OK I'm getting ready to junk the factory exhaust on my Iroc. It has the stock 350 TPI in it for now but soon it's getting a new top end and I'll be looking at 400hp at the wheels.Emissions are no concern. No testing here.

I've got two options I can take and need opinions on which route you would go.I'm useing ceramic coated Hedman longtubes.

Option I
I already have a dual 3 into 4 Mufflex Y pipe I picked up from a buddy. I can mod it to connect to the Hedmans and run a 4in catback with a Spintech or Flowcrapper muffler.

Option II
Run duals off the headmans with an X pipe and Hooker mufflers with turndowns under the back seat.

I want to keep ground clearence and my car will never be lowered extensivley.

I plan on building a new crossmember to keep the pipes closer to the body which ever system I run,as well as modding the floorpan under the rear seats to keep the mufflers closer to the body and keep ground clearence.In the future, once I replace the panhard rod and upper brace with tublar pieces I'll continue the duals over the axel and out the rear.

What would you do?
Sell the Y pipe and go with the duals idea or keep it and run dual 3 into 4 and send it out the rear with a Spintech or Flowmaster Raceflow muffler?
