Hey guys, new to the t/y forum and new tahoe owner. I recently put a borla cat back 140193 on my 07 tahoe (http://www.summitracing.com/parts/bor-140193/overview/year/2007/make/chevrolet/model/tahoe), didn't get exact the sound I was going for. Was wondering if I swapped out the muffler with a xr-1 or a pro xs (both borla), would that give me a better/meaner sound? and which one of the two? any help or suggestions is appreciated, thanks
