Road testing Nearly Complete For Dual Outlet Muffler

I've been putting miles on the latest version of my muffler here lately. The sound is slightly muted when compared to the stock outlet muffler due to half of the exhaust dumping on the passenger's side. The look is nicely balanced but I don't like how the stock valance is not symmetrical. The driver's side had some odd red light that I removed and the valance under it is formed to fit the mount. Looks like a good candidate for a fiberglass unit.

Anyway here is the prototype. I trimmed the tail pipes to match this evening but it was too dark for the pictures. The first production unit will arrive soon in full polish. Can't wait to show off that one!

The odd red light is Europe's version of a rear fog light. They actually do come in handy. When I had my old Audi, I had a BMW 740IL use this to follow me while driving home from the beach in a Hurricane/tropical storm. I stopped for gas after a couple hours and he followed me in to thank me. Neither of us realized there was a hurricane till we were in it, and our love one's had called to make sure we weren't driving. Thank goodness it wasn't the P-car cuz she doesn't see rain! Anyways, sorry for the story, I still get a kick out of it 4 years later....

Can't wait to see it all polished up! Lookin good!

I'll update my website soon with pictures and pricing. Should not be too much more than the single outlet version.
This one weighs in at a whopping 11 pounds!

A couple of things:

First- Hats off to you Rarly8 for your parts manufacturing endeavour- what a great job that must be.

Second- I think the exhaust pictured would look better if the tip protruded a bit farther out from the rear valance- just my opinion.

Wow..

+1 on both points exactly..!

Based on where the tips are now, its just a mtter of time before the exhaust darkens the bumper area above.

Again Brian.. nice work!

It is nice to do something you really enjoy and to also not be dependant on the income. There is no pressure to sell for the sake of selling.

The tip position was determined for aesthetics only. I wanted to tuck them in under the bumper for a smoother look. Running rich will leave a spot that needs to be washed off every time you wash the car so that it does not stain the paint.

How far must the tips stick out to not leave a residue on the bumper?
Would flush with the end of the bumper do it?

I love it like that, plus my car is black so won't see the residue!

Yeah I think flush with the end of the bumper would do it.

I like the look of the unit, very well balanced from center-left-to-right. Tips seem to have the look of the old DP mufflers, not quite round but not quite oval either.

Both this pipe, your single and the Zork are very nice alternatives to the stuff that's on the market these days. Qaulity appears as good or better and price point is waaaaay better!!

Thumbs up

Yeah, now THAT is the ticket !! It makes the car look a little more modern and up to date. Hopefully the sound is cool as well

Thanks for the complement. The tailpipe design focus was symmetry and ease of installation (read - stay out of the way so you can get your arm up there without removing the valance). The outlets are a little tricky to cut in order to get the angle and look just right. All of the residue collects on the bottom side of the bumper where it cannot be seen. Mine are black on both sides from heat cycle runs (that's my excuse for boosting and I'm sticking to it).

I do all I can to keep the cost down. Unfortunately the choice is USA production, feather wieght and strength (321) vs Chinese production and lower cost materials (aluminized). Being they are designed for a 930 I opt for the former.

Maxx - these mufflers are performance oriented. They are loud. Not Zork loud but much more than stock. Muscle car loud.

Loud is good. The only thing I have to measure by is my GHL exhaust which is throaty but not what I would consider loud. As long as I don't have to worry about driving past cops, it should be great!
