Anyone got one? What do they sound like? Much better than standard or no real difference?

I have Janspeed on my P38, sounds great, but not too loud, I would highly recommend them!

OK, thanks! It's that or remove the centre box, but the backbox has a hole in it so could really do with replacment!

i have the janspeed stainless y pipe back very good quality and fit.
on the v8 dont remove the middle box as it is important for back pressure and performance tail can be removed and tubed instead

Really? I’ve been told by quite a few people to remove the centre box but leave the backbox on! Weird...!

I have replaced my p38 exhaust with a Janspeed cat back system as others say not loud, can hardly hear inside with the windows closed, but in a tunnel and the windows down

Insurance company loaded me by £23 for the privalage though.

I think if you have cats fitted you need back pressure, but without free flow is good
