Yeah, where it's straight. Then there are the bends, crush bends. They would be closer to 1" depending on how severe the bends are.Ferdie Dela Cruz said:From what i remember from the dealer telling me. They said 1 7/8 in I.D.
The factory exhaust is not mandrel bend, unless I missed something. Auto manufacturers do not generally offer mandrel oem exhausts because it is easier to make crush bends, less time consuming and of course extremely cost effective for themSmoothDaddyFig said:CRUSH BENDS????!!!!
I redid my stock exhaust and it was all mendrel bent.
This was bugging me, so I brought it up on the G20.net forum. This is what they also agreed to. See here:SmoothDaddyFig said:Alright...
...I looked at both my exhaust and the one under someones 91 XE. They are both mandrel bent. I dont know what gives, but, thats that.
The factory pipes on your Sentra when it came from the factory were crush bent. The types of pipe bends that manufacturers use are smoother than your typical Midas type shops. So you will not see the possible creases in the pipes and therefore it looks mandrel. But it is not. It is just a smoother transitional crush bend.massclassic said:I just installed a pace setter exhaust on my 93 se-r and the pipes I removed WERE mandrel bent.
Current OEM Prices for a '91-'94 Sentre SE-R (www.nissanparts.cc)I bought my pace setter cat back complete mandrel bent for 140 shipped---that puts cost to pacesetter at less than 80 dollars--which would make oem even less than that.
I would agree. Actually, in recent years more manufacturers are starting to use mandrel bends. Most of the cars getting the mandrel bends are more performance oriented cars. I should have mentioned that from my knowledge, most manufacturers between 1981 and 1999 use crush bends including Nissan/Infiniti. I do believe the Corvette with the Titanium exhaust is mandrel bend as well.Rocketman said:just a side on a side note.... The WRX does have mandrel bent exhaust from the factory. Kinda intersesting. I didn't believe my roommate until i saw it but it is. So yes oem's do use mandrel bends sometimes.
just thought i'd let everyone know.
Hehehe! It's annoyingly fun, isn't it!SmoothDaddyFig said:What gives?!
This is an interesting discussion and Im going bonkers!!
I saw the post you posted on the other forum. If Im wrong, I too will admit it with no prob. But from what I have seen under like 5 cars , its mandrel to me.
