I have used them before and from now on I will always use them.
I HAD Bassani Longtubes on my car and I HATED the way they fit.they hit everything in sight and wrapped around the steering shaft too.
I sold those(poor buyer
)
I bought some 1.75" BBK longtubes this week and they went right in the car in about 15 minutes and clear everything.
no more wrap around the steering shaft amd no more noise from them hitting everything else.
and MAYBE a few more HP
