I thought I'd check Ebay for an X-pipe, since they are $189 new from Dr. Gas (2 1/2" x 2 1/2"). I ws surprised at the number of different ones offered, and how much less costly they were than the name brand ones. Having always been taught that you get what you pay for, these cheaper alternatives set off some alarms in my head. Anyone have experience with with X-pipes of one brand or another? Thanks. John B.
I bought mine here: http://shop.store.yahoo.com/exhaustpros/hustxpi.html Main website is here: http://shop.store.yahoo.com/exhaustpros/index.html They are designed to improve on the idea of a 'crossover' or 'H- Pipe'. H-Pipes are a straight pipe between your dual exhaust pipes (90 degree angles). The idea of both is to balance the exhaust pulse on the cylinder banks to assist in scavenging- ie. getting the spent gas out. The X-Pipe improves on the process by eliminating the resistance of the right angles. It also gives your exhaust tone a bit more of a snarl. I think all of this is right. It's the way it has been explained to me over the years. Seth
The X configuration tends to improve performance at a higher RPM than an H config. The X tends to reduce exhaust levels by the more direct cross interference and changes the sound to a nontraditional buzz or humm type sound at RPM. The X config also give each bank access to both sides of the muffler system, reducing flow losses. This tends to be where the gains come from in addition to the pressure pulse changes to each bank.
I got my 3'' kit from Summit it includes clamps (that im not going to use) X junction,and extentions.Its really nice and i cant wait to get the engine back in the car hook up that X pipe with the bullitt mufflers and hear it scream........
I went heddman headers (black painted). 2 1/2 w/ X-pipe and raven 30 series mufflers. When I went to the X-pipe I noticed alot of things changed. The tone was the first. It went from a loud rumpety camed sound to a well worked fuel injection engine. What I mean by that is it sounds a little mellower but accurate, clean sound. I pull in to car shows and the first thing people say is the exhaust sounds amazing. The best is when you get on it. It Growls, totaly different than the straight pipes almost scary. Does anyone have pictures of the heddman elite headers on their car. I wanted to see how they look b4 I buy them from Autokrafters. Can you ding the elite headers for fitting purposes or no? Mine I had to ding and make a bracket to keep the powers steering assembly. Actually my dad did this not me. Thanx eveyone in advance for help, Thom
hey Parttime, does it seem mellower than the dual exhaust? Did you notice an improvement in performance?
Buy elite headmans do you mean the ceramic coated ones.Thats whats on mine 15/8 primaries and with the coating.I like them alott.
I have the coated as well. love em. people wil tell you that the coating does not hld up, and maybe for them it didn't. But mine look like the day I bolted them on. Clean look but my car also lives in a garage when it is not on the road. Scotty P
Elites have a different coating than the the HTC. 259.99 for elites 309.99 or 329.99 for the Htc coated.
74 Mav. I'm sorry, I cannot honestly answer your questions. You see, I did the 6/8 cyl. swap. It was all new when the swap was made. I have nothing to compare it too. But it seems to breath good and sounds nice.
