Roland Gtt on the forum is working on some amazing toys to give more power along with the TMC box Tony. Give him a shout, he just got 195 bhp from a A500 with our box  ;D

    Also, they fitted it too ;)

    And gave me back my old system which i flogged :-)

    Have you noticed an improvement appart from the noise you wanted? I thought a whole new exhaust system would add around 10bhp but it was mentioned only around 2-3bhp. It was also mentioned that the engine feels more free, does this mean it opens up easier when the right foot is put down  ???

    Well, I had the zorst done I also had new TMC settings.

    My AGP at the time was running 189bhp / 219 lb-ft

    So thats a 34bhp increase after the exhaust + TMC. So technically on the SS could be running around 214BHP  ???

    Can someone please explain to me the difference between a Cat-Back system and a system with a sports (hi-flow) cat and if anyone has had a system fitted with powerflow with a sports cat give me an example of the price  ???

    They quoted me £450+VAT for the Cat-Back system but don't know how much more it would set me back with a sports cat added to the system.

    Cat-back is basically a Backbox - Running your standard Cat which is probably pretty restrictive.
    A full system replaces the standard cat with a high flow system so gives a few more horses :thumb:

    Every Powerflow is different, but i paid £300 for a cat back...

    I will be getting a better cat asap to free up some more ponies.

    Cat back is from the cat back which includes down pipe coming off the turbo then the middle section n finally backbox

    If youve got an SS then I dont think you would feel much difference if you had a sports cat as it has a more free flowing cat than the standard agp anyway. Sports cat probably a £150-200 more.

    Yeh I've been quoted £790 including VAT for a full system, slightly fatter pipework, 3" twin tailpipe and a sports cat  :thumb: wondering how much difference this is going to make to my AGP SS TMC if anyone else has done something similar it would be good to know what improvements were achieved.

    This is the pic of the tailpipe and my car if anyone can photoshop them on for me to give me an idea what it will look like would be appreciated  :thumb:

    I just had cat back I don't think i will bother changing the cat as I don't think will make much difference. The engine did seem more happy and less restricted when I had the exhaust.

    if I'm honest with the standard exhaust I thought the car always felt restricted like you could feel it holding back even at 10000miles which is when I decided to get the stainless since then car seems much better
