D Stock remain in g-stock?
remain in g-stock?
i was at Euro-tek today and they offer a type of upgrade to the exhaust by cutting off half of it to make it more free flow and louder..i was liking this "upgrade" seeing as it was only 150 bucks...if i were to do this. would i remain in G-stock? i doubt it somehow, but technically its still a stock exhaust...i guess i just want it to be really bad.
Thanks
Marco

If your talking about the one-ball mod then it won't effect your g-stock status since according to the FAQ Any exhaust from behind the catalytic converter and back may be used.
Also if they are charging 150 you might want to look else where. I got this done for $95 and in hawaii everything is overpriced so I would expect any decent muffler shop on the mainland to be able to do it for 80 or less.
If this isn't what your talking about then I have no idea.

any thing that connects to the cat and then exits the car from the orig cutout on the rear bumper. For example you can not exit the pipe on the side of the car under the door (like Viper). You can not exit the pipe from the side like the MC. It must exit from the same area the MCS twin pipes exit now. Also some areas have a Db restriction (incase you thought of running streight pipes).
But Justgo4it is has a good point - there is a lot that can be done.

What is your source of information? I'm taking the liberty of posting a section of the rule book. If by chance I have missed something please enlighten me. The limitations you mention aren't in the text of the rules. Garfield runs a Supertrapp on his MCS, whidch exits in the same location as a standard cooper.
13.10 ENGINE AND DRIVE TRAIN
E. Any part of the exhaust system beyond (downstream from) the
header/manifold or catalytic converter, if so equipped, may be
substituted provided the system meets the requirements of 3.5.
Stainless steel heat exchangers are permitted only if the physical
dimensions and configuration remain unchanged. Modifications of
any type, including additions to or removal of, the catalytic converters,
thermal reactors, or any other pollution control devices in
the exhaust system are not allowed and the system must be operable.
Replacement catalytic converters must be OE if the vehicle
has not exceeded the five-year/50,000 mile warranty period as
mandated by the EPA. Converters must be of the same type and
size and used in the same location as the original equipment
converter(s). This does not allow for a high performance unit. If
the vehicle has exceeded the five-year/50,000 mile warranty
period, replacement catalytic converters must be OE-type as per
Section 13.
3.5 MUFFLERS
Adequate mufflers are required for Solo II events. The criterion of
“adequacy” is not what the exhaust system consists of, but the sound
level. Any car deemed by the Event Chairman or his designated
representative to be excessively loud shall not compete without
acceptable modifications installed on the car.
3.3.3 Safety Inspections
--B. Inspection Requirements
----13) Exhaust must exit behind driver or to the side of the car.

Brian G. does legally run the supertrap out the side as your picture shows. However, at a national level event there may be a protest due to the "cut out" that is either made manually or occurs from the exhaust pipe burning away material. Brian took a new rear trim piece with him to Topeka this year to ensure compliance.

Here's what I posted when I got it done.
Unless your handy with a welder I wouldn't want to try this out.
Well on friday I got my MINI one-balled. And since then have put around 200 miles on it.
For the sound, it seems to be a bit louder but nothing excessive. Also the gurgling noise is louder, more frequent, and a bit sharper.
Didn't have a scale but I figure weight saving was any where from 15-20 pounds.
Cost was 95 dollars, they didn't like how little room they had to work with between the body and the pipes for the welding.
As for power its to hard to tell. Given that it's almost impossible to notice anything less then a 5% change. It would have had to cause about a gain of 8.5hp for me to notice. So is there any? No idea but I like the sound more and I figure I might have gotten a couple from it.
Anyway I should be at the next HMMC rally/event if you want to hear it.

RE: Supertrapp

Was he going to rearrange the 'trapp to come out somewhere else or just lower it? I think it would be classified as a "Weenie Protest" IMO.
Dou you think you could get a 17" SuperTrapp out the middle if installed on a severe angle?

one muffler mod at home
There are at least two suppliers that sell an elbow, mandrel formed to do the one ball your self.
One is nice shiny polished stainless, (about $175) the other is just stainless (about $125). Both appear to be properly sized at each end for the pipe sizes, which are different.
I paid 125 for mine. It came with some nice Tbolt clamps, not the typical ubolts and saddle. It is two stainless formed pieces welded together, but the weld is rusty. I have it sitting next to my helmet bag, and will probably put it on this spring.
I am hoping to hear some one elses so I can make a final decision.

one muffler mod
First let me apologize if I got one of your names wrong. I cant see the name of the person I am responding to...
Yucca patrol
I went back and read up on the Power plant, and it says they went to some trouble to make sure the exhaust had a deep note. That is not their exact words but it is how I interpret it. So I am thinking that cutting off one muffler makes it sound higher pitched. I seen some posts that say it is easy to accidently make a MCS sound like a CIVIC. does this sound like what you have heard?
Ratah.
I am sure many muffler shops do a good job, and use the right parts. The vendors "tout" their products as having smooth, un wrinkled bends, and being all stainless. If my local muffler shop used their usual grade of pipe, I would be back in there in 24 months for a new pipe, the way I am with my older, Not stainless steel pipes car. That is why I chickened out and paid for the stainless part.

exhaust mods
No, I have not done the one ball mod on my car yet.
In the group I "compete" with, cat back, or a CAI are one point. I am allowed 2 points. A sway bar is one or two points. I have not been able to figure out what will give me the most benefit yet, and once the "one ball" is done, it will be hard to reverse. I am leaning toward the handling work, and will entertain offers for the pipe I bought.
