The Answer To Running Dual Exhaust In Your El Camino A Must For Any Engine And Transmission Swap Heavy Duty Construction Unlike Flimsy Tube-Bent Originals Racing Rated For Even The Highest Horse Power Motors Huge Dual Openings Allows Clearness For The Large Dual Exhaust Allows For Correct Alignment When Adding Aftermarket Transmissions Simple Bolt In installation With No Modifications Includes Frame Extension, Mounting Hardware And Instructions Eliminates the need for your exhaust to go under the stock crossmember and hang too close to the asphalt. How many out there are sporting custom flat pipes after a fast dip in the road?!! Heating and hammering the stock installed tube will pull the transmission over to the driver's side and out of alignment. Ever have a driveshaft let go at 7000 RPM? Other crossmembers (from A-Body Chevelles or the Grand Marquis) need to be altered and still don't have the correct mounting height. Out of alignment again! Also eliminates expensive custom pipe bending when using shorty type headers, which are designed to route your pipe under your oil pan, to the passenger side, where the stock hump is. Installation of dual exhaust when using this racing rated crossmember is a simple bolt-on operation that will provide clean, professional results. No floor pan modifications are necessary. Please Note: The 200R4 Transmission was factory installed by GM, beginning with the 1984 Model year El Camino's. GM altered the common frame configuration to accommodate the longer 200R4. Because the 200R4 crossmember mounting pad is further back than the TH350, a new design, stock crossmember was installed also. This stock crossmember mounts in a new set of holes in the frame on the driver side. The new holes in the frame can be identified as 14 inches rearward of the first set on the driver side frame rail. For reference, the TH350 factory crossmember mounts diagonally across the frame rails while the 200R4 (4spd automatic) crossmember mounts straight across. Therefore, pre 1984 vehicles will require the frame extension kit to install a 200R4 or a TH400 transmission.
