Banks Exhaust System

[PAJeeper]

I am in the market for a new exhaust system and am leaning towards the Banks rather than the Borla. I have heard that just the Stinger alone can give you upwards of 25HP. Anyone want to comment on that? I would also like to know how difficult it is to fit the header assembly to a TJ.

I gotta replace my manifold as well and was looking at going with the Banks setup. I believe mine's cracked, but haven't actually checked it out yet. My check engine light comes on after about a day after resetting it, the two O2 sensors I replaced were crispy critters, and it does make an unusual noise during throttle. I'm guessing this points to the manifold being cracked like just about every other 4.0l TJ on the road. Oh yeah, gas mileage blows as well .

Suddenly the words 'Wrenchfest' and 'Guinea Pig' spring to mind. I dont know why.

Okay, I give in. I'll be the guinea pig ........you buy the headers and I'll be down with the TJ for fitment .

I've got the Banks in mine since Oct/Nov 03. My header was cracked and decided to do the install before it got really cold out. (Inspections up in March). Anyway, it wasn't too bad of an install.

No performance gains that I could notice...and the noise I thought was from my cracked header, is still there. I've rechecked the bolts and they're all tight. No leaks that I can detect (no exhaust odor in the engine compartment and a couple guys that had leaks stated the header would glow orange...which mine hasn't done)...so I don't know what's causing my problem. It makes a ticking/hissing sound under acceleration.

I doubt you'll get 25horses out of it either. But the lifetime warranty was the reason I spent so much...if...err, when it likely goes again, I don't want to have to buy a new one.

I'll offer up some help if you want a Wrenchfest.

I'm pretty sure the claim of 25 horses was for the Stinger not the header.

25 seems like a stretch, but who knows. I have Banks stuff on my truck, it did increase the performance, mileage and decreased my EGT's (it's a diesel thing.) Overall, a little pricey but high quality products.

If I was going to replace my exhaust, by the peice or the whole deal, I would go with the Banks system. I like the Borla system also, but if you see them side by side, The Banks looks beefier, especially at the flange mount.

As far as HP claims. 25 sounds high for just a header change. I would hope that they can show some form of independently done dyno charts and data to back that up. Was that a real world or controlled environment test? I dont know about how Banks came up with that number, but did it show at what RPM it came from. I have seen high HP numbers that were at 5000rpm's. My Jeep dont hit 5 grand ever. I doubt that engine could handle those rpm's for long.

Now replacement of the entire system, including a hi-flow cat and a decent breathing intake as well may start making hp gains like that. But generally torque numbers will fall as the flow improves.

My plan is to run what I got untill something fails or breaks. Then replace it with aftermarket parts. I'll use whatever brand catches my eye at the time. Other than that, I feel that the gains to be gotten are few.

I don't think you get the HP improvements unless you install the stickers as well . I''m not looking nor expecting to gain anything other than the piece of mind from replacing yet another piece of half assed OEM junk .
