Fabspeed dual outs DIY #2

M491driver · 07-01-2006, 08:08 PM

Just finished my second DIY project on my car. To celebrate it's first anniversary in my garage I added a second outlet to my Fabspeed muffler. To make it easy to go back to stock, I bought a second rear valence from a fellow pelican and cut it with the second outlet hole and stored the original. Since its an original M491 thought it might be wise to do this if I ever sell it. The project went without a hitch. I cut the valence with a jig saw. Most of the time was spent trying adjust the outlets to look balanced for angle and height. It looked OK eyeballing it but looking at the pictures I see some more adjustments may be necessary.

It sounds great. Just the deep rumble I was looking for.

Nice work. FabSpeed makes some pretty nice looking mufflers

Looks great Jim! I'm sure it sounds better! So how does it feel?

I still can't believe we haven't seen each other yet - it's not like Simpsonville is a big town. Heck, and we live off of the same road just a few miles away from each other.

Later,

How did you go about adding the second outlet to what I presume was built as a single outlet? I have thought about doing this to my single out GHL. Did you get the matching tip from Fabspeed?

I have a Fabspeed dual that is capped, with the second tip in a box. How much louder is it, and is there any perf difference you can feel? My car's a cab, and if it gets too much louder, I will keep it in the box!

We need to fix that. PM me, I would like to do a drive by one evening this week. Summer school is over and my time is much more flexible now.
BTW it feels like a muscle car!

The muffler had a second tip outlet capped off so after I cut the valence open I popped off the the cap and added a fabspeed muffler tip.

To me its muscle car loud which is what I wanted since I come from a big block corvette background. If I get tired of it I'll cap the second outlet and put the original valence back on it. I love the deep throaty growl which I think is the perfect match for a widebody carrera. My wife says it shakes the dishes in the kitchen when I start it up. Did I say I love the sound?

I'm going out of town on business this week, so it may not be such a good time for me. However, I'll PM you when I get back. I can't wait to hear the dual outs! Won't be bad to meet you either...

Later,
