Another thanks to Yellowshed and some great results
Discussion
Yet another thread to pass thanks to Trevor and yet another recommendation.
Fitted an excellent Alunox exhaust (professionally and courteously fitted by Leon) to an otherwise stock M400. 447bhp and 409lb/ft. Chuffed with the result.
Now to man-up and give it more than 50% in any of the first four gears.

Hi Mark,
Sounds great! I'm also in the market for an exhaust, have had a good chat with Noble Motorsport about it but am keen to learn the experiences of others on here. The Alunox system has been mentioned, are you able to let me know what work you had done, manifolds? remap? etc plus the outline cost.
Also, has it changed the sound, is it louder / better / worse than stock?
It would be great to see some pics too ;-)
Cheers,
Si

Good stuff, it's amazing how different it feels isn't it
About 2 years ago I had the Noble Motorsport exhaust fitted and got them to remap it. It does take a little while to get used to the extra grunt. It also let the engine rev beyond the 6000rpm that the standard car struggled with.

Very nice figures - mine was 436bhp stock with just the Roush exhaust (with 100cfm cats) so the Alunox one looks good.Fitted an excellent Alunox exhaust (professionally and courteously fitted by Leon) to an otherwise stock M400. 447bhp and 409lb/ft. Chuffed with the result.

I'll tag along with this,
Big thanks from me for Trevor again and also Dave and Matt for the hard work theyve put in, Jetstream guys took my car down at the weekend and by the sounds of things must have tried the patience of the gents with a cv boot wanting to go for a walk, a boost pipe blew off and knocked some fuses out then to add to the fun, the two Toyo R1R's on the rear couldn't get grip, overheated and dissintigrated, a set of Goodyear eagle f1's later and the results were 555bhp and 525lbft. Not sure the revs etc yet as I'm on holiday but can't wait to get home and drive it!
