Allright the mission for my homemade/custom exhuast starts tommorow morning....ok for a 18 inch 2 1/2(inner diameter) piping its 4.95 at a local advace auto part store i figure ill need about 3 of them for the middle straight piece( no cat...Should i keep my resonator on??????) then a few 45 degree curves should do they run about 3 bucks a piece but theyre not mandrel bent :thumbdown but ill live with it. I really dont have money right now for a nice after market muffler

HOw would the bigger piping do with the stock muffler? Or hell should i just not run a muffler

?
One more thing how loud would my car be with the 2.5 exhuast with no cat and no muffler and maybe no resonator

ive only got 40 bucks i can spend till i get paid next week...What are your guys opinons/comments?
note:All i got is a cai.
