exhaust leak

[johny24]

I got two cracks on my exhaust system one on my flex and the other on the cat. I have found cats on ebay but are they legal and also the flex where can i find another one i have been looking for just the flex pipe for the stock header.

If they don't look like a real cat, they probably aren't. If they're under 100, they probably aren't, especially if they're claimed to be a "high flow" or Hi-flow" cat.

i am having the same problem i am losing performance because of my leak. it is very hard to find a new pipes for the 420a because everything is for the 4g63 engine, but i have found a new flex on the autozone site for some reason its listed for a automatic instead of a manual. you have the buy a whole new downpipe which is like 140 bucks

magnaflow makes some really good highflow cats that are universal (so they'll need to be welded) but are priced at about 100 duckets.
