I’ve seen a few of these setups any members running something similar like this? Planning on swapping my current exhaust for this. I have the parts already on the way.
This is a decent set-up but is very expensive to fab it this way. I have true duals and eventually will convert back to a large single after the header collector merge. When that time comes, I will go with a Mufflex 4" and then tie it into a Y right after my cats.

I was thinking of going with the 4” set up. I did have the TSP 3” true duals car sounded good but was fighting clearance issues with the piping I went back to my mufflex exhaust set up but now it sounds raspy and not a fan. The engine is a lil different I’m running an LT5 from the 90’s v zr1 so the tone is different vs when I had the TPI and Ls in it

I mitigated fitment by making a million custom adjustments for my duel exhaust. The problem you get is with drone. It's maddening and makes me want to go back to a single setup .
I hear ya on that one. The exhaust I bought brand used so it was already modded but still rattled. Drone wise I didn’t have much of that it was more of the fitment for me. So that why I’m going to give it a shot with the setup in the pictures I posted and hopefully it sounds cleaner
the SLP exhaust on the second pic folks on the Ls1tech forum would call it like that. This was way before the true dual exhaust were even available. I think the only that had one at the time was the Bassani exhaust set up.
I've been away from the 4th gen world for a few years, but wasn't that setup with 2 dual tips (2 pipes sticking out on each side of the bumper, so a total of 4, dual exhaust with dual tips)?
Drone notwithstanding, I'd be interested in the difference in volume between two mufflers vs one. I can't see how a 4" muffler of sufficient capacity couldn't be anything but LOUD.
As for the dual dual (or whatever you want to call it), I look not only at the added complexity (as noted) but also the added weight. An additional muffler and tail pipe (plus those band clamps and merge ) have to weigh in at 20-30 lbs wouldn't you think? I suppose if you don't race it's of little concern but for those of us that do, reduced weight equals a quicker car.
This is similar in concept to exhaust I once had on a 1994 Corvette. It droned like hell at cruising speed. It was particularly bad in the passenger seat.
Experimentation is really the only way to know for sure what happens though because everybody's car is a bit different.
Funnily enough I like the Flowmaster "American Thunder" exhaust (circa 1998) I have now. Subjectively, it sounds great at any and all conditions. Crisp at idle. No drone at any RPM or condition. But objectively, it's a piece of crap given what I need an exhaust system to do. This is why I've been in on the threads about what's available for these cars.
