I would like to pass on how satisfied I am with Imco glasspack muflurs. I have an 04 Sunfire with dual tips and had both replaced with imco glasspacks.They have w I was worried that the sound would be too loud. To my amazement it sounds more like a V-8. Ith has a really deep sound. There is a noticable horse power gains as well.
Please take my advice and try the. You will not dissapointed.
PLUS I HAD BOTH INSTSLLED FOR $100 PARTS AND LABOR.

Did you just change the mufflers or is it a cat back?


New sig in the works

Aren't those made for diesel (pick-up trucks) engines?
