Its not a stock quiet solution but more of a mellow drone less solution. But your using a 5" muffler as where the "quieter" claims have been made with a 6" center muffler. Also cams would add up on the sound as well if you have them.


Instead of going back and forward selling your exhaust I say keep it and try things one at a time. It will be the cheaper method.

Its hard to tell how quiet you want it to be. It seems like you just want it live-able but not stock quiet? If you dont have cams then I say get the vt muffler in the rear and sound exactly like stock normal driving and agressive tone at WOT . If you have cams but your idle is smooth then you can risk gambling with the vt muffler. Few had good results with smooth idles, but with lopey idle then forget about it.

Other than that you could try a section at a time. First put a center muffler with your current Bullet rear. If thats not enough then add the magnaflow rear.

 

my car came with this RSR turbo back exhaust setup lol and it was so loud....... like almost rotary loud. I wanted to sell the car the minute i went WOT lol. So I know how you feel.. when we start to get older we want something alittle less aggressive, starts to get annoying. the cobb i got is great, but WOT still is extremely loud. I dont think you;ll find something that you wont hear a block away with a big setup.

Rocks invidia sounds kinda similar to my cobb, i dont know how restrictive either of our setups are though.

Thats just a random youtube video btw, not mine.
