SLP exhaust is 2.5" and Stainless Works exhaust is 3". Which one would be better for our cars?
MSRP for the Stainless Works exhaust is $699.

Exactly! I had a 3 in. mandrel bent setup on my 62 BelAir with a 502 big block and could have got by with 2.5 in instead. Would have been alot easier to route on the car, especially around the rear end, where I had air bags in place of the coil springs.Adam4356 said:Difference isn't gonna be that big power wise. The Stainless works exhaust being bigger may give up some ground clearance. Both seem to be great systems. The chambered stainless works exhaust will be the loudest i predict but a loudmouth setup SLP will be pretty close.
All in all i wouldn't worry too much about pipe diameter. Mandrel bent is the biggest requirement. True duals don't require the sewer pipe that fbodies need so basically a true dual 3in system is setup to flow for alot more than the stock motor can throw at it.
Exactly what I was thinking when I read that in the Helm's. 2 PSI backpressure normal at 2,000 RPM? Holy Smokes! We might be looking for good shorties but paying attention to length as a divider of 32 or 34. Anyone know what length these motors 'like'?FLORIT said:I can easily believe our stock exhaust provides very low back pressure. See the "Burbling and Backfires" thread. Some of that noise is cam related, but having a free flowing exhaust helps give our Goats that throaty muscle car sound. I'm looking for headers that bolt into the existing tail pipes and based on what you're saying I don't NEED to buy high flow cats. Cool.
