Debut New Product- 'GTT Stealth Sports Cat' (R56 MCS)

[roland2003]

Hi, yes it passed all MOT emmisions with good headroom to spare. I did put the figures up on M2 at the time...They were certainly cleaner than most 'sports cats'.
We can sell these with surcharge, refundable on return of a good stock ubit. But the surcharge has to be the replacement cost from BMW ..IIRC around £400

£400?! Jesus that's steep.

I am very interested in one of these, but at £171.35 (inc VAT) another £400 as a surcharge means I am not going to be able to afford one - I realise that this is refunded, however the money will still be out of my hands for a period of time while I get the new cat fitted and the old one removed to post back to you.

Fitting at GTT is not an option either as you are miles from Newcastle.

BUMP

Would be great to hear from a few more people that have had this done and how things are going as this is a mod im considering in the near future.

I didn't get it from Roland as i am in Aust, but going from the description he gave i had a local provider make the changes to the cat and i have never had a light come on in 2.5 years. The difference in driving is immediate with extra raspy noise emanating from the rear. I already had the JCW tuning kit fitted so it already sounded quite good. As the system got older and more track days went by it started to sound quite like the Challenge cars. As far as power goes, I had (as mentioned earlier) the JCW TK, plus i had already fitted the ALTA IC. Best bang for buck is he IC, over the JCW KIT, but that really added a lot of low down, push you back torque and some power gains. The GTT Stealth seemed to add more top end free revving power. Its a nice balance between the IC and the GTT mods they seem to balance out the torque-Power curves. Hope my opinion and experience helps.
PS the Unichip after both mods was excellent as well.

Oh and 400 is probably fair enough if they are doing the job and fitting all in one go. Its a bugger of a job! Put a 3" system through with the resonator deleted while you are at it.

Ive finally got around to doing this mod and while i was there i fitted a Milltek cat back system as well

The difference is immediately noticeable! It sounds a bit deeper in the car and a nice tone on the road plus it pops and growls on over run
The car is a lot more responsive, quicker and feels more free revving throughout the whole range. Im hoping with my ITG filter and the new exhaust set up its up around the 200 BHP mark, certainly feels it but need to get it on RR.

If you're thinking of doing this then i can highly recommend it!
