kisthisSS Posted April 8, 2008 Report Share Posted April 8, 2008 (edited) I'm thinking about upgrading from the shorty headers and stock cats I have now to a set a LT's. Do you think I'll gain very much more from going with the LT's? Would it really be worth it? I like the Dynatech and OBX because they are direct fit. Looking at both of them, their design is almost identical as far as the header itself goes. I know the mid pipes are different and the OBX comes with resonators instead of cats. Do you think that the OBX's will be too loud and raspy with Corsa sport exhaust? I don't mind loud as long as it sounds good. Can't stand raspy! Is the quality of the OBX good compaired to the Dyna's? Edited April 8, 2008 by kisthisSS (see edit history) Quote Link to comment Share on other sites More sharing options...
kisthisSS Posted April 8, 2008 Author Report Share Posted April 8, 2008 Ok so I guess I should have done a little more reading before I posted this. I found a lot of info related to this topic. So I feel like a dumb ass. If I could erase this I would but I don't know how ha ha:) Anyway if you have anymore info feel free to chime in. If not excuse me for posting another OBX LT thread. Sorry Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted April 8, 2008 Report Share Posted April 8, 2008 FYI, shorty headers do nothing more than give you better sound, that's all. LTs will give you real performance gains, much more low end torque. Quote Link to comment Share on other sites More sharing options...
detjoe Posted April 8, 2008 Report Share Posted April 8, 2008 I was very surprized how nice the welds looked on the OBX. They have worked out the collector bolts getting lost in improved packaging. My clamps were bent but I think they will still do, but I dont think they are SS. I need to find the plug for the extra 02 holes...I was gonna throw some old spark plugs in there (ghetto) till I found some thing better, I could not find the 18x1.5 size for a plug??

orion :: SS Posted April 8, 2008 Report Share Posted April 8, 2008 ... I could not find the 18x1.5 size for a plug?? Replacement oil drain plug for a Honda - You can get one at Napa for $3. Been through this before with my 240SX, needed a plug for the wideband O2 hole. - Brian Quote Link to comment Share on other sites More sharing options...

LTs will give you real performance gains, much more low end torque. , Dan and I have Dynatech's, some have OBX's as well. OBX's are just the old style Dynatech's and require the use of plug wire wraps or some kind of contraption because of the driver's side OBX header comes to close to the wire and will melt it.

gixxerrider Posted April 9, 2008 Report Share Posted April 9, 2008 I have the dyna's. I have not had any problem at all. no melted wires Quote Link to comment Share on other sites More sharing options...
KissMySilvSS Posted April 9, 2008 Report Share Posted April 9, 2008 (edited) Do you have the new or older style Dyna's? The older Dyna's from a few years ago (NOW OBX) have a "hoop" style design and are notorious for melting plug wires if you do not use a protective boot. I have the new style Dynatech's that were installed in December and they are great! Not problems at all. The bottom header in the pic is what I am talking about in my previous post: Edited April 9, 2008 by KissMySilvSS (see edit history) Quote Link to comment Share on other sites More sharing options...
kisthisSS Posted April 9, 2008 Author Report Share Posted April 9, 2008 Do the new style Dyna's still have that little EGR tube sticking out of the passenger side header? Quote Link to comment Share on other sites More sharing options...

YenkoChevelle69 Posted June 16, 2008 Report Share Posted June 16, 2008 Are these considered long tubes or midlength? Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted June 16, 2008 Report Share Posted June 16, 2008 Are these considered long tubes or midlength? Dynatechs are LTs, I believe the OBX are also......... Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted June 16, 2008 Report Share Posted June 16, 2008 Both Dyna and OBX are long tube headers. They actually have shorter runners than pace setters however. They also have shorter collectors and smaller collectors than pace setters, but they both are long tube design, not mid length. Quote Link to comment Share on other sites More sharing options...
