The catted AR downpipe plus JB4 map 2 sounds great, performs well, and doesn't give the smell nearly as badly as the catless variant. If you're in a garage with the windows down and stopped you might smell a little bit, or the car behind you might smell a bit when you're running rich... but again as long as you're not looking for the full power and just want the sound, smell and ability to run map2 it's definitely worth it. Running AR catted + vanguard exhaust the car sounds like a beast.
Thanks. That's pretty much what I was looking for. What were your dyno numbers? So smell-wise, windows down @ a stoplight.. would you smell it? That's like the biggest thing for me lol. I don't know how it doesn't bother lots of you guys. Everyone seems to notice mine.
