Exhaust Leaks
Hi,
My '70 Cutlass Supreme has the stock manifolds fed into a Pypes dual x-pipe system. The crossover pipe was cut and capped (factory single exhaust) and downpipes go to the Pypes system which is welded at the connections from the crossmember to the mufflers. Unfortunately, the shop I used last year isn't a good one but found that out the hard way. I noticed some noise upon coming to a light recently and decided to check out the pipe connections. The welds are not pretty, some small bits of filler rod was even left behind and there are 2-3 connections which have small leaks, slightly larger than pinhole sized. Additionally, both exhaust flanges where the downpipes meets the manifold are leaking.
Are there ways to fix this myself or is this something a new shop would have to address?
What are the consequences of having these exhaust leaks, will it do any damage?
