Default Looking for a 4” inlet/offset straight through muffler

Looking at a 4” catback and wanted to see if there are any known 4” muffers with offset inlet/outlet with a perf core straight through design and preferably oval case. I’ve use the aero chamber muffler before as well as round dynomax ultra flow on another 4” that I ran and got ride of with a supercharger. Now that I’m turbo I’m looking to go back. I like the offset inlet/outlet oval shape for packaging reasons and they tend to be quieter than straight through.

this is a 5.3 ported heads, custom cam and billet 78/75 pushing 13psi+ daily. Currently it’s got a cutout and a full 3” catback but I miss the turbo spool with the full exhaust.

Looking for 18-20” overall length and a 14-15” case length.

Currently on the 4” list is:
aero chamber
vibrant street power

But I believe both of those are chambered and not straight through.

Yea I was trying to stay away from chambered bc of flow issues in boosted applications. Goal here is flow first and then sound in a close second.

I like the straight through magnaflow. Its not offset, but is compact. The turbo quiets it down compared to na, the magnaflows just sound good.
