Please help me with my exhaust!!!!

[Jarhead79]

I'm leaning this way myself. There is a fella on ls1tech that insists one or both of my mufflers are installed backwards. Magnaflow clearly states that they are universal and can be installed in either direction, though he does have me thinking lol. I did notice last night that my shift linkage could be rattling up against the header on the driver side and on the passenger side it looks like the header is up tight against a boss on the block by the starter. I'm surprised I missed this, gonna have to pull the header to cut that boss off. Must have been excited to have the ole girl back on the road!!!

Other than for access to or easier removal, I'd toss the clamps in back and weld up the pipe or have a couple sleeves made and have them welded.

This is what I've done on the last three vehicles I've had and have really been happy with how they ran, my challenger really woke up when I changed to dual 3" mufflers and 2.5 exhaust.

That's good to know. I've also read where the transitions should be as gentle as possible, like on these Flowmaster adapters:

Welded up the rest of the exhaust last night. Sounds much better but still have a leak at the ball flanges. The clamps for the flanges are tight so I will try some high temp silicone on them and see if it manages to seal it up. I've been looking at other flange options and was thinking of trying a V-band but the joint at the collector is not 100%plumb and have heard I will have problems with them.
