Flowmaster
I might as well keep them stock manifolds on, the stock cats,
h pipe and chamber 1.

go for it. I would like to hear.
Just don't be disappointed if your car doesn't sound exactly the same as an LT header car with the same catback setup.
Right now the only options that I'm considering are:
a. Put on the exact setup I want, true duals plus long tubes, and take it off when it comes smog time and than put it back on again. lol I don't want to do that.
b. Same setup except have some custom mid removable mids pipes fab'd up so I can put on the most restrictive cats I can find just for smog and than cat deletes for the rest of the time.
c. Stick to just a cat back set up with long tubes and high flow cats. Which I'll drive around feeling and thinking that it's less than I want it to be, all the time....
also the guy in the vid stated the car only has a lid, ported maf and a tb..stock manifolds and cats still on the car. its pretty loud.

Well while at the local speed shop (Lynn's Speed and Custom) on my 540 build..They just finished a built 402 sbc... on the dyno it made about 503hp with the huge outdoor muffler stacks made for the dyno.. After all was said and done, we tried several mufflers just for to see.. Using the same headers we used a 2.5 pipe about 10' long exiting out the room.. Tried my flowmasters i had, magnaflow and a new Spintech muffler.. Well the flowmaster lost a little under 20 hp, the magnoflow lost about 8 and the Spintech pulled in the same numbers as the HUGE muffler stacks that were designed just for dyno exhaust to be free flowing and somewhat quite.. SO,
I would stay away from Flowmaster if you are concerned about HP.. I think that most hardcore car guys, engine builders and racers all know about Flowmaster.. However, due to thier advertising, the average Joe has no chance..I now run Spintech on the majority of my cars and a Corsa system on my WS6.. Just FYI, not trying to offend anyone, just stating facts..
Also, while I am still being negative, the driver from the fisrt vid SUCKS..unless it was someones wife driving while he was filming.. If that is the best burnout, wheel spin or hot ******* he/she could do, they need to buy a Honda

[/QUOTE]I agree with that LOL. But the FM 10's are a SWEET sounding muffler and I don't think they are very restictive at all. They are a one chamber design IIRC. The 80 series are the ones designed to fit in our OEM exhaust and are three chamber and restrictive once mods have been done....

stock y pipe, to a 40 series flowmaster. it sounds great, and when a little race comes along, it sounds great, but I wanna go with a deeper sound. I prefer flowmaster over magnaflows. they seem to me like an expensive resonator.
