Has anyone fitted the above product to their chimaera and if so what is the end result like sound wise and is it worth the investment ?
Was thinking of the cheap route of having "the offord" style exhaust modification but now considering going the whole hog and replacing the whole unit.
Any comments positive or negative would be helpful.

cheers

I don't know anything about this exhaust, but if it's a cherry bomb then most have a small core (not great for flow) and glass packed mufflers are old hat.

Loads of possibilities for exhaust, chambered or metal packed bullet mufflers are what most people run. You can buy them off the shelf and have an exhaust shop make up an exhaust for you.

Not sure on the configuration on the Chim. But it's either dual, which would need a cross over like a H pipe. Or it's a Y section with a single tube running to the back.

Either not difficult and shouldn't cost a fortune.

450Nick has one of these fitted to his Supercharged 450 Chim. I was around when he fitted to start with.

It will not make the car dramatically louder. But it is a true cherry bomb system with bullet style silencers, retaining the perforated sections. It is not a straight through conversion like others.

It does not increase volume too much, but makes the car much more throaty when put under load. You can cruise comfortably with it, and it gives a great sound when you want it to.

If you do a search on PH TV for ACT. There is a Pre Cat Griff with all the ACT trimmings on it, including the Cherry Bomb system.

If you want the volume as well, de cat the car. IMHO the decat + Cherry bomb system sound much nicer than the straight through sound. But each and every one to their own. The fitting and manufacture is also top notch.

My cousin (PH member Showcase) has just had one fitted (I presume it's the ACT one)

Sounds much deeper, and at idle sounds pretty similar to my Cerb which has a sports exhaust itself.

He said it's not much louder, but does now make a few more interesting noises. Not that expensive IIR either.

For what it's worth, I thought it was a good improvement. De-cat next ?

I went from standard exhaust, to Offord's cherry bomb, to ACT cherry bomb full exhaust.

The Offord's "Cherry Bomb", whatever it was, started louder and deeper, but "matured" over time to give loud, with lots of machine gun bangs and crackles on the overrun.

I had the ACT system fitted at the same time as the super charger, and it is almost a cross between standard and the Offord's mod. It gives a fantastic deep bass rumble, without the excessive noise on the overrun, although i'm not sure if this is connected to the SC fuelling? I do much prefer this option, but have only done a two or three thousand miles since this was fitted, so it may well change yet.

There will be a Thunder in the Tunnels run at the end of November, and if you can wait and fancy joining us, you can have a listen then?

Did you not like the Offord one then?

Initially absolutely yes. I had it for two years, but it got louder, and even louder, to the point where i was starting to think it was too loud. I then had the opportunity to have the ACT kit fitted for an extremely favourable rate, and went for it. So far, i'm very pleased, and think it gives the best tone so far.

It's definitely worth it. It's pretty easy to fit as well as it comes with a flexi pipe and in 2 pieces.

You can buy online now as well.

Got a quad exit recently fitted to the 4.3BV (Griff) with slightly bigger exit pipes than standard and its quite loud now (120.8db at 4,000 revs) but its the very deep bass tone on tickover that is more noticable (although it was deep before). Thought it may be too much but only extremely loud when giving it some beans.
