Reweld the downpipe after clean the rust

[Speed_Senpaii]

Hey guys so I got this used PRL downpipe around 9k used , not bad for downpipe but little rust and dirt , I am planning to clean it and put more weld on these area then maybe ceramic coated plus blanket once all done , is it ok to weld more in these area or let it be ? I got the front pipe new one and new turbo but this PRL has been used I thought maybe make it fresh and cleaner more also put ceramic coated to help the life span , thanks in advance

i wouldn't weld it unless it's leaking

Tough question my welds just gave out on my PRL catted downpipe after buying it second hand . If I could redo it all I would've done a touch up on the welds just to be safe and for the long run.

That what I was thinking because I see some downpipe split in two after long run, this has been used for 9k I just think maybe reweld to make it stronger

I would honestly do! My coworker offered to reweld mine but I'm just hesitant to remove it just because it's I don't know how much is together

I am also think to reweld maybe next week after that probably wrap with heat blanket since I can't use the heat shield anymore, the downpipe too fat for that

That's perfect! And if I recall you could I have the top heatshield and main one on. Doesn't hurt to try

Good oppurtunity to take apart & go full catless, if so inclined. Then weld her back up & good as new

I honestly thought about the same thing

I have a RV6 catted DP & I had thought about going catless. Two things held me back: catless pipes are hard to find; & my current pipe is caramic coated for heat protection. The nice thing about RV6 DPs is they're a two-part design. So I removed the lower section & gutted the cat. It woke up the car even more.

I'd say, if you're considering it then go for it. Worst case you find another catted DP if you decide it's not for you. Someone would buy your modified "catless" from you.

Just my 2ct

In this pic, I can tell the weld held up fine. The metal around it gave. Even if you add more beads on top of what’s already there, the metal near the welds is what will fatigue eventually.

So would you consider reinforcing it or will it be a lost cause?

Not unless live in free smog check or emissions test area
