Is there a big difference between a stock exhaust manifold WITHOUT the cat converter, and a new header?
I couldn't find an answer for this.
I found this:
https://www.summitracing.com/int/parts/ ... refilter=1
It's listed for an 02-06 sentra, but I think it's the same 2.5 engine on a 4th gen Altima. Would it fit?
