Cat Converter or Catback exhaust first?

[Golbez]

I'm thinking about putting a random technology cat converter on my car, and a borla catback exhaust system. The car is a '98 Firebird v6. Would it be a better route to get the cat converter first or the catback exhaust? I want the exhaust just cause it looks so damn cool, but is it a bad idea to go this route first? I'm also thinking about putting some RK Sport headers on it a little down the road.

Just do both at once it will save you money.

agreed if not both at once at least with the catback setup get rid of the 90 s pipe right after the cat that will make your catback system actually more potent. The stock cat is already a good highflow cat but it is 3"in 2.25 pipe out so a 3n3 out would be better and larger so it would flow more.

I agree, get both @ the same time, if not just remove the reducer from the cat-convertor, & get the cat-back.

Hey Golbez, did you know we have a D/FW v6 f-body car club. If interested check the Venom-VI message board.

oh dont waste ur money on a random cat tho.. i would go with carsound/mangnaflow 130 or mac

the random tech has a heat shield that is of a different metal and will cause a buzz problem eventually plus results have shown little gain for the random tech cat for the price.
