Exhaust Questions???
"Vette" magazine wrote an article about the Magnaflow exhaust gains on a 99 C5. My question is: Is the exhaust the same on the 2003 C5 as the 99. Furtermore, is the H pipe on the newer C5s better or the same as the older cars. Thanks in advance for any help.

I think the only difference in the exhaust is that the 1999 also had "pre-cats" in addition to the cats and I don't think the 2003's hav ethe pre-cats. The H-pipe is essentially the same as far as I know.
Keep in mind that some of there gains in the article can possibly be attributed to normal wear on the exhaust system. In other words, changing out a 4 year-old exhaust system (1999) should show slightly better improvements than changing out a practically brand-new system.
I changed my 2003 coupe to Stinger's and a Magnaflow X-pipe and love the change. Not sure how much, it helped the H.P.(made several mods at the same time) but it certainly did improve the sound enough to make it worthwhile.
Good luck. :seeya

Please correct me if I'm wrong, but I believe that before 2001 there were no pre-cats. Beginning with the 2001 model year, pre-cats were added.
Thus, when comparing changes in the HP, torque and sound related to different aftermarket exhaust systems, the model year would have to be considered.
