I have a 99 firebird, only mod is pacesetter headers. I am wanting to change the muffler for one that sounds better and would give me a bit more power. The exhust on it is the duel with mandral bends so I know it has free flow their. It is that harsh rasp type sound an open exhust has I don't like any more. I have a Toyota truck with a glass pack so I have the rasp rice sound with that. please any sugestions I would like to here. I have went to you tube and heard a lot of the exhust notes. I also know that I can cut and remove the cat but how many horse power that GOOD FOR? Thank you all for your time and the extra 100 ponies from the v8 be nice but I lioke the small underdog motors.

If you have true duals, h pipe will work best. Keep the cats. Deleting those will add to the rasp problem. Quality mufflers is the next step. Larger chambers will help tone the rasp down. Borla xr1s are great on a true dual setup.

On six cylinders, quieter is better. I would definitely go with magnaflow. Don't cut the cats.

Thank you both! I just want do this right the first time no short cuts(learnt from my past you spend more money) and what I have for now works, and I was looking at both Borla and magnaflow. Both do make a quality product.

My friend had a Flowmaster on his 1998 Camaro and it sounded pretty good, especially pulling away from a stop sign. He did daily drive it and the muffler rusted out after 5 or 6 years.

I have the same muffler on my 3.8L and I'm thinking about taking it off and just putting a straight pipe in place of the muffler. Thoughts?

You won't like it. With a 3 inch I pipe a 3.8 will have a deep rumble, but once it reaches 3k rpm its gonna rasp and not sound appealing. Speaking from experience. Best system I have had was a b&b trifles exhaust. Little more subtle like magnaflow innthe low end but kept the rasp of the v6 tamed on a excelleration. But you likely won't find a system that will do a neutral Rev and nit get raspy and ugly sounding in the higher rpm.

Never did headers though so I imagine that would change the note a bit
