question about spintech exhaust

[fiveoho]

i have the pro streets on my car and i was wondering why spintech recommends multiple cats to run these mufflers. is it because they are so loud and cats will help quiet them down or is it because without cats, there isnt much backpressure?

thanks

Its because they are loud. But loud is good!

yes, yes it is!

i love my pro streets. much louder than my flows ever were and i like the sound better.

thanks man

so no worries with back pressure with these, right?
