semi42 37 Report post Posted March 18 Hi guys anyone here with a tape measure can get me some dimensions of an OEM back box on the s2 My s2 has an Ansa back box and I don’t like how much the twin exhausts hang out the rear . I’d like to know how much different it is from the original. id like dimensions of x and Y if poss thanks Quote Share this post Link to post Share on other sites
peteyg 296 1 Vehicles Report post Posted March 23 Meant to reply last week! These are approx measurements from an SJS replacement backbox. X = 8.5 inches Y = 12 inches Pete Quote Pete '79 S2 LEW Miss September 2009 Share this post Link to post Share on other sites
semi42 37 Report post Posted March 24 Cheers for that, mines way off on dimension Y. It’s about 16 inches am tempted to take a hacksaw to it . The more I look at it , the more it grates. if it makes it worse I can always buy a new one Quote Share this post Link to post Share on other sites
peteyg 296 1 Vehicles Report post Posted March 24 Have you got a picture Steve? I've measured off a replacement 'sports' exhaust from SJ but the tips are thicker and, I think, stubbier than the original but probably only by an inch or so. I think I have an original somewhere buried under piles of crap in the shed so could check. 4 inches suggests it sticks out waaaay beyond the bumper...hacksaw time!

skiing 93 1 Vehicles Report post Posted March 31 I like the slightly slash cut pipes though - the slash cut pipes look similar to one or two S1 exhausts I have seen (including press pictures of the white original car) but they do not stick out that far! Ideally you can trim it but keep the angle? Quote Share this post Link to post Share on other sites
peteyg 296 1 Vehicles Report post Posted March 31 I see someone has chopped away the exhaust surround on the valance as well. My exhaust and the one in the background of the pic has much thicker tips than the original. Dimensions are about the same but original much finer which I preferred. I still have an original in the shed but clamp rusted to bits (same as one in the pic) and I've never gotten around to finding a replacement clamp to fitwhich would also involve chopping off and re-welding the stubby pipe on the backbox.
