Good exhaust shop?

Some things to remember, guys... Unlike the Jeep 4.0L, my 3FE has two manifolds, one for the front 3 cylinders and 1 for the rear 3 cylinders. Two separate 1.5" downpipes lead to separate side-by-side cats, then to a y-pipe, into 2" pipe all the way back, and there are a LOT of bends on the way. The only straight piece of pipe in the system is the tailpipe behind the rear tire, and it's about a foot long or so.

pipes

yes, They are small, but bigger is not always better, that being said i haven't ever played with headpipes on a cruiser before so i don't know how it will react, I guess it could make a difference good or bad. whatever difference it will make, it will be a small amount. If it were mine i would spend the money elsewhere. that's my honest opinion. If you felt compelled to up-size, i would try to find some pre-made mandrel bent downpipes, the cost will probably be close to the same and it will flow better. when i bent tubing it shrinks the pipe in the bends, so if i build them in 2" through the bends it will be more like 1 3/4" so it would kind of defeat the purpose. As far as the lots of bends go, yes less is better but it really isn't going to make a difference. the best thing that you can do is go 2.5 tubing from the y-pipe with a good muffler (flowmaster,magnaflow) all the way out. that's where you'll notice the biggest gains. plus it will sound good!

Ok. I'll probably just have you install the O2 sensors for me then.
