Supersprint Headers and secondary cat Install?
Hello Friends,
I currently have a secondary cat delete and just purchased the supersprint headers and want to tone down the noise...
Question: Any recommendations on a secondary cat re-install or sum such to tone down the noise?
Thanks in advance!

I had the same setup. Installed headers, and it was too loud for me.
I re installed my 2nd cats, and it was much better.
So now i have LTH, 100c Main cats, then everything factory after that (2nd cats, res then mufflers)

I just purchased a pair of 200 cell cats by flowmaster from ebay for the same reason. Haven't had time to install yet unfortunately. Hopefully I'll have feedback for you on noise reduction soon. They're $85 each I believe

ARH LTH -> ARH HFC -> X Pipe -> 200CEL HFC - Mufflers.
Toned down the exhaust by about 15% with the additional secondary cats, but the flow is still similar. If you get a good set of cats, you are looking at 2 to 3hp loss.
