i took a look on pasquals site,i had a good look at the exhaust you mention,the csc one?.it looks identical to my 'alquati' one,if so,its a good quality item,the welds etc are very good,as is the chrome plating on the end tip,it fitted very well too.
i had to lengthen the strap part of my exhuast clamps tho,easy enough,i used some 1'' flat welded on,then simply hammered the curve in to suit.
forgot to mention...it sounds great to!,got my friend to drive mine yesterday,first time i've seen and heard it in motion.........her first 126 experience.and her main comments? she loved the turn in of it,now knows why i drive like i do!!!.............and also loved the the 'power' delivery............so next time a 600 odd euro parcel from NANNI comes i'll get less ear-ache!!!
