Opinions?

I just took my car to Meineke with $150 in my wallet, my stock dual exhaust is missing a muffler so I have 2 new Apexi n1 style mufflers and two 1 1/2 foot exhaust pipes I wanted them to take off the stock muffler that was left and weld the new stuff on... The guy goes underneath my car, comes back and tells me it's going to be $300 because he isn't going to do a crap job and he wants to do it right and make and install a custom y pipe because without it everything wouldn't sit right and because the y pipe is rusted up and welding will blow through it supposedly, is he being normal or over charging me because I'm 18 and I might seem like I have $$ because of the way my car looks? P.s if anyone can recommend a place in long island NY that does this work I would appreciate it.
