Just found out my muffler's too big, what to do?

I just found out that a muffler I bought a while back is 2.5" inlet, while the Solara's piping is only 2.25". Does this mean I need to put 2.5" piping all the way, or is there some sort of short piping that will expand from 2.25" to 2.5"? What should I do, and is it worth it to have 2.5" piping on a I4 all the way if I have to?

Three options depending on the shop you go to. Tip: Avoid shops who can not bend pipe, they have almost no skill and depend on clamp together parts.

1) If the shop can reduce pipe diameters. (Called OD sizing) the inlet can be sized down. Many shops don't have this capability because tooling is expensive.

2) If OE pipe is 2.25" Size the OE pipe up slightly. The shop would make a ring bushing from a piece of tubing that fits over the OE pipe and inside the new muffler inlet. They tack it together then weld the three layers with a wide bead.

3) Aftermarket bushings (adaptors) are commonly available. a 2.25 ID to 2.5 OD is very common.

Check with the muffler shop first. They know what they are doing and this is a common scenario for them. (Not a show stopper.)

Lol, thanks Phreakd. Can you believe I've waited this long to install the muffler, and then I'm going to sell the car and get a 6cyl. Might as well dust it off and install it now, or it's gonna be another month before this gets installed (and it will be on a 6cyl).

My HKS has a 2.5 inlet and they just made a custom pipe and screwed it on so i could just stick the stock back on if anything
