I'm looking too. For me, it's going to be a toss between the JBA shorties and the Bassani mid-lengths, but if the Bassanis can show some good gains on an n/a DOHC better than the JBA, that's what I'll get.
DONT GET JBA! haha crappy quality and over priced. go with bassani all the way. i am getting my midlength soon. youll look around 20+ft lbs. on the low end and about 15+rwhp gains with those midlength. JBA wont even go more then +8rwhp. dont bother with those.....
I have them on my 99. Just got it back from the shop (total rebuild). So I cannot give you before and after numbers.
I had a Bassani X and Cat back before the rebuils and now the sound with the headers is sweet. Deeper tone and a bit louder.
I love them because of the ground clearance. My car is low and long tubes would drag on speed bumps.
These header are great.
Prices are all over the place - but I got mine ceramic coated from Dugan Racing. They gave me a great price - check with Tom at Dugan Racing - his customer service was awesome.
