Pressure bends vs Mandrel bends for custom exhaust

First of all, I DO NOT want to buy an aftermarket bpipe.
After reading this: http://www.nissanperformancemag.com/...revenge_nerds/
I want to buy mandrel bends to do my exhaust.

I can buy a few of these and make my Bpipe : http://store.summitracing.com/partde...8&autoview=sku

I am debating whether I want the exhaust shop to weld the custom bpipe like 20 times. I can get the pressure bent bpipe for about $65.
What do you guys say? Is it worth getting the mandrel bends and having a bpipe that has been welded a couple of hundred times, or should I just forgot that idea and get a pressure bent Bpipe?

Also, this is the resonator I am going to get: http://store.summitracing.com/partde...=KeywordSearch

I still need to decide on the muffler I want..... Exhaust has to be one of the most frustraiting things to think about for any car...
I need some comments and tips for my exhaust.

IMO dont buy pressure bends. I know youre not wanting maximum power over everything else, but you cant beat mandrel quality.

For the muffler, my 1st pick would be Stillen, but the Magnaflow 14827 is a hot lookin one.

Quality?

As far as durability and fit goes, you'd get more for your money by having a shop pressure bend a 1-piece B-pipe than having them weld up a mandrel bent pipe from a bunch of pieces.

multiple welds on the mandrel-bent tubing? I would have the least amount of welds possible with a pressure-bent tubing than that.

My budget is SS and mandrel, with a magnaflow resonator...

I think for an NA application, pressure bent vs. mandrel bent won't make too much of a difference.

Do not get that dynomax thrush glasspack. I believe it has a louvered core which is terrible for performance. I have one of those dynomax bullets, and it does a pretty good job.

It says its perforted, so which one should I get? I read that you got the muffler I want, you got any sound clips?

yeah, on N/A, does not matter if it is pressure bent or mandrel bent, It will probably make a bigger difference on a boosted max, but even at that, it wont make too much of a difference.
