Has anyone really noticed a temperture decrease utilizing this muffler? Are you using the 4040, or the 4040L? Does the 4040L cut the "raspy" edge off the straight pipe? Is it worth the investment?

Might make your exhaust sound cool but it ain't going to do jack with your EGTs

 

I run a T5050L on my Dodge. It took a great amount of rasp out of the 5" straight pipe setup.
Made it street legal... no more loud exhaust tickets.
I noticed a slight egt decrease.
It sounds awesome with the stacks.
