Hi All,

Obstructing a Road when you are not a police officer is against the law and could be interpreted as Deprivation of liberty if you could not leave the area.

It is a public road and if he knew the first thing about skylines he would know that we do not use trumpet exhausts and generally drive together as a group for social outings not to terrorise the land owners.

While the first part of the post is well thought out, I question some of your mechanical knowledge and express that attempting to scare people away with theoretical violence often attracts the kind of people you don't want near your house.

Make a statement that is well thought out / well presented and we will gladly read it and take it under consideration, We are an open car community and the members are strongly encouraged to obey the road rules and be courteous to other motorists.

we active participate in community, charity and police events, And work hard to have a positive community Image so posts like these will get peoples backs up if in fact it is not one of our guys doing this.

HB: I can tell a fast car from a slow one, and an emptied out muffler (or sawn off muffler) do not make your car any faster.

CN: if anyone here has "emptied out" their muffler please raise your hand... And then promptly walk out that door >>>

HB: Noone enjoys a loud car except the attention-seeker who drives it.

CN: lies! I throughly enjoy the sound of a built rb cracking gate or a lumpy V8 idling away at a set of lights

HB: Yesterday night there was a car that sounded like a trumpet (the 1600CC kind), he wasn't fast, just loud, and lonely too

CN: yesterday night? You mean last night i assume, anyway. You show me a 1600cc skyline owner that frequents mt Nebo and I'll personally go and kick them in the nuts (heads up, there arnt any here so why are you harassing us with your drivel). Secondly, we usually travel in Teams, we're a social mob.

HB: The only "tuning" this pov could afford was sawing off the muffler of his car, which did 0.0 in regards to performance.

CN: Um sorry to burst your bubble tuning redneck king but simply removing the mid muffler from a standard xr6t system see's up to a 15rwkw gain.

HB: We also know the area and if required can drive these mountain roads faster in our 3 tonne Ford than you can in your Scooby Doo.

CN: well this sounds like a challenge now dosen't it...

Anyway, trying not to sound like a smart ass here but it's hard when people accuse us of stuff we more than likely had nothing to do with. Now i hope you go and post up this message on gumtree and ikea.com as it's about as relevant there as it is here...please Jog on Mr Billy

Time for some myth debunking, because false information like this might lead to more confused/misinformed people. Not only is your suggestion untrue but a mod like the one you propose would also make your car illegal. Legalities aside, I will focus on the power change here. First, read this thread, which talks about what you are suggesting (this applies to both stock and non-stock exhausts btw):

http://www.fordxr6turbo.com/forum/topic/10243-removing-centre-muffler/

Coincidentally, the thread is about the xr6t. People who have removed mid mufflers are reporting they lost power, ended up with a sluggish engine (due to ECU compensating badly). Removing mufflers is a noise mod, all it does is increase noise, it will not increase performance of your car in any way. Now, if you want to keep saying that removing the mid muffler from a xr6t will increase power, that's up to you but please read on before you do so.

Deleting mufflers might distribute power slightly differently, for instance, with a removed muffler you'll lose some low end torque ( torque is what you want btw, it's the good stuff ) and gain some in high RPM, but even those differences ( which are NOT power increased, just redistribution) are minimal and certainly not 15bhp.

Removing mufflers will increase airflow through the exhaust at the expense of air velocity. The more air flow, the less air velocity, and vice versa. A good exhaust will balance both for a certain RPM (you are tuning your car for a specific RPM, right?). A bigger pipe, or removal of back pressure, can result in a drop in velocity, which can lead to a drop in overall power due to the low velocity exhaust pulse not being able to pull out gases from the exhaust fast enough. There is some interesting reading on the topic here, I advise it: http://www.gomog.com/allmorgan/exhaustbackpressure.html. As for exhaust diameter, a double 2.5" exhaust is MORE than enough for a 500 HP car. ( or a single 3" if you have a 4pitter ).

Respect,

The Hill Billy

Edit: I'm happy to be proved wrong though. Just post dyno reports before and after deleting muffler.

Champ you obviously have no idea about the crowd of people you are talking to here, or understand anything relation to the way in which skylines are modded and the way they react to mods. If you have an issue with people driving up your road I'm pretty sure you have, or can find, the police phone number to give them a call when this is happening.

Making threats to random car forums certainly isn't your best move, and if something happened to someone it isn't hard for the police, let alone anyone to track your IP address and have all your details.

For future I suggest you do a little more than copy a fordforum article when talking about exhaust modifications and the way cars react to them. No one on here is driving a stock XR6T and removing the mid muffler...

And here are the dyno graphs you asked for, showing not only my claimed 15rwkw gain but in fact a 17rwkw gain

Coming on here and arguing Performance alterations of exhausts in Turbo cars of any nature (We all do our homework on any potential competition and/or our next purchases) is like arguing Theoretical Astrophysics with Stephen Hawking, The collective knowledge of any 2 people that have posted in this thread thus far is clearly sufficent enough to prove you wrong.

We are more than happy to accept a sheepish apology and converse socially with you afterwards.

can everyone please stop saying "we" when referring to the forum here? I'm on this forum and speak/think for myself just fine. Hate to break it to ppl, but there's hoons that drive skylines like dicks, and have excessively loud exhausts, not just commo/ford drivers. Same as every other car group. I live off a fairly main road going up a hill, and plenty of ppl drive cars with v.loud exhausts up it. It's pretty bloody annoying. I also drive cars with fairly loud exhausts.....so yes that can make me one of those ppl too. That's life, we're all hypocrites at one time or another.

I think the OP's put a balanced viewpoint forward. It's an awesome section of roads, very enjoyable for a spirited drive and best enjoyed with no other traffic in the way. He's acknowledged that. Driving on the wrong side of the road racing, I don't know how anyone can defend that. Dunno about his tuning tips but hardly a big deal, debate it if you want or just 'whatever' it and move on. I didn't take these 'threats' apparently made too seriously and thought it was done in a joking enough manner.

To the OP I'm most definitely not a supporter of the new hoon laws however, this sounds like an instance that could warrant their application. Video footage, details of incident, rego's etc, to the authorities wouldn't be a bad idea. Endanger only yourself? no worries, natural selection at work. Endanger others, say by driving fast on wrong side of road at night? no sympathy whatsoever and need to be removed from roads asap.

Remind the Simpson.

Oh dear, more myths.

Perhaps they "forgot" to mention that they remapped / flashed the ECU ...?

Btw, this will be my last post. Thanks again for the serious replies, and for spreading the word.
