Does anybody think it would be necessary to weld the inside of the flanges for the b-pipes, and catback system to make a smooth transition from one joint to the other. I know the flanges have some wiggle room for fitment and adjustment and the b-pipes and cajun catback that I have ready for install do not have the flanges welded on the inside. The reason I even bother bringing this up, is it doesn't seem that many forum users talk about the small things like cleaning edges of flanges, only bolting on systems and calling it a day. I'm sure some technical savvy individuals like milenko, PR and others might be able to provide insight if welding and smoothing the transition joints is even worth the effort. We all prefer mandrel bent pipes, but what about the transition pieces and the rough edges? I think it couldn't hurt to put in the extra effort to smooth out the rough edges of the internals, probably the most important part IMO. Anyway, I have headers and b-pipes ready to go in, just waiting on uprev to support my ECU p/n and seymore4 to get me a base tune to get up and rolling, in the mean time, should I clean up the rough edges? I have a tig welder and air tools to do the job. Would it be worth the trouble? Thoughts?

in short, not really. for the average modifications I don`t think there would be any noticeable gain.

laptop battery low, gotta go...

I have some flanges that are leaps and bounds better than what's in the picture. Note the gasket and the bottom flange are nothing alike. Cajun Laser cuts off the oem Nissan gasket for better seals.

Jeff,
Those aren't your products. The piture is from prt performance, the b pipes I chose...don't hold it against me!
All, cajun b pipe products are top notch. You will not be disappointed. I wasn't terribly impressed with the tig welds on the prt performance pipes, but they look to be sufficient and will likely be leak free.

Cajun flanges are far superior to the PRT flanges as well as the cats I use. Not to toot my on horn...:)

Installed long tubes, b pipes and all supporting mods this weekend. I found the install a chore, especially on the drivers side....(4x4). The PRT b-pipes I have will likely go in the trash tho...the fitment is garbage. One of the pipes was about an inch shorter than stock and wouldn't mate up properly. The drivers side bpipe o2 sensor bung was positioned on top of the pipe and was making contact with the bottom of the cabin floor...which is a no no since 1 o2 sensor cost more than the entire set of b pipes. Unfortunately, until now I hadn't heard much about the prt product line, so I figured I try them out. Another forum member has already confirmed that he had similar fitment issues...Classic example of getting what you pay for. Jeff, I sent you an email. I will need pipes...

Some goodies. I was rushed by the Mrs. to finish and meet before dinner with the inlaws so picture time got cut short.
