Yes they are 2 electric cutouts, I had to point them in the same direction because of my subframe connectors the driverside one wouldn't fit facing outwards.

I put them on there because i was unsure of the sound from the duals, i never even cracked them open so when the duals went so did the cutouts.

Nothing "bangs"... its supported very solidly by the hangers near the turndowns. And, those are not LT headers.... they are AS&M's that heve been modified so they can be run as duals.

The Spohn TA is solid as a rock. I'd like to have a new front mount made, maybe a little lighter. The one on the car now is for the 4" Mufflex catback, which has obviously been replaced.

Those are Borla 3" XR-1 straight mufflers, 12" long.

The system was originally 3" Carsound cats bolted to the collector flanges, a custom Mufflex 3" Y-pipe, a Mufflex 4" catback. I had the Borlas made up to match the cats, so when I went to the track and ran leaded fuel, I could swap the cats out with the Borlas. When I added the Gear Vendor to the TH400, the Y-pipe wouldn't fit any more, so I removed the Mufflex catback (saved 50#) and went to the current design. Mufflex bent and installed the 3" pipes for me. I live about 20 minutes from Mufflex.

The Summit kit didn't work for me. I had the exhaust shop fabricate everything.

Any drone in the inside with the exhaust setup that way? In your opinion which sounded better the mufflex catback or the borla duals?

My Kit was a summit 3'' universal kit. The front legs had to be trimmed but other then that the exhaust guy said that was the best fitting Store bought kit he had seen for any car running duals.

Its pretty loud inside the car. But its mostly a "track" setup. The Mufflex was very quiet in comparison, until you put the pedal to the floor, and than it would come alive. But it also had a resonance at about 2,500rpm that would cause my chest to throb.

The worst trip I ever had in the car was driving it about 75 miles from the shop in PA where they had just installed the Gear Vendor, and couldn't put the Y-pipe back in. I drove it all the way home with just the Borlas, no pipes at all, and everything inside the car and inside my head was rattling for an hour-and-a-half. It looked like this.....

Thanks for your opinion. I think im going to spend the winter fabbing up 3'' duals over the axle, so i don't have to worry about drone or resonance.
