Re: Sebring on Alfa 33.
forget all about sebring, thats overpriced garbage
if i were you, i'd go for CSC, they cost about half the price of sebring, and last way longer
i bought my CSC backbox 12 years ago for my first 33, and it's still like a new backbox
since then i have bought CSC exhausts for all my cars
another bonus is that a sebring will stay very loud, even on cruising at constant speed, a CSC will put on a very big mouth on accelerating, but is only slightly humming in the background on highwaycruisingspeed
my 75 TS has a complete CSC exhaustline, from the tubular manifold, a straight line into the backbox, so only one muffler front to back, and even that isn't too loud on the highway
