Aluminum under the heat of exhaust temperatures gets VERY soft. It is unfortunately not a reliable solution for lightweight exhaust parts.
The exhaust scavenging effect you're referring to better applies to a naturally aspirated car where the exhaust system itself is responsible for being tuned for length, bends, diameter to pull exhaust from the head. In a turbocharged application it is the manifold responsible for scavenging the exhaust and making its transition into the turbocharger for maximum response. The exhaust outlet from a turbocharger is most functional when there is literally zero restriction, thus the reason most turbocharged racecars usually have the shortest possible straight pipe exhaust "system" to evacuate exhaust gasses from the engine bay.
I wouldn't worry about the resonators so much if it didn't weigh so much that it stretched your exhaust hangers. Talk about GETTIN' LOW

We do have two versions of our 3", 3.5" and 4" exhaust systems. One is for the standard USDM bumpers and the other for the JDM rear
Just specify when you order, it's no additional cost either way!I dont believe they sell staged kits but you could buy this exhaust along with there intake, a hallman mbc,walbro 255 fuel pump and get a mail in Jestr tune for a stage 1. Intercooler and piping for a stage 2.Pm ETS Tom for the hookup and great customer service.I spent alot of time looking at vendors before purchasing and went with ets.
Thanks Carlos! If there's ever anything I can help with, be sure to get a hold of me
We also offer both 3" and 4" systems for smaller and BIGGER power needs!Tom

For all of the JDM rear systems we've sold I honestly don't think I've ever taken a picture here or gotten a picture back from any of our customers. So to those running our exhaust with a JDM rear, I'll trade some in-store credit for a good picture or two
