wow. those hyper pak exh. manifolds are swoopy, thin and beautiful! Kind of remind me of a 2nd Gen Hemi manifold. Dutra''s are heavier-looking, and shorter. But you have to go with the one that is available, and Dutra's will do.
Oh yeah, pay the Dutra guy more for iron manifolds than any steel tube headers cost. My big old butt.
Listen, you want the perfect exhaust setup for a slant? .....well.....ANY American inline six with a firing order of 153624........here it is.
The inline six is perfect in that you can separate the first three and last three exhaust ports and there is one in each pair of three that fires every time.
So, a set of headers with dual collectors, and a Flowmaster wye tied into the pipes coming off the collectors going into a single 3" exhaust pipe is the best possible exhaust system you can ever run. you will have the serious advantage of one cylinder firing in each collector every time and helping to evacuate the last spent exhaust gasses of the last fire.
It's the best possible exhaust ever and hardly anyone ever does it because they get caught up in wanting gay *** dual exhaust like all the V8 guys......and they aint got a V8.
No way would I ever pay the gold plated Dutra price for short, stubby manifolds, when I could get some great flowing headers like Hooker.......but it's your money.
