A few folks wanted to see a side shot of the tailpipe to see how it looks from that angle. Here ya go:

I've got a 934 W/G pipe coming next week that I plan to modify to have the same adjustability as the center outlet muffler; both will be capable of use with or without a valance. That is the design you will want to perfectly fit your Kremer.

If you like I can mod the 934 pipe and send the hardware kit to Ben. He will manufacture the muffler components and package it up for you. I'm sure you wouldn't have too difficult a time convincing him to deliver them for you.
Shoot me an e-mail at Brian@RarlyL8.com and we'll work it out.


Love the Kremer by the way. My favorite sense the 80's. Those relocated rear tail lights create an awesome look!
Thanks for appreciated comments on the Kremer. Ben called to say he had been in touch with you on this project for your new design features, so all will be well. Thanks for your neat ideas to further improve this area of my favorite cars.

I am modding a 934 pipe this weekend for Jay. The adjustments on that unit will work for your Kremer as well and should take care of about any valance configuration.
I'll post the results when complete and get a few critical dimensions from you to verify.

Nice looking muffler, I wish I could hear it online! For practical purposes can you do a slope/driveway test to see if there are any clearance or scraping issues?

I am using one of Brian's straight Zorks (longer & straighter) on my sloped driveway with no issues!

btw: My driveway is sloped a bit more than the usual.

The grade would have to be very severe for this tailpipe to drag. It tucks up directly under the license plate and does not hang down much past the stock valance. My plate actually hangs down below the bumper. If I moved the plate up the tailpipe could move up another 1/2" or so.

Here is a comparison with the stock Zork :

You do good work.
I know you don't agree, but it would be nice to hear a sound bit posted, even if you have distortion to just give an idea on the noise level and pitch.
How long to expect the muffler to last from corrosion......it is 321, but will it last 10 years or more like the SSI have been known to.
Thanks

321 is a material that is superior to 304 it has been used for years in the avaition world in aircraft that don't get replacement mufflers for 20+ years

Fred, I don't want the muted sound of YouTube to misrepresent the product. What I will likely end up doing is using the POS digicam I have and just post a caveate that the sound is actually more loud in person.

As for the 321, the mufflers will likely outlast some of the cars they are on.

For turbo motors (like the TSIO 520), the 321 stainless pipes have to be inspected every year for cracks and holes. Pipes on our RAM C414 are replaced nearly every three years because of the same issues we deal with - high temps under pressure creating cracks. Under cruise conditions today (75% power), we ran 1520 degrees EGT. Our motors are 7.0:1 CR, 8.5L, twin plugged, 25 degrees timing, 20lbs boost, custom cams, CIS, air-cooled, 345 hp at 2700 rpm.

Just an idea, so people can get a true idea of the sound level, is have someone kneel down beside the pipe and start talking. that will give a good idea of the sound level (only at idle of course)

I believe it was Fabspeed that had regular video footage of a slant 930 running up and down the road w/ their setups. yeah it wasn't great quality, but it definitely got me excited..

P.S. I have a special piggy bank dedicated for a RarelyL8 system. Just got to take care of some business ventures before it really starts filling up.

Contrast is a good idea.

Honestly, I though someone would have posted a sound clip by now. My mufflers are scattered all over the world and only one has come back because the owner didn't like the sound - and it was a totally custom experiment.

I'm going to try and get something recorded but will need some help with it. I know NOTHING about digi movies and how to put them on the web.
