Another exhaust question
I was curious if anybody here has L/Ts, cut-out, and still kept the stock exhaust. Its an idea that I have been throwing around, and I wonder if ne one has done this, and could give me some feedback.
I love an awesome exhaust note, but at the same time I have my days where I could really go with-out, so keeping the stock quiet exhaust and throwing some l/t's, ORY , and cutout seems to be a way for me to have my cake and eat it too.
Also, what would you all recommend for doing this, bc I was thinking Pacesetter L/t's and a single 3" cutout

Lt's and Ory will open it up a bit under stock catback.
Right now on my 01 i have pacesetter lt's ory, 3" cutout right befor the axle and a magnaflow muffler.
I went with a manual cutout but you can always get an electric coutout.

I did exactly what you are contemplating before I went with true duals.
Initially I had only the cutout with the stock exhaust. When open this was good for 15rwhp and 19lbs-ft rwt.
I then had QTP LT's with a custom ORY (!cats) feeding the stock I-pipe onto which I had previously welded a QTP E-cutout. The balance of the exhaust was the factory installed items. Very mellow when closed. Very loud when open (at WOT).
When I dynoed it the difference between the open and shut cutout was only a 3rwhp and 5lbs-ft rwt.
In order to produce more power I ended up going with the LT's into TD's with an X-pipe feeding Magnaflow mufflers with 45 deg turnouts at the axle.
BTW: If not for racing the car and trying to gain all it's got I would have left it with the LT's, cutout and balance stock.
