Exhaust Piping Question!!

[bdt115]

Okay, Im soon going to cut off my stock muffler and put on glasspacks. The glasspacks have a 2 1/2" inlet but the stock piping is 2 1/4". I need to know how to make that fit. What size adapter should i buy?...i need inlet and outlet sizes on the adapter.

You can run a 24" glasspack with an 18" body.

What you will need is a y-pipe from the catalytic to the muffler, then a 2.5" mid-pipe will fit after the muffler.

My "home made" or "self engineered" catback exhaust system started off with cutting off and removing everything from the 3 bolt flange that meets the catalytic converters. A Magnaflow Y-Pipe (part no 10758) was welded onto the mounting plate. The y-pipe is a dual 2.25" inlet to a single 2.5" outlet. This was followed by a Holley Flowtech Red Hots Glass Pack Muffler (PART #: 50252FLT). The exhaust exits through a 2.5" Walker Exhaust 46909 Dynomax Intermediate Pipe.
