i looked on the search and i didnt find any thing, but does and one have an ERZ up pipe? if so does it fit good, no leaks. becasue i heard and have seen that ERZ's down pipes are not so good with fits and they are a little troublesome. let me know what ya think if its worth the cheap coast to get one.
i have one and its great. i've never heard of anyone having issues with them. i know ppl have had some issues with their cat back but not their up pipe or downpipes.
I had to cut my 2 rear studs down ~1/4" to clear the downpipe but seems to be working no problem since.
or you can take the studs out of your existing up pipe and use those. good point though i forgot about that issue.
It's a nice piece. Welds look good. I had one for a while. Ended up swapping out for an HKS one because of a problem with the sensor in the uppipe that didn't want to tighten. It wasn't the ERZ pipe's fault though, it was the probe.
