Muffler-Exhaust for 1600cc Stock

I was informed by Jake that I should SERIOUSLY consider tossing the stock muffler, they are terrible for heat retention and economy. Any advise on what would be a good replacement?

Let me know
Thx

I too am looking for a replacment muffler-exhaust.

I have a "duel quite pack" installed now .... which I don't like the look of....

And I have a 2100cc motor

And suggestions for a replacement???

I'm very happy with my S&S rig... it can be single or dual style exhaust, tuned length for good extraction and oh yeah, sound good too.

I saw a very cool muffler in JC Whitney catalog. It was with the monza exhaust. It looks like the original with a round 36 HP look canister. It has two chrome tips, not four like the monza. I wouldn't expect as high a performance as an extractor balanced exhaust, but it looks very cool. The picture does not show the cool one.

Exhaust choices are dicatated by engine displacement, exhaust valve size, state of tune, whether or not you want to use stock or modified VW heater boxes, whether or not carburetor heat will be required (depends on climate - usually single carb setups, but also for some duals), and whether or not your engine will retain the cold-start thermostat and flaps (which is almost a given for a street engine for fast warm ups in cool weather, etc.).

Then comes the subjective stuff, e.g., looks and sound. The dual "quiet pack" systems are usually somewhat restrictive for anything but a stock 1,600cc (or smaller) engine, as are the "Monza" types and their derivatives.

I hate to tell Paul this, but if a system is designed to work as either single or dual outlet, it won't be a "tuned" system (regardless of what the manufacturer may tell you). If you want to know about tuned exhausts excellent books are available on the subject.

All of the above are why I had a custom 1 5/8" merged system built (with 1 5/8" heater boxes) that will clear the thermostat and all other stock VW engine attachments (note that some aftermarket merged exhaust systems will not clear the thermostat, so ask before you buy).

Slap me upside the head & dip me in shit!
My understanding is the tuned stuff comes down to the merge point where the muffler/tailpipe assembly bolts on...at this juncture you can slap on one or two mufflerzzz.

Maybe this is not bigtime tuned exhaust, but it certainly is less restrictive than the Monza style the car came with and judging by the RPM range improvement, something is sucking satisfactorily!


Guess you can't believe everything you read?

I must agree with Paul. I understand there is a possibility to tune an exhaust to a particular engine using many hours of dyno testing and fabrication. But, I believe a tuned exhaust in most cases means an exhaust where all pipes leaving the head are of equal length and diameter until they are merged. One or two mufflers (as long as the two are the same restriction)should not change the balance.

I also think that the question was what exhaust would be good for a 1600cc stocker. Let's keep it reasonable and not brag about how deep our pockets can get.

No offense George, but ...

Not bragging, just telling it like it is and what I used for a performance 2,110. He didn't say he had a stock motor, and someone else asked about a 2 liter engine in the thread.

Money has nothing to do with it - there are some good systems out there for a reasonable price (like KYMCO).

All,

Thanks... You are right, I did not state what motor I have. It is a stock 1600cc from 71 Beetle. I am using all new but stock parts. Jake suggested that the stock muffler/exhaust needs to be replaced, and I was hoping a suggestion on a stock engine that would improve performance.

Sorry for the confusion.. Any specific ideas or models or brands would be much appreciated.

Thx

If you want to read a very good article on exhaust systems for stock motors go to www.greatride.com. This is the site for VW Trends. A while back they published an article comparing 5 or 6 exhaust systems. Very informative. When you get to the site go to 'technical' and then go to the second page. The nice thing about VW Trends is that you can download past articles, unlike Hot VWs. Hope this helps.

Good article, Ron (I beleive it adresses the original question concerning the best exhaust for a 1600 cc motor). Here is the complete address for the article: www.vwtrendsweb.com/tech/0109vwt_bolton02/

Again, my understanding is there ain't much difference in the hook 'em ups from a 1600 to a 1776.No need for big blow dimensions,like 15/8", etc...That's why I liked my little S&S bolt on unit. No rocket science and no deep pocket required!

What the heck, put a tuned header on it, retain the stock heater boxes and put a open short stinger on it. Lots of sound, decent 1600 performance and it gives you something to explain to the Gestapo when they stop you. If you do the shortie stinger right it will look like a Boxer exhaust

They make stinger baffles too

has any one used a 'supertrapp' back of a merged exhaust? It is short enough to not stick out too far and can be tuned to engine exhaust needs, keeping sound down while minimizing back pressure. then opened up for road trips.

How short is the supertrap? I need one about 12 inches.

check www.summitracing.com they have 3 full ST muffler styles in their catalog, all the accessories and disc only adapter kits to custom build. The SuperTrapp S/C #SUP-443-2010 is 10" long, 4" in diam with a 2"inlet.

I run a longer supertrap on my silver speedster. It has the merged, 4 into 1 exhaust then an S that takes the exhaust back under the car, and out the back right side. I bet there is a picture in the files under Sweet CMC-C.

Why a Supertrap? Most of the VW go-fast guys run Dynomax, Magnaflow, Flowmaster, or A-1 Tiger "Fat Boy".

Dont know if the fixed units would be significantly different than the variable one. But to tinker with the supertrapp to add or remove pieces, changing the sound and back pressure, having the ability to match it to the specific engine is all attractive. 4 into 1 merged exhaust is agreed a better extraction than stock regardless of the eng size. After that..., letting the exhaust go quickly, resonably quietly, and with style.

Not to exhaust the subject (har har) but is the carrera exhaust the system that cylinders 1&4 merge to a muffler, 3&2 cyl merge to another, then both muffs merge to a single centered exhaust pipe? And/or anyone have info on that system. I remember seeing it last spring on an Euro site but cannot find it now.

Installation Problem:

In installed the new DYNO-TUNED DUAL-HEADER EXHAUST from JC Whitney at
www.jcwhitney.com/productnoitem.jhtml?CATID=63150&BQ=jcw2

Glass-packed detachable mufflers
Custom fit for '66-73 Volkswagen Type I Beetle, Super Beetle and Karmann Ghia
This specially designed system is dyno-tuned to scavenge gases from alternating cylinders and route them through the original body panel openings into two fully chromed mufflers. 18-gauge tube is mandrel-bent and wrinkle free. Dyno-tuned and equal-length design for high performance.

Here is my problem. When I try to put on the Glass-packed detachable mufflers they hit the body of the car and do not fit under the body in both the rear and the side. Looks like this system does not fit.

Ideas?

Thx
