Have the J's header and thinking of going with T1R pipe and exhaust for the rest. Anybody know how this setup will sound? SG

 

with a test pipe, the sparrow's tend to drone out at top end.. i saw and heard of a clip where the guy had stock headers, test pipe, and the sparrows with a lil drone during vtec

the question for the other sparrow users out there - does the drone exist ANYWHERE in the rev if you keep the cat?

 

Info or speculation on perfromance accepted also. SG

 

I tend to think of drone as a constant on the highway at certain rpm's. When u say it drones at the top end I'm not sure what u mean? Highway drone or it just gets louder as it enters Vtec to redline? I heard from some that the Sparrow did not drone and I am wondering if that is not the case when u put a pipe on it. Thanks, SG
