A Bit Pricey?
 

I'm still new to modding, so bare with me. I think these guys were trying to get over on me. 390 dollars for 2 Flowmaster mufflers plus installation? Man that's insane for 2 mufflers I think. Just the mufflers, no pipes, etc.

Is that a fair price? And what mods can I get done for around 200 bucks? Lol I'm dreaming...

peace

That's a serious ripoff. You could buy the complete Flowmaster catback with the pipes and have it installed for that much.
I had two Magnaflows installed at a local muffler shop (purchased the mufflers from them) and the total was $200 parts and labor.
I would call around to some other shops. Also, you can always order mufflers for cheaper than they sell them at the shops, so you may also want to ask about the price for installation only.
