i like those alot. wish they had 32 16s. I cant find them. I have a 98 as well. Mean exhaust leak, my downpipe separated from the flange at the exhaust manifold. Check that out first. Dont do like I did and pull the driver manifold to find out it wasnt leaking. You go to a good muffler shop they can weld it back no problem, like 30 bucks. Hope this helps
