20V CQ Tidy Up

[re2500]

Are you going to be running a 3" back box or smaller? As that will probably change thigs a lot. I can probably set the gopro up next time its dry and get some vids of my system if it helps. Mines 3" downpipe and 3" straight pipe back to the rear subframe and then its 2.5" over the rear diff into a backbox with internal perforated y pipe into two 2" tailpipes. In my opinion its nit droney, gives a lovely 5cyl howl on WOT over 4k rpm and a nice burble in idle.

Hadn't realised yours was just a single box mate, sounded really nice at ADI
I'm going 3" through to the rear axle then down to 2.75"

[re2500]

Single box is the way forward. IMHO i think youll find two boxes a little too tame

[DJones]

Mine is a single box, 3" turbo back, not that noisy and don't seem to suffer with drone..

[Error404]

Good to hear, my wallet would prefer a straight through

Have you got any vids of your Darren? I remember there was one of it on the RR a while back?

[Error404]

This ruby coupe is S2Spike's old motor - sounded the ******** IMHO.

Just like John said, inlet and outlet not in line on the system above.

Great welding btw mate

Lovely downpipe.

Is there anything this man cant do??? Well done Alex!

[G60Rallye]

Downpipe looks superb! I would go for 2 silencers, I run 2 on my car and its about right and easily passes noise tests.

Cheers guys
I'm erring towards a small 2nd silencer at the moment. Got a load more to do first so some time to consider, the rest of the exhaust will be the last job I think

Still if anyone has any vids of twin and single box systems to help me make my mind up that would be ace

I think it will come down more to the construction of the two boxes as well as the number, two 'cherry bombs' aint gonna do much compared to a proper 'silencer'. Have you thought about asking a local custom exhaust place for advice? They may help or may tell you to get knotted

Err on the side of too quiet, rather than too loud. BTDT.

Measure twice, and cut once.

Especially on a daily.

Best wishes.

Show us a pic of your jetex back box then
