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?
