Hi all time to replace the rusty exhaust on my '98 4.6, I'm going to replace the cats with double S 200cpsi sports cat but undecided whether to go with a Janspeed cat back or double S quad outlet cat back stainless steel exhuast. I dont know whether there is much difference between the two other than the price, £432 double S, £499 for Janspeed so any input would be useful and also trying to find a great sound to compliment the V8.

Very happy with the Double S cat back system I bought for my diesel, but mine replicated the original as I wanted quiet.

Back in my early days with my RR I looked a SS plus Rimmer's and Janspeed systems on the traders stands a Billing for future reference, the first two were [swivel pins] with poor bends with creases, thickness of the metal and welding in fact a load of rubbish at £250 but Janspeed stood out with its perfect bends, welding and its weight.
Years later when my disco exhaust back box failed what did I fit... a Janspeed cat-back system it was a perfect fit in length, bend angles and the position of the hangers, so just half hour to fit, that was 6 years ago....perfect.
And sound is no louder than the factory system although the exhaust note is a lot deeper....perfect.

The Double S I fitted seems to be heavy gauge & well made, it was a perfect fit too.
At my age, I do not want to be having to replace it again and I intend keeping the P38 until they bury me

Are you going to be buried in your P38 because it will get you out of any hole?

Had a janspeed on a rrc. One of the tubular headers rotted after a couple of years, thin construction mild steel. The rest was stainless, y piece mid and back. Mating flanges required exhaust putty. They were welded too far back on the tube so there was a 5mm gap between the flanges when the tubes mated. Poor

Not sure I would trust it to get me out of any hole and it won't fit in the crem burner

We start to think along those lines as we get older :lol: (70yrs. tomorrow in my case) although my RRC, the last of four that I've owned, is still on a mild-steel system. This is largely because a neighbour from years back fitted a SS system to his 3.9 & it sounded so cheap & nasty that I vowed to stick to the standard product! Because I never do short journeys (not used as a daily driver) only the rear section has needed recent replacement in the five years since the whole system was fitted.
