You can offset the cost of the exhaust system by using a Summit or Jegs G-body dual kit, both of which are mandrel-bent. The Summit kit is made by Heartthrob in Minnesota, so if you are a Made in USA fan, I recommend that kit over Jegs which is 'imported'. I have to go back an review your threads, but I am guessing that you are keeping the BOP transmission that was behind the 3.8. If so, the TH350 dual-hump crossmember should fit just fine and enable the true duals. The remaining expense is custom-bending manifold extensions to match your Olds. Maybe Chuck and JWobble can collaborate. Fewer custom exhaust shops in New Mexico....

From everything I came across checking in on the Jegs kit last year it's a Heartthrob kit. All three use the same "test" car pics & instructions for the kits.

Ah. I spoke to the Heartthrob folks about a dual kit for the K10, having bought similar systems via JC Whitney 15-20 years ago. I mentioned the G-body kits, whether they could make me behind-the-wheel tailpipes. The guy laughed and said, WE made those for Summit and Jegs, though Jegs is now getting them overseas.

I got a set of Sanderson headers, a Pypes regal style 2.5" system and tied in the drops. Took a double hump crossmember with a slight modification, elongated the slot for the trans. 82 cutlass with Olds power 200R4 combo. I played at it and still had it in in a day.
