i have an 86 firebird originally a 2.8 v6. it now has a rebuilt and worked 350 from a caprice in it. im trying to find a suitable exhaust preferably 3inch duals staright back with no cats. in my town there is a garage the does custom bending but it only goes up to 2 and1/4 inches. also my engine has the stock manifolds on it and space is tight. are headers an option? thanks

 

2 1/4 duals would be Pretty good..

 

would ther be a significant difference in sound and/or power

 

I wouldn't know why not. And pardon me for saying so, but I still simply don't understand the idea of true duals and the annoyance of trying to fab and fit them under cars they were never designed for. Sorry, just my old man rant. I'm not claming that the following system is the best, but it's a pretty cool 3-inch system from the collectors back and works well with my 350/330: Hooker 2055's (Jeg's 520-2055). Catco high-flow converter (Summit CTO-9118). Hooker catback (Summit HOK-16823HKR).
