when i bought my teg it had a axel back and an intake and i have no idea wat kind of muffler it is but it has a little plaque thingy on the tip that says pro1 and has some chinnese letters.just wanting to see if anyone has heard of them and if there any good...

 

i think they're made by top speed...don't know about the quality of them though...

 

I have one of these axle backs on my car too. It lasted good for about a year, but now it is starting to get really loud and it is turning a gold color.
