I'm running dual 2.5" side pipes with glass packs on my Cutlass and like the sound as it is a nice rumble but not like running open header. I want to get my ice racing chevette to sound like it has a mean V6 or V8 in between the front fenders but don't care to run mufflers or cats on it. What can i do or what size pipes can i use? Has anybody tried anything before? I'm open for all suggestions as long as they don't involve to much bending, shaping or flaring. If any one can give me some good suggestions but don't want to post them e-mail me at [email protected]
