    Relentless dp sports cat.. Slight dissapointment?Xs power dp an sports cat

    Right just few little problems i found after fitting mine yesterday.... Anyone else feel the same?

    The bracket which is ment to mount to subframe mount is hard against the subframe.
    Only option is to cut it off a realign!

    Secondly why pay out for a nice 3" system when it has that silly reducer to fit a standard system?
    It was like a cock in a sock.... So i had to weld another bit of pipe on so it fitted my miltek cat back. Which surely must be restricted? 3" dp an sports cat which then drops down to 2 1/2? 2 3/4". Then back to 3".

    Third an final fault is it hangs low under the car so it now scraps over speed bumps :'(

    Rant over. Lol.

    Other than that its a nice looking bit of kit and build quality is really nice. :-)

    Whats your thoughts?

    Sadly its fairly typical of Relentless's wandering quality control... shame... the are better than they were to be fair but I guess one or two slip through..

    The reducer is realistically to allow it to fit to the std system.... you can see why they did it... its difficult to cater for every aftermarket setup out there so the easiest way is to make it fit a std system...

    Have heard a few peeps suggest the lower bracket can be problematic...

    Mine fits like a glove... You sure you've done it right? :/

    Also, unless you're running 400bhp+ you really don't need more than 2.5" cat-back. The 3" downpipe frees up the turbo, lets it spool faster initially, but the difference between 2.5" and 3" cat backs (bearing in mind how restrictive cats are...) on even a stage 2 car is not noticeable. I got the decat version so I don't have that problem

    .

    Im happy with it overall just need to get it on the ramp an sort the bracket out. I may modify the pipe in future but if its not restricting the horses then its happy days. .
    Ill try an get a picture of how it hangs under the car, its like the angle is wrong off the flexi it goes downhill the back up. Strange.
    Thanks guys

    they do sit very low on the decat section.

    They seem to have a bend in there that I don't think is needed, mine sat very low like that and scraped everywhere, so I removed the decat section, and cut out the bend and replaced it with straight 3'' pipe and it sits much further up.

    Whether this would cause prop clearance issues with an S3 I'm not sure, worked a treat for me though.

    My front hanger also didn't line up at all.

    I assumed that it was to clear the prop on the S3, but perhaps not!

    Having spent two solid days fitting the damn thing my only advice is make sure you have a very good tool kit, a 4" angle grinder, preferably an air chiesel, preferably a ramp a whole lot of patience and ingenuity and a good mate. Loads of guides around, drop the subframe, undo prop shaft gain access through osf wheel arch etc. And don't bother if your in a hurry, ill equiped, have no patience or its your first mod

    For the record mine fits like a glove and the ceramic coating means even after a hard run its still cool to the touch unlike the catback lol!!
