I had a 2" systems custom made, a sports system and the sound is perfect nice and comfortable for motorway speeds but sound plenty loud on full chat,I replaced the cats with two silenced box's as it was still very loud, it is perfect and very usable still. About 107db static test at 4.5rpm

A wee video not the best sound but you get the idea.

I have the act manifolds and it seems a little quieter now.

I have a working switchable system on my Cerb, 93.8 dB (measured this week at Cadwell) with no cats, and around 140 DB straight through.

All self built, and all within the confines of the backbox area. I'm currently on version 2, still tweaking and making it better.

Any pics or more info on this?

Fancy building me one? Paid for of course - I don't know one end of a spanner from the other!

That's something that would be of interest to me also!
