Downpipes and straight through exhausts

[MarkB]

I think you need to here flashyg's twin box system then.

Not sure how many boxes Leon is running but I don't remember it being that loud at Santa Pod.

[s4woody]

you dont need to go through MRC to get an exhaust system from RS fabrication..01295266655 the guys name is russell..or email him at russell@rsfabrications.com
they have made quiet a few jig's for the down pipes that you mite want..

[S4TAN]

Viper - that pic looks like a "3 single Milltek. I've just taken one of those off and put a Milltek Dual system on - produced a very noticable improvement in flow and the car just flies now, seems to "breathe" so much easier, turbo's spool up great and the power is instant. Sounds ace too ... (but I also have the Milltek totally de-catted d/p's)

[viperbl]

Just realised there when you said that S4TAN that I have the milltek downpipes, so no idea what I was banging on about RS4 stock downpipes before! LOL!

So if thats a 3" milltek sysem I should have 3" downpipes already???

[MarkB]

Nope, the Milltek downpipes are much the same diameter as the RS4 ones. Maybe a little larger but not much

[S4TAN]

Don't think so dude - the 3" I was referring to was the cat-back exhaust system in your previous pic. I think the d/p's you've got there are the 2.37" jobbies ...

[viperbl]

D/P's needed as well then ... right, back to selling everything I have to pay for them!

Anyone wanna buy my downpipes and exhaust if I go ahead? , oh, the cats are empty.

I'm sure you'll get people biting your hand off for them if the price is good

The exhaust can't be too restrictive if the car makes 551bhp.

Thats true, but Doug thinks it is, or at least I can do better ... so, that being the case, and because of how much I am flowing now I might get a little more out of it!

Thing is, I am very happy with this exhaust, the sound is perfect, not too loud, not to quite. Good around town and gets good comments when passing folk on WOT. So just hope I can match that in the next setup!

I have just invested in a Meth/Water injection kit as well to try and drop the EGT's and intake temps ...

Any dual system will be louder than the 3" system

Is the Duel system not 3" anyway? Just Duel more of the way along as opposed to going to a single pipe ?

I understand its going to be louder, and I can live with that, just no as loud as Doug's for example, I feel for a daily driver that could be too much...

[MarkB]

The larger pipe lets more noise out itself and leaves less space for noise dampening in the boxes.

Is the Duel system not 3" anyway?

The Milltek dual has 2.25" diameter pipes - only fractionally louder than the 3" single - but flows loads more and sounds throatier...
