StashsZ28

I just purchased a 99 Z-28. All stock with a slowmaster added. First mods I plan on doing are the freebie mods along with a slp lid and k&n filter. As for exhaust I don't mind the sound of the flowmaster. Just that what I see is it's restrictive. I am down to one of three options. Have to run cats so not looking to run headers anytime soon. So hoping you guys can help. Option 1 is switch to a slp loudmouth 1. Option 2 dynomax 19418 ultra flow exhaust. Option 3 is just weld in a electric exhaust cut out. Thank you all in advance.....

I put an SLP loudmouth 2 on my 2002 and am quite happy with the sound. It's not overly loud but enough tone to know it's not stock. Has a real nice sound around 3000-3200 rpm and barks nice at wot.

You can have headers with cat's and pass the test... gives the car a nice tone and a few hp also

If you "like" the sounds of your FlowMasters (as I do), then keep them. It would be a waste of money to replace "just" the muffler if you are not planning on doing a full exhaust. I seriously doubt that the restrictions of the FlowMaster will make a difference in the "Real World".
