I know this is an older thread, but I just picked up a 98 2.5L and immediately removed the snorkel and put two ovalized 9/16" holes in the internal muffler pipes as described here. So glad I did. The muffler modification is subtle, mainly deeper and louder right off idle. The snorkel removal is a must. 5000rpm and up is spine tingling now.

I will probably be doing the Pedro's/PSE partial muffler bypass in the near future to give a little more exhaust noise.
