TTI 2.5 dia system install on 68 dart 360 cu in.

Any one have problems with clearance problem next to 90 degree oil filter&pass. side down pipe? These are stock 340 manifolds and are correct as I have owned 2 cars before.
The rest of system w/ H pipe installed with no problems. Seems like down pipe is resting
on my oil filter. Any one have wisdom?
