Latest Ideas for Minimizing Rasp
Thanks.
It has alot to do with what header you're running too. The Macs are pretty bad about drone and rasp.
I would love to. But I blew all my money on the Heads/Cam/LS6 Intake/Pushrods/ASP Pulley/160 stat. So for now, until I'll have to "band aid" the nuisance. Bullet in the I-Pipe will be next. Where can I get these mufflers? I hope they're not expensive. Oh, and to repeat the question, any HP loss? If so, I'm sure it's minimal, my ears need relief.

A true dual set-up also fixes that problem without the cats.Maybe some people have had luck with the Dynomax Bullet mufflers in their I, but the ones I've heard did hardly anything to get rid of the rasp through a cat-back system on a car running no cats...

Starting tomorrow, I will stand on the median and hold my bucket with a sign reading "Need Longtubes, God Bless."

Mike, the bullet muffler I used was an SLP (the absolute longest I could stuff between the collector of the Y and the cuttout.) It got rid of at least 90% of the rasp and certainly flowed better than any cat. I can't vouch for the Dynomax brand.

Colonel, I now know which route I'm going....thanks. Decreasing 90% rasp is like heaven right now.
