Has anyone ever tried dynatech inserts?
I put LTs on with highflow magnaflow cats with my corsa sport and it sounds like crap. I know most guys are using some sort of bullet muffler but the insert seemed like a good idea if it actually works.

 

I tried using one in my exhaust before the muffler. I stuck it in where the cat back bolts together. It made absolutely no difference in sound installed that way. It might be different with 2 installed in the collectors, but not worth the cost compared to a bullet muffler IMO.

 

Yea I did a search about them on some other sites and most said it made a little difference but not as much as what i'm looking for. I guess I will have to bite the "bullet" and hack up the exhaust and put a second muffler in.

 

Are you talking about the pop bubbling sound you get with headers? Sometimes its smooth engine sound and at some rpms you get that bubbling pop sound?

 

I have two 3'' inserts in my turn downs
