There's pros and cons to the various types of downpipe. There's an open bell-mouth (with and without splitter) and dual-dump pipes (where the dump tube joins close to, or far from - the main tube).

Open-neck pipes are claimed to allow earlier spool-up of the turbo and more low-range torque. Dual-dump pipes are said to give better top-end power at the expense of low-end grunt. Dual-dumps are said to be quieter as well, or at least can be quieter.

I went for a Scoobysport open-mouth downpipe, myself.

 

what did you think of the scoobysport, I am going for one of these at the weekend??

I've no experience of any other aftermarket downpipe, so can't really compare. However - a month or so after having the downpipe fitted, I've no regrets about my choice. Excellent noises (turbo and exhaust), early spool-up and good throttle response.

One benefit that I didn't appreciate in advance was that of listening to the turbo. The turbo becomes much more audible after fitting the decat d/p. You can hear it start to spin after about 2000 rpm, and quickly adjust to noticing how the turbo noise corresponds to the delivered power and, more importantly - the power the car is about to deliver.

The Scoobysport d/p had a reputation for being one of the louder downpipes. I've not found it to be excessively noisy at all. I've done all sorts of roads with the pipe fitted; A-roads, B-roads, daily commutes to work, long-haul motorway journies. In no circumstance have I found the car too loud or tiring.

My car has a full SS system, and also a Tek-2 remap from SS. The car now burbles nicely, and gives pops and bangs once the exhaust is warmed up. Nothing excessive, it just reminds you it's there...

 

Thanks for the reply's guys,

currently i have a Group A down pipe from TSL, just wonderd if they were any good?

and is it worth changing?
