i used to have a shop that was performance minded, they would do what ever you wanted to do, no questions asked. and they were fair with you price wise. now closed, bummer.
the 2 shops i went to, i asked if they could slap a glass pack in there instead of the replacement res, both told me we dont have anything like that here...i was like really? and left. i did buy the flange from one of them shops tho, so im thinking they just want to rape my wallet. and thats the only place i could find the flange, or the net, (pep boys and auto zone just dont carry flanges) but i'd rather have it in had to make sure it fits right.
oh i bought the gasket first for a stock res to cat, took that to the muffler shop and matched it up to the flanges they had, 2.5 inside diameter.
but if you let a shop take care of it all they should have everything in stock, maybe bring them the glass pack if they dont carry them.
shop around, and then shop around some more.
oh and none of that patch your muffler stuff works for any length of time, i did it to mine, and it lasted like 2 days, or till you jump on it, then is all loud again. waste of time and money in the long run.
