'72 K20 LWB Exhaust System Recommendation

Any recommendations for an exhaust system for a '72 chevy K20 LWB powered by a 350 SB?

Talking with the only shop that does mandrel bends around my part of the state and they are suggesting the following:

Single Exhaust System
Manifold: 2.5" Ramhorns off a corvette
Tubing: 3" 304 Stainless steel (Mandrel Bent, of course)
Muffler: Magnaflow (I'm not wanting to be obnoxious to the neighbors)
Tip: Double Walled (cannot remember if he said chrome or not)

I'm being told that it should perform equal to or better than a dual exhaust system using 2.25-2.5" tubes with an H or X pipe, plus half the cost of a dual system. Unless I am looking for this to be a show truck headers will not give me anymore performance than the corvette manifold. Since I am not wanting this to be a show truck, but a truck that functions as truck and still looks and performs well, any suggestions? Is this a good setup? Plus other than the 3" tube coming out it will look stock.

Re: '72 K20 LWB Exhaust System Recommendation

A single 3" exhaust system will work perfectly fine for you since your not looking for tons of power and high rpm. You could even get them to tuck the tailpipe up high and turn it down behind the rear wheel so you won't even see it. The only concern I might have is the ground clearance with the driver side pipe coming off the manifold and going under the bellhousing. Your truck being a 4x4 might be fine seeing how it sits much higher then a 2wd. The choice is ultimately yours, but it would be more cost effective to go with the single and still sound pretty good.
