Definetly. I certainly hope no one would assume a cat back would give near the gains as headers.ShaneD_06GTO said:Save up for headers. Like what was said above, the HP/TQ numbers you get from just a catback aren't that impressive. Headers and a tune really wakes these cars up. JMO
Umm thats not true. Stock piping is 2.25" Corsa and Borla and Magnaflow are all 2.5" and SW is 3". Not to mention no crimps. On a stock car you wont gain much but sound from a cat back. On a cam or cam head car with headers you will gain some hp. 10-15rwhp.Freedom_Fighter said:IAftermarket cat-back systems are the same diamator as stock piping only different you'll see is mufflers and resonator!
If I had to do it over again, I would do the headers first and if you arent happy with the sound then change mufflers or cat-back to suit your taste.mypetgoatAZ said:Id like to buy the Kooks set coated w/cats, but I dont think I can swing the $1375.00 right now. What I can swing though, is a Borla cat back for $900.00. What do you think? Also, opinions on the Borla system.
