Gen1 exhaust wt comparison: OEM vs. Bassani vs. Supertrapp vs. F1

Hi all - here are wt comparisons for different exhaust options I have personally owned (attached .bmp file)
The F1 gives you a good wt reduction, and are still somewhat obtainable. The Supertrapps have the best construction and finish IMO, but a little harder to find. But nothing compares to the Bassani: best wt reduction, beautiful swirl of the pipes as they go from 4 to 1, and the sound is absolutrly awesome. The black matt finish scratches easily, if that matters to you.

Chart notes:
* OEM wt includes front header pipes, chamber, both mufflers, but not rear head pipes
** Bassani re-uses the 2 short header pipes that mount to the rear cylinders of the V4
*** SuperTrapp, F1 re-use all OEM header pipes and the chamber, i.e., “slip-ons”
All weights measured via multiple sampling using same bath scale. Variation ~ +/- 8 oz

 

nice comparison. i cant believe the whole stock exhaust together ways only 26 lbs. not too much room for weight savings there. on the sixth gen the just the stock mufflers alone are said to weigh 26lbs with the headers around another 15 or so...

 

jeepers, maybe the bath scale is way off, in which case the indicated 200 lbs for me could be more like 300! For reference, a US gallon of milk weighs 8.35 lbs.

 

I have a Supertrapp exhaust System that replaces the complete stock system less the two short header pipes on the rear cylinders. The front cylinders go off to the left side and rear to the right. Im just waiting to get two new mufflers before I put the exhaust system on the bike. I haven't heard of Bassain before. Where they from and are they still avalbile?

 

CandyRed - I no longer have the OEM system so I can't confirm the weight, but I'm pretty sure 26 lbs is correct for the pipes, chamber, and 2 cans (not including the wt of the 2 short pipes that come from the rear of the V)

TwoWheel - you remind me of a key point: the Supertrapp slip-ons are different than the Supertrapp cans that go on the full Supertrapp system 2 into 1 that you have: the slip-ons are longer, since the stock exhaust does not reach back as far as the Supertrapp header. I'll post a pic of what you need to be looking for seperately

about Bassani - they're still around (since 1969 per they're web site - Bassani.com) but seem to sell mostly Harley pipes for bikes. They also do mustangs, vetts, etc. On a wim, I called them last week about getting a part and got the expected reply "we don't carry parts for that old stuff"

 

pic of a single Supertrapp can for the Supertrapp 2 into 1 system. NOTE: this is not the same as the can I weighed in the chart; that's the slip-on

 

Attached here is a pic of the Supertrapp system I weighed. Note that the stainless cans have the mount bracket vs. the cans for the full system.
BTW, I'm skipping the Preview step in these posts, so you'll learn new ways to mis-spell and mis-use words here: they're vs their, wim vs. whim, etc

 

The strange or odd thing about the full system is that the rear header pipes go back farther then the front pipes so when the cans are installed the right side is almost passed the rear of the tire!! I'm guessing that this was to try to balance the system.

 

I have this old pic of a Supertrapp system on a 1000R. I always thought this was strange; you mean this is "normal"?

 

Avoid the F1s as they are cheaply made, tinny, raspy, buzzy, bad- sounding units nowhere near the quality of better systems that bring out the mellow rumble and deep bass sound the VF produces and have problems with breaking welds.

It seems that the F1s are tuned (or just slapped together) to sound best on inline 4s and don't translate the powerpulses of a V4 anywhere near as well as a Micron or Hindle.

They are very light, however.

 

TwoWheel - a pic per your comment on SuperTrapp full system length on the right side...(this isn't my bike). Need rear bumper?

 

BTW, if you have on of these systems off your bike and would like measure consistent with my method, I'll update the chart. These are the other pipes I know exist for Gen#1 (got pics):

Cowley full system 4:1
Hindle full sytem 4:1
SuperTrapp full system 4:2
Vance and Hines full system 4:2
Targa by Kerker slip-ons (seen in red or blue)
Yoshimura make one?

 

I just installed an old...well used pair of F1's on my bike and I'm surprised how much lighter they are compared to the stock OEM cans.

The F1's sound better then stock IMO.

 

F1's are ok, but I kind of agree with S-man that they are little junky. Maybe it's just my tastes. They seem to hold up pretty decently though, so maybe it's just a preception thing. Being aluminum is nice because you can scotch-brite them or polish them up to keep the appearance looking good. The sound is ok, but only on the F1r versions. The standard F1's are too quiet for my tastes.

 

What is the difference between the F1 and the F1R's?

Cause my F1's are LOUD!! :smile:

 

The F1's have a standard baffle, meaning if you took one off you could not see all the way through it. The F1r's have a straight-through baffle design, sort of like and old-school glasspack. I've found the F1r's to still be pretty quiet.

 

Zoo Zoommmm

So, Where the heck can you get a full exhaust 4 into 1 system, Iv looked and I cannot See any that are still on the market .If anyone has one pm me nd we can Camel trade lol..:thumbsup:

 

You haven't been able to buy one of those for about 8 years now. Sorry!

 

I'm having a full stainless 2-2 system made right now; I'm having a company in Michigan replicate a Vance & Hines header set that I sent them. It's going to be pricey due to the tight bends, which means extra labor on their part. (some of the bends are 2 & 3" CLR)

I will have solid pricing by tomorrow.

 

bringing the old school back to life ... thats awesome! i think itll look great with a modern muffler. like maybe a carbon 2bros:thumbsup:
