I want to change the muffler on my stock 305 tpi, but the thing is I can't find anything that will be a direct replacement. I have dual exhaust, an in and an out offset on one side of the muffler and on the other side is just an out. I've looked on summit, on here, and through the search and I still can't find anything with an in and an out on one side of the muffler with another out on the other side (in meaning exhaust goes in, out meaning out obv i just dont know how else to word it so, sorry.) Could anyone give me a part number, a series, or anything to help me out? I want to get a Flowmaster because thats what I have on my 81 and they sound great. Thanks for the help.

 

almost every exhaust company makes a cat back system for third gens if you wont just the muffler most companys make a direct fit muffler jegs sells a flowmaster 80 series muffler

389-42583 2.5 in/out $72.99
389-43083 3 in/2.5 dual out $79.99

they also sell dynomax, and hooker direct fit mufflers

 

thanks, its kinda hard to tell on summit if it was dual outs on a side or in on one side and out on the other or what
