I'll be ditching my home made rigged duals for a quiet catback and going to get a ypipe with electric cutouts. Shortest bullet Mufflers will be put behind the cutouts.
Car will be slightly louder than stock on cold start but crazy loud open headers v8 when I open the cutouts.
I have 2" Kooks with Burns Stainless 3.5" mufflers.. I want to v band the mufflers, and build a 3.5" x pipe, and v band the headers, and x pipe, that way I can move the mufflers around if I wanted.
Mines not a race setup at all. But I've been wanting to change things up for some time. I think we're running the same headers. 2" kooks with 3.5" collectors. I have the stainless kooks y pipe that bolt up to the headers. 3.5" inlets and a 4" outlet with a 4" cutout right past the merge. I've been tossing around the idea of doing a custom built 3.5" y-pipe with a 3.5"-4" fm merge and a 4" bullet muffler dumped. Anyone seen anything like this?
I also like this true dual setup to work with a chasis mounted torque arm.
Also wonder if it would be worth doing 3.5" duals at our power level?
Who makes that torque arm? Tons of clearance at the cross member compared to mine....
Here was my exhaust back when I was N/A. Had great clearance (But I am not lowered). It was a 3" Y-pipe that merges to a 4". 4" inlet Borla XR-1 muffler. Sounded great. Performed great. Done deal
NICE! You got a sound clip of that beast? I'd like to do something similar just to lose the 30 or so lbs with a catback system.
Not yet, still needs to be tuned. I will say this, I would never drive this on the street (it is LOUD but sounds like a nasty big block), it will be a track car. I did weigh the borla catback removed and it was 50# exactly! So yeah, dropped at least 35-40#s
All seems too complicated and heavy for a race car... How about a 4" dump with electric cutout. With a 2" kick out pipe. Nice and quiet cruising around town, and supports 8 second times at 160 at the strip when the dump open.
Added a tiny 2" cherry bomb muffler, but it didn't quiet it down as much as I thought it would.
Sup Bolo, haven't seen you in person for years, hope you are doing well. I'm still racing up at GLD with the 5th gen.
My experience, the Dynomax bullets knocked down a little of the volume compared to open headers. Still very loud. I try the Magnaflow mufflers round long and narrow and the sound was about the same.
Borla XR1, the small oval mufflers, did drop quite a bit more. I'm talking the model that is about a foot long.

Hey John, all is well my friend. My 416 is finally done. I will definitely be at GLD this Fall for sure!
I will look into Borla XR1's, Hopefully I will see you there.
Wow, the Borla XR1 are $179 each @Jegs and I need a pair.
I was also looking at Dynatech split flow race mufflers. Their about the same dimensions as the Borla XR1's, but sells only for $129 each. Of course, their made of aluminized steel vs stainless steel Borla's.

A single 4" bullet (Dynomax) is less than $50 @ Jegs.
