Secondary cat delete - best decission ever :)
Hey guys - just wanted to say thank you for all the tips about the secondary cat delete.
Took my exhaust off this week and opened the secondary cat box and took them out.
everything welded back in place - looks like original and like noone ever touched it.
sound is so amazing. could stomp on the gas all day long.
love my car even more now

NONE! I had mine done today and it is awesome! It just amplifies the stock sound, a bit deeper, not quite as raspy in the mid range, and just plain MEAN! With a tune, downshifts are so much more fun! I drove home 8 miles from the shop and killed a quarter tank of gas haha!
Startup, sound is nice...that first rumble is great and you can immediately tell something is different. Once revs drop, just like stock.
Revs are something you gotta hear in person to understand...its phenomenal!
Low end, sound is great...a bit louder, but throatier.
Mid range, sound is louder, deeper, and a bit smoother, not quite as choppy sounding
Top end, sound is crazy loud, like stock but not quite as high pitched, deeper/throatier.
