I have to re do part of my exhaust to improve ground clearance.

Currently I have my intake restricted all the way down to a single 2" hole to make 297/260. Missing the 308/258 I had with lt1.

My current exhaust consists of 2.25" pipes that Y into a single 3" pipe through a dynomax straight muffler. Pretty open.

I was thinking maybe running some 1.75" pipe straight off the manifolds, for a short distance before going back to 2.25" to connect with the rest of my system

My thinking is this could possibly increase low/mid range exhaust velocity/scavenging, and gain me some low/mid range torque while acting like a restrictor at higher RPMs? All done in conjunction with taking out some intake restrictor of course.

Worth a shot?
