Need help,Exhaust and Sunroof problems Options

[97toyotacelicagt]

Hey guys I haven't been on here in awhile,but i've been having issues with my car,awhile ago I was talked into putting an exhaust on my car.They removed A cat. and just added 2.25 inch pipe and a muffler I bought on ebay which makes my car sound like hell. My question is how can I resolve this problem? I cant just buy my stock muffler can I? Since it wont fit the pipeing.

Another issue is my sunroof,it will not close,it can only open. I looked for a manual crank but could not find any tool to close it.

I want to make my Celica an enjoyable experience again! thanks guys

Well Im not sure about all the years, engines and emissions standards, but I have a 94 GT and the catalytic converter is a canister that fits inside the exhaust manifold and downpipe on mine, which leads me to believe that your shop removed the resonator.
The resonator is kind of like a premuffler, its just a hollow section of pipe/chamber that is wider than the rest of the exhaust, usually they look like a catalytic converter or glasspack but they are half way down the exhaust. The purpose of it is to allow certain frequencys to reverberate and drown out, most specifically the annoying pitches of the engine. It can also serve to amplify certain frequencys that are quite pleasant to the ears.

They can be had for significantly less than the muffler. I would get under your celica and see if you can find this muffler/cat looking piece, somewhere between the front axles and the rear wheels

It does help to tell us what model and emission standard (Califorinia or Federal) your car might be.

As Edy described, a resonator is a key piece in the exhaust system for making the exhaust note pleasant to hear. It also has the benefit of having minimal effect on exhaust flow, so in terms of performance there's basically no penalty.

Generally, its a round, smooth-bodied piece attached directly after the flex pipe. You can identify it by tapping on it -- a resonator is an echo chamber, and will ring like a bell.

A catalytic converter is typically ridged on the bottom to give it greater protection from any road debris, and will sound solid when tapped. On the 5SFE under federal emission standards the catalytic converter is connected directly to the bottom of the manifold, in the engine bay. Only California-spec GTs came with a second catalytic converter; it took the place of the resonator, which was moved farther to the rear.
