Baddest exhaust for 2.0?

[CarlosZ]

I've a GD 2.0 with 40 IDFs, web73 and an empi muffler that is falling apart. I personally like a dual in dual out look but haven't found anything. What is the baddest (best) exhaust one can get? Don't really care for stock sound, need some noise to please the butt dyno. Thanks for any advice.

[Xevin]

I've heard good things about this. And the negatives is, its loud.

When I saw the title of the post I thought you might also want to know the goodest. Once I read it I saw with the empi, you found the ugliest.

so you really want the meanest and baddest? Click the link and see what you can't afford because you forgot to add the work "at a bargain price... and keep my heater too":

What kind of heaterboxes are you using?

[CarlosZ]

I don't have any heater boxes. From what I've been told I'm running stock heater boxes that have the outer material melted off. They look like basic headers at this point. Can't tell what they're actually from or if what I've been told is correct. It also came with a crappy empi exhaust that's coming apart.

The Python exhaust looks nice, but looks like it'll get in the way of valve adjustment and I don't like the single muffler to the side look.

I like the look of the VS 155-208-035SF. Is there any performance difference between a single muffler like the vintage speed (that negates the collector/header that is between the muffler and the heater boxes) and an exhaust similar to the Python that has headers after the trapezoid flanges? Not sure if my exhaust lingo is correct. Does anyone know where VS is made (hope not Taiwan/China)and what the difference between a CJ and CU header is and if there will be any noticeable performance difference between those and stock?

Money isn't an issue as I'm not looking to cheap out on the exhaust. What I don't want to do is fork out good money for something that looks nice while having nominal performance gain. I don't want to put Chinese crap on my bus either.

Thanks again

The Vintage Speed is made in Taiwan by a small VW shop. It's high quality, heavy and beautifully welded. FYI Taiwan and China made are very different things. Most of my best hand tools are made in Taiwan, they have one of the most advanced manufacturing economies in the world focusing on small and medium sized business, they are democratic, and have a highly educated and well-paid population. Worlds apart from China.

I have the single-exhaust one because I asked them, and they said it was little quieter than the dual-exhaust.

I don't think anybody has done side-by-side dyno testing but my impression is that the header style (which you have) is probably slightly more "powerful". The Vintage Speed will be more powerful than the stock, but maybe slightly less than the header type. We're not talking huge percentages, and much of the gains probably at RPM ranges rarely seen on a bus.

The Vintage Speed has a nice rumbly exhaust note. I've had several people ask me if I had an engine conversion, since it doesn't quite sound like a typical VW. It's louder than stock, but not IMHO overly loud. It will last a long time being stainless.

If you're looking for "the best", "price no object", then probably the Python header style is the best, no compromise on performance and no compromise on longevity. It will be pretty loud and the valve access is an issue but I've heard not that big of an issue. If you are running a stock engine I suspect however that the "performance gains" will be pretty minimal since there's just not that much gains to be had with the stock cam. If you are running a hotter cam, maybe bigger valves then letting it breath will open up the potential.

Forgot to mention that you can get a stainless empi to replace the one you have. I've actually heard pretty good things about it.

I'm leaning towards one of two Vintage Speed models. I liked the dual tip until I heard one on YouTube making a whistling sound that I didn't like. I also heard the single tip and it sounded really nice. Mind you the single tip had the equal length headers. Not sure if there's a difference between the two cans. Which of the two do you think looks better on a bus?

[richparker]

Twin tip

My experience is with the single tip "sport" not either of those. But I suspect you will find the "superflow" exhaust to be louder and that the hidden tailpipe location is not ideal. In a bus you want the bus to exhaust as close to the side as possible. Exhaust exiting to the rear will get sucked back into the bus at speed.

You may want to contact Tangerine racing and see if they have one of the exhaust set ups that Jake and them designed. If you don't run a hitch then this may be a very good solution for you. He may be willing to bend up another one.

I am running the new EMPI SS exhaust w/ 72-74 HE's and its really nice. Low rumble sound but not too loud inside going on the freeway. Definitely helps power wise with my CS engine. I got it for $229 not at Cip1.

Scroll down this page of Notchboys thread. You’ll find a video he took of driving his ‘77 uphill with the twin tip VS.

I'm at a fork in the road here. I didn't want a nice looking exhaust with nominal performance gain, but then there's the empi ss. I really don't want empi again but it seems to be the better option performance wise. Feels like a shotgun wedding.

I'm still liking the VS with the hidden tip look, but told the bus will suck up the exhaust. Maybe if I drive faster it'll be ok? Such a difficult decision. Trying to pull the trigger today to take advantage of a Halloween special. Thanks for any and all advice.

So is this stainless steel T-bird header copy offered by VW Heritage.....the same part as the EMPI ss header?
