hey,

got some questions on exhaust dimmensions for my rex, i searched but everything i found is in relation to aftermarket stuff. i'm putting a b7 into it and don't wanna spend big on the exhaust, one cause i can't, two because its only a stock 1500cc and i don't think i need any sort of 2"+ exhaust system. i'm thinking of ordering a crx si factory catback for it, does anyone know the size piping they use for this? also does anyone know offhand before i go test fitting if my stock Hf downpipe will bolt up to the B7 manifold because i don't have the downpipe for the b7, if not what downpipe should i use? a stock Si one?

thanx guys

eric

 

1-3/4" into 1-1/2"

the HF exhaust wont bolt to anything besides a HF manifold
