Glasspack or Flowmaster 40 ?
I think you should leave it the way it is because if you think an actual muffler like the 40/50 makes it sound like a ricer than a straight glass Pac will drive u nuts haha, I honestly think it sounds super throaty and aggressive while wheeling ask the guys in the pa thread
, just a quick question do you normally drive it that hard to see 3k rpm, I have a 5speed and rarely see that unless I Wot her

Here's how it sounds now:
Here is before the glasspack with straight pipe and FM 40(listen to raspiness as the rpms drop and note this difference between the 2 vids) :

My friend put 40s on his and its quiet, i had a glasspack and I hated it. Now I have a 10 series flowmaster on 2.5 all the way back, I love it and its real agressive

I run mine by starting at 3k and running it to 5.5-6k 1-3rd then shifting to 5 whenever i hit 50mph unless im going up the mountain.. 4 banger FTW!!

Didnt mean to spin here, My front tires squeal if i turn going 2 mph it's fairly slick for what it is. My buddy spun all 4 in 4 low here.
Here's my buddy's in same parking lot.... He already sold it and realized implications of 4 low on pavement, it was 1999 sport auto np 242. He has 5-speed manual np231 1995 cherokee now. All he had was fm 40 and magnaflow cat.
