exhaust manifold

Is it necessary for the exhaust manifold to be port matched to the head? I don't remember the previous one being out of round & I've already returned it. Will this be an issue? It's the 4th manifold in 6 years! I'm not sure if that's good or bad given what I've read. I've replaced the...

Flying to AZ in March to change my 2005 exhaust manifolds. My friend's tool set is pretty basic and my tools won't be accessible. I'll also be removing my driver-side fender for the first time. I've purchased: 14mm swivel socket 14mm adjustable ratchet wrench nickel-based anti-seize Note 1...

I’ve been reading these forums for a decade now, I’m familiar with many of you and have read thousands of posts but I’ve finally decided to make an account. I’ve got a 97 tj sport 4.0 stock, possible 1” lift.. (new engine..jasper😫) the old 4.0 overheated and blew a piston ring and my headers...

I have a 1999 Jeep Wrangler 4.0L. When I first purchased the vehicle over a year ago I had replaced all the exhaust on the car. I had replaced the exhaust manifold with the Banks exhaust manifold type version. It wasn't by Banks but an exact design. Then earlier this year it cracked and I had to...

2006 TJ 4.0 6sp Rubicon I have an exhaust leak from the flange joints between the two front catalytic converters and the exhaust manifold. I tried tightening the flanges but I can still feel and hear exhaust leaking. I managed to remove the 4 rusty flange bolts and get the joints apart, and it...

Hey guys! I've got a 2006 TJ with the 2.4 and a 6 speed. It's got a strange rattle on acceleration. It almost goes away when the engine warms up and it's not near as bad now that the weather is warmer. It was horrible this winter. It'sbeen getting progressively worse overall though and I've been...

I was wondering if any of you have used the Novak block hugger headers for a TJ Gen lll swap? If so, have they been reliable, leak free and have you been generally happy with them after putting some miles and years on them? So that's the primary question but to expand a bit if you care to read...

Hey all, happy Sunday. Scouring the Interwebs for a pair of exhaust manifolds for my 2000 4.0 ... easy to find the one-piece manifolds for <$100 for the older TJ's, but can't seem to find anything for the two-piece newer TJ's. Would anyone trust this eBay listing? Supposedly "corrosion...

First post so hopefully I'm going about this the right way. I'm replacing the exhaust on my 04' TJ Unlimited from the manifolds to the exhaust tip. I went with Omix-ADA manifolds, fel-pro gasket, all 4 NTK O2 sensors, Magnaflow OEM direct fit downpipe/catalytic converters, and Banks Monster...

I am replacing the manifold gasket on my 2.5L. I want to know if I have this right... Pic 1 has my assortment of bolts with 3 different washers... The weird looking washers hold against both the intake/exhaust manifolds, correct? The round washers hold against the exhaust manifold only...

I need to replace the exhaust manifold gasket on my 05 TJ Wrangler X with the 4.0 6 cyl. The job doesn't look that bad, and I really don't want to pay $400 in labor to have a garage install the $30 gasket. Anyone done this? Anything to be aware of that makes it tricky?

Anyone have any tips or suggestions for removing the intake manifold (going to install my supercharger) on my 05 Wrangler TJ? I know how to remove it, I was just curious if there's anything I can remove or do to make the process easier? Thanks in advance!
