Screamer pipe or into the downpipe?

[Jaswan]

Im about to start making up my downpipe and im in 2 minds as to leave the wastegate dump open (ie a screamer) or route it back into the downpipe.

What are your opinions?

Thanks

screamer pipes sound ace, but they are loud and can be a bit much. Ideally have one with a valve but it gest complicated and not a lot of space.

I've owned a car with a screamer but decided against it when building system for S2.

If it's a track car you don't want a screamer to stay within the noise limits.

And IMHO screamer pipes are just annoying on the road.

As Baz says if you plan on tracking the car then avoid making a screamer. I've learned the hard way by being black flagged at Donnington and Combe. Spectators loved the noise but circuit management have regulations that need adhering. Static noise tests are usually performed @4000 rpm approx a meter away meaning your within the db limit. Different when your on track going through the gears your higher up the rev range resulting in a increased exhaust note. Especially if you have screamer pipe.

Obviously sprinting the car at York or Santapod you can be as loud as you like.

Have you actually been black flagged stu?

My mates evo9 has a screamer and he does a fair few track days. Iv been to croft a few times with him and they dont seem to bother once you have passed the initial static test.

As also said i can see a valved system getting complicated . .
