I've just spoken to Roland about his GTT Sports Manifold, as I'm considering changing mine. I don't want anything to loud, and may just go for the exhaust re route on financial grounds. Has anyone got experience of either, and if so what do you think about your mod?

Hi!!

I've got this monster of a header and its freaking loud with my Megan Racing cat-back.
That race cat does wonders from Roland at GTT.

My advice is don't get it if you got a cat-back already... not that I know if its going to be load for your taste coupled with the stocker.

Will try to get the video of those babies in action somehow

Let me know if you can upload the video

Hi Guys, the GTT manifold only increases noise levels slightly, it is the various aftermarket
exhaust systems (ie cat-back) that can make these cars loud.That is one reason why we
dont make an exhaust system at the moment. If we do release an exhaust system we will ensure it has good silencing so that it can be used with GTT (or other) cat/manifold, whilst still maintaining sensible noise levels. IMHO it is the sports cat/manifold that will gain the power,not the catback system,so it is more important to have the cat/manifold.
ps The re-route is quieter than most (all?) aftermarket systems,so is a cost effective and
low sound level option that also is very good with our sports cat/manifold.
Best Regards Roland Gt Tuning

That's what I said in my thread about these two upgrades... the GTT header brings out the beast in the MR cat-back...

Hold on guys you will see something innovative on its way
To quiet things down a notch or two.

I have the GTT Header and cat, i have it running with the standard s exhaust,mine sounds nearly the same as the original unit on the motorway but maybe a little raspier around town also more pops and burbles I like the sound, not drowning and not hideously noisy like some!! i would defo recommend it.

oh and tig welded!!!
