borla 1 5/8 headers on a 99...what rwhp

[ASKYOURWIFE]

Borla 1 5/8 headers....

ive got a 99 currently making 428/473 with smooth tubes and cat delete..

What would these headers give me with NO tuning...As well what could i expect with vec2 tuning and these headers?

Also what do they sell for brand new?

THANKS

Think Borla have stopped making them I tried to order a set but they were no longer available.

the VEC2 is probably good for 20rwhp or so and the headers maybe 10-15 if tuned i bet.

if you're going to go S/C'd in the future, get 1 3/4" headers

I have them for sale in the classifieds. I got 448RWHP and 479RWTQ with Borla 1 5/8" & B&B catback and cats. The borla's should be good for 15-18RWHP. They definitely help with mid-range torque and HP. I posted my Dyno results here in Jan. Search for 'Dyno Results'. I have an '01 RT/10.
