Are there any good performance mufflers for my '99 Seville that will give it more power without making it sound like a '77 GMC pickup or a Honda with one of those huge trash can mufflers?

Also what kind of HP gain do you think it will give?

Hello mnymaker,

You might want to look a Corsa performance mufflers for a bolt on application, but its expensive.

I have Borlas on my Allante, and I worked with a local muffler shop to install them. Keep the Cat and use a resonator after the Cat to reduce the sound somwhat. I'm sure others will chime in as to what they have. You may want to do a search as this has been discussed some already.

ttt again......Does anyone know if the 99+ Corsa systems can be modified to fit a 95 car without too much hacking/bending/cutting?

If this can't work out, are just the Corsa mufflers available?
