Exhaust Question

My friend has a 2001 Eclipse that he will be puttin gexhaust on. He wants to order all the stuff (Headers, High flow cat, muffler) online, but all the stuff he wants has diffrent inlet and outlet sizes. Would any muffler shop be able to have the adaptors (and weld them in) to make all these fit, or would it have to be a specialized shop?

Thanks

I thought the cat systems came with their own tips...unless if hes talking about getting another one for some reason

he would probably need to find the diameter of the headers, then find a high flow cat with a inlet the same size and then find cat-back piping to match the outlet of the high flow cat. if that doesnt work, then im sure that a muffler shop can help you out

Yeah hes getting a high flow cat (more hp), so that and the header would need to match but a shop could handle the cat to muffler diffrent piping sizes right?

yeah most shops could handle it.
