Anyone know what dual exhaust gives the deepest pitched "growl" that is fairly loud?

Thanx for any help given

 

I don't know much but I know a guy who has Invidia on and that thing sounds mean. Deeeeeeeeeep growl.

 

The invidia has been my first choice for awhile but i was hoping to get a few more options just in case

 

HKS with a test pipe definitely has a nice growl with a decent loudness to it. It is by no means deafining, but you will be heard if that is what you are looking for.

 

What kind of test pipe on the HKS?

 

My dual oval Spugen has a nice low tone to it thanks to the oval Magnaflow mufflers. It doesn't have any of the harsh tones that the Invidia does. Testpipes won't sound any different brand to brand unless you get a resonated model such as the Megan.
