it. Fault was “System too lean at higher load bank 1” Could not clear the light as reader was not Lotus compatible although had a universal option, but after an hour or so with car in garage and out of the heat the fault just went away So anyone have recommendations for a Lotus compatible reader

You may well be right on the Nitrons but was pretty sure that when they dropped the price some items were then optional. Had a friend who bought a later 410 and it did not have 3 way, unlucky I guess

Just to be aware not all 410’s came with the 3 way Nitrons I believe

A 295/30/18 works perfectly well particularly AR1’s and AO52’s but not so good in damp conditions

I have a brand new set with stickers on etc. They are a late 2021 manufacture and I purchased them in Feb this year I have switched to Nankang AR1’s on my track wheels so will probably not go back to Cup 2’s If interested let me know

I had something similar on mine but the red redline lights came on simultaneously at 4,000rpm and wouldn’t let me rev higher. Fortunately at Silverstone and Ben got it in straight away to do diagnostics, but nothing came up. He wasn’t sure why and it’s never done it since.

You can do Anglesey, with no issue, Silverstone and Donington are ok so long as you short shift by the noise meters.. There are others but will need to be driveby as unlikely to pass any static tests unless a loud day

As stated this was in no way any criticism levelled at you and more directed at some of the folks who gave opinions as they are entitled to do but without perhaps fully understanding the situation imo. With social media you can be judged guilty unfortunately

Interesting read from Jim. I did think there may be more to the story than that posted on Eddies thread. I have every sympathy with what happened to his car, and it must have been a terrific shock for him. Although it does appear the back box which failed had been previously fitted to a written off car ?. If this is correct then while Jim may use strong language which not everyone agrees with he does have valid points. I feel for Eddie, however Jim runs a business and if these are the facts then he has every right to be heard and to defend himself. I for one do not wish in any way to criticise Eddie, but some of the folks who posted on his fb thread without knowing the potential facts

Why what’s happened ? Want to share ?

The biggest ongoing issue is when you take exhaust off and on a few times. The hanger bracket bolts screw to a very dubiously allegedly welded plate that has the 2 nuts on. The plate will eventually part company with the chassis and is them a right pita to line up

Good numbers, what about the Torque ? I had mine dynoed yesterday and it’s a bit of a lottery really with all the different variables, however the Torque was 389lbs ft which was better than I expected. Forged will add some longevity, good luck

What dyno numbers did you get on your car Matt ?

Minimum seems to be around £80-£85k The car came fully loaded but options I think worth having are : Sound deadening, Carpets, Harness Bar, Barge Boards and AC

I did all this research last year for my Cup430. Went for the Tubular Quiet system with rear cans. Then simple swap out of back box when not tracking it

I expect very few owners, me included who will sell in the short term but like everything, at the right price you can buy anything. Good Luck
