Best 4-1 Exhaust ?

[Guest]

I am thinking of replacing my exhaust system (4-1) for my 82 Gs1100E and was wondering which system gives the best performance and sound for the price.
I can only find a few systems out there. OK guys whats your opinion.

Vance and Hines is the defacto standard these days. Nicer quality than Mac at a similar price. Are there any other brands even available anymore?

Vance & Hines & Mac are all I've been able to find. Supertrapp/Kerker doesn't have them anymore. Here's a link, not a bad price.

Sound is a big factor for me. I dont want to be grouped into that Loud Motorcycle gang.

My neighbor has a chopper with shotgun pipes and he can wake the dead with that noise. Well maybe not the dead but for sure a napping grandaughter. Ask my wife. "If that F'er wakes her up with that GD MC Im gonna be pi**ed !!"

I see you have some nice performance upgrades on your bike so a little louder pipe probably does not concern you. Do you still have the orig pipes ?

Yes the bike shops in my area most certainly do suck, but I can't find any of those either??

Bassani & Jardine I've seen used on ebay but they don't list them in their catalogs (only harley). I called Jardine and they do not make their exhaust for the GS any more. I have not called Bassani.

Advantage racing in Japan makes a stainless pipe of which there were a couple on ebay, but they're only for the 16v bikes.

Back in 1982 Cycle Guide Magazine published an article were they dyno tested all of the early 1980's 4 into 1 pipes on your GS1100E. The Cycle Guide testers evaluated pipes from Kerker, Jardine, V&H, Bassani, Supertrapp, Yoshimura, MAC, RC etc to name a few. The article also looked at centerstand & oil filter retention.

The dyno tests were performed on a stock 1982 GS1100E and were strictly limited to replacing the stock exhaust system with the aftermarket 4 into 1 (No Jetting changes using stock airbox). There was only one manufacturer which made more HP than the stock Suzuki GS1100E and that was the Supertrapp 4 into 1, which I believe from your pictures you already have installed. This is not to infer that hanging the Bassani, Kerker KR or Yosh pipe on your bike and uncorking the baffle will yield different HP readings. Doing so will of course make it much louder which is either a positive or negative based on you personal preference.

I cannot find the article on line but perhaps if you contact Paul Dean @ Cycle World (He has a strong afinity for the GS1100E, See Cycle World Feb 2008 he can dig up the article since he was working for Cycle Guide back at the time.

What's wrong with that nice looking Supertrapp that's on it now?

I bought a chrome and a black Jardine for my 1000's. I haven't installed either yet, but some say the Jardine out-performs the V&H. I think the Jardines are all gone, so your only choice that I know of is V&H. They sound good, but I think the quality has gone down some over the years. Mine was difficult to install and the chrome I think is pretty thin. My bike is tuned perfect, and the pipes still want to turn gold and blue. I plan on ceramic coating the insides of the Jardine pipes before I install them.

Here's some noise from the V&H:

In my opinion the best pipe you can put on any Jap 4 is a Marving 4-1. Looks minimalist and 'aggressive' and the sound is to die for. Captures that turn of the 70s / 80s spirit spot on. I've got one on my CB1100F and will finish off my GS1000 rebuild with one. Marvings are made in Italy; we can get them in the UK from exactrep.com. Not the cheapest and could be very costly in the US with the weak $ at the moment.

Got a pic? I've never heard of a Marving. How much are they?

Too much

Looks like Motad do one too... http://www.bandcexpress.co.uk/cgi-bi...TAD&nav=Suzuki

Isn't Motad the UK equivalent of MAC?

The reason I was thinking of replacing the SuperTrap exhaust was because the Chrome Plating was scratched and discolored along with some scraps from dragging in the corners.
After reading your replies at lunch I called the only local Electro-Plating company. The man that owns the place is a fan of the older bikes and told me he could take out most all the scraps, scratches and re-plate the back half of the exhaust for under $100.00. The headers are fine, after I removed the bluing last summer they have taken on a nice golden look near the exhaust ports.
This is just what the system needs. I want to thank everyone for there input.

What was the value of this "test"? Pretty obviously, the stock bike would perform poorly with a free-flowing aftermarket exhaust system, without the appropriate jetting changes. The real test, IMHO, would have been to compare all of the systems performing at the optimum A/F ratio. The Supertrapp performed the best under the magazine's conditions, perhaps due to the extra flexibility it allowed with tuning the level of restriction in the canister. Lest we forget, the stock system also weighs a good 30 lbs more than the typical 4x1, so even if hp were equal, the modded bike would still have the advantage, so to speak.

Excellent points and my thoughts exactly!!
WOW, I never knew the 4 into 1's were 30 pounds lighter!!
That means my Katana will have dropped from 232kg to approx 217kg!! Thats lighter than most early nineties 1100's
