I am planning on getting a carsound hi flo cat for my 94 GSR. However, I went to there website and they didnt list any part numbers for different cars. I was wondering if anyone knew a site where they list the different part numbers or knew the part number for a carsound cat for a 94-99 GSR with stock intlet and outlet size. Also, where is a inexpensive place to but one. Any help would be appreciated, thanks.

 

You have two options with Carsound cats. First, you can buy a universal one and have a muffler shop weld on the appropriate flanges. Your other option is to purchase a custom-made one from somewhere like SMSP or IPS Racing. My suggestion would be to go with the custom-made one. Just tell Dave or Mike what you need, and he'll set you up with the proper cat.

 

what he said. They come without flanges and the option you have to concider is only the piping diameter. I've got one and I like it!
