Did you (or anyone else) have mild rattling/grinding sounds below 1800rpm when beginning to move from a standstill? I couldn't quite figure out which nuts and bolts to use when mating all the pipes together- going from studs on oem to not caught me up. I ended up using a mixture of oem nuts/bolts/studs and the prl included ones. I used only prl bolts and two copper-coated nuts I bought to fasten the dp yo the turbo.So finally got the downpipe on and I'm very impressed I'm running ktuner stage 2 and adding the downpipe you can feel some gains and hear the turbo alot more. Using pb blaster made getting the bolts and studs off a breeze I sprayed them over the course of 2 days and they came off easily. Only downside is The cel but I'm going to clear it with ktuner later today. The exhaust note is louder and deeper I'll post a video soon! Lemme if there are any particular things you want to see or hear in the video.
Tldr prl downpipe was worth it!
EDIT:
I think I figured out what I did wrong that is likely causing the sounds. I re-tightened the DP brackets to hold the PRL DP in place before I fastened it to the turbo, so the brackets were positioned under/toward the rear of the car relative to the bottom flange on the DP. I never changed it back, and tightened the brackets on the rear side of the DP after I began fastening all the new pipe connections. That, and I did not use the two bolts with large washers to secure the brackets to the DP- I used the two OEM turbo/DP bolts and two of the PRL-supplied locking nuts.
Is this going to cause harm if I leave it like this for a week or two? I do not have the time to correct things this week, and will be away on vaca in the boonies all next week. Laaaaaame... So pissed I f'd it up.
