so I went with this xpipe to a local shop, they wouldnt recomend using just welding, since this part(12" long) is much shorter than resonator and requires additional pieces of pipes to be welded as well. they advise to use bolt on hooks, which raices install price to like $200-300.
Also, once of the pipes thats coming out from the header before resonator is at 90degree angle which leaves almost no space to attach extension pipe before it would go to xpipe.
anyone could recommend installer in Brooklyn NY or nearby?
