I was just wondering how many of you guys have ever ran a glass pack on one of these NBS GenIII vortecs? Cause my friend has shortty headers an stock Y pipe into just a single chamber flowmaster. But he was thinking of changing out the Flow for a glass pack.
Do you think that will help the flow better than the single chamber?
An how do you think it will sound?

 

I think he should leave the Flowmaster on it. The glasspack will make it sound like ***. But thats just my opinion.

 

magnaflow is a good muff.

 

 

Another vote for Magnaflow.

 

I like the Magnaflow and the Flowmaster. They both make exellent mufflers.

 

does he want it louder or to flow better. glass packs will sound like *** and also be alot louder. if he wants more flow take the cats off, or hell don't have a muffler on it at all. the 1 chamber flows very well becasue it is a race muffler and about have the size as any other chambred mufflers. I would jsut leave it alone and focus on soemthing else becasue he isn't going to get any gains from switching mufflers. IMO

 

i have a spintech muffler, little costly, very good flow, sounds great, not annoying sound.

 

lol...sound like ***

 

Yea I thought it would sound stupid to. Another question now is, what kind of Magnaflow Muffler you guys running? Witch one sounds, flows the best?
