Exhaust question
Discussion
I wonder if anyone can shed some light on this...?
Now it seems that by removing the baffles (sleeving) the exhaust on a Rover V8 engined Tiv apparently helps the "breathing"... as well as making it sound rather
So... I'm tempted to do the same to the S (it's no longer loud enough, I think I'm going deaf!
) ... but then someone said the Cologne V6 "needed back pressure"... er..? 
Now depending on who I speak too, some say it will make the car lose power, others say it makes no difference, and some say it will help breathing... So who the
is right...? Suggestions on a postcard please... or just post here..
Removing exhaust baffles on a Rover V8 to help the breathing actually does the reverse in some cases and loose power. Been there, fitted an extra silencer.
The problem is that it is very car/exhaust specific. Some make no difference what so ever. Others can cripple the engine.
They do like a bit of back pressure.

OK, so where does that leave the V6 S then...?
Best left alone? (If it ain't broke, don't fix it)
With exhausts and silencers there seems to be a bit of a "black art". Exhaust systems and silencers are carefully designed to suit the specific engine,size, power output, length of system etc.
To simply remove the baffles would IMHO be a dangerous thing to do (a) some back pressure is often needed hence the baffle design (b)the sound plus probable backfire would be rather "loud".
If you simply want to make the car sound different then tuned sports exhaust systems are as we all know available from several sources. If its just a "sound effect" you want then one(two) of the "cherry bomb" silencers would give the effect but make certain whoever you get them from match them to the car.
Hope this may help - still non the wiser !!?

. I'm sure most of you know this but for those that don't.
A straight through silencer like on the " S" is as it implies,usually a straight line pipe in and out, no baffles in the box but an absorbent material surrounding a perforated tube as it passes through.
A baffled silencer has "baffle" plates (perforated), across the inside of the silencer and the exhaust gases follow a bit of a torturous route, sometimes in on the left and out on the right (like most saloon production cars).
If it was possible on a "straight through" silencer you could drop a golf ball in at the manifold end and it would come out the tail pipe, with a baffled silencer it wouldn't.
For those that don't play golf a marble would do !!
Sorry to go on about it, just waiting for the rain to stop ??

Sorry boys, I think the loudest S I've heard is owned by Psychobert...
... now there's a challenge for the S Meet !!
OK.. Don't know if its the loudest, but it is certainly distinctive. Oh
Psychobert,
I 've been musing over replacing mine, and was thinking of RT Racing in Sheffield, is that where you got yours ??

Nope, done by a company called Blue Flame. They weren't keen on doing any others like mine as it took them a lot longer to do it than they'd planned and they ended up loosing money on the job. Ascar in Sheffield have a good reputation; they may be able to make up a copy from seeing mine. Happy to put it up on ramps sometime so it can be looked at and measured up and so on..
Remonds me, meant to get back to you about brakes.. Griff 500 discs, calipers and pads were just short of £300 from Joolz, and another £35 or so IIRC for braded hoses. Really transformed the braking power of the car..
