Re: Advise on Exhaust.
The delta 40's would work good with a dual 2.5" exhaust. The only problem I see is that I hope you can find a shop willing to make the pipes for you.Most shops nowadays won't eliminate the Cat's on a car or work on an exhaust without them.Also finding a shop that can figure out how to route a true dual exhaust on a third gen. since you can't take a pipe over the driverside of the rear end housing, the panhard bar is in the way. Also, the driverside trans crossmember isn't desiged for an exhaust pipe to pass under it. The best way to do it is to run shorty headers an then run both pipes down the passenger side and over the rear axle, then mount both mufflers where the stock one was, and then run both tail pipes out the drivers side. The other option is to run Edelbrock's tubula exhaust headers (these are shorty') and their 3" Y pipe. Hoo this to the Flowmaster American Thunder 3" dual outlet kit. This is a 3" sigle exhaust that mounts in the stock location and has dual outlet tips on oposite sides of the car. Join the 2 with a peice of 3" tubing and your good to go. This you can install yourself in the driveway. If you have a shop install, use a Magnaflow high flow cat.The new high flow cat's won't take any power away fom the car, but will keep it legal. Also the cat will quiet it down a little putting aruond town, but it'll still draw attention, but wen you open it up it'll still roar. I had a 90 Formula with the Edelbrock headers, stock dual cat's, and a 3" exhaust with flowmaster dual outlet muffler with a TPI 350 (ported heads, big cam, etc.) adn a 5 speed and the sounds this car made at WOT was incredible. It was still loud at idle and cruisig speed, but not enough to draw the cops attention.
