Another User, if you like the Dynomax better, then that's good for you! And it very well may be worth a few more horsepower. I just don't feel it necessary or practical in my situation to spend the money for another cat-back just because it may free up a few more hp, especially given how much I like the sound of the Flowmaster.
And I said I wasn't going to get into the "Flowmaster Sucks" argument

its been proven time and time again flowmaster is a restrictive exhaust.
asp crank pulley and belt, and a cutout should net you your 400 ponies. yet every car is different.
I had a 224/228 cam and iw as in the same boat as you. i made 380 rwhp with the ls1 intake. i upped the stakes and went with a bigger cam (232/232 fromc omp cams) and sold the 224/228 and i ended up making money off the cam swap (i gotta great deal on the 232/232 and i gotta sweet offer on the 224/228) you could get a good chunk of change for that 224 and go a bit bigger most likely. but with teh power you've already made with a flowmaster catback i seriously believe with a pulley and cutout you'd hit your mark.
best of luck to you.

thanks for all your help guys, i think i will go ahead, and get me the cutout, asp pully, and slp loudmouth, and be done with it, maybe get dyno tuned again to see what i get, and thats it. i think i will be at or very close to the 400 hp mark. since this is my everyday driver, i realy dont want a bigger cam, or head work, i already have a 95z with a LT4 396 that i have for my project, and mustang killing. i will let you all know if i get the numbers.

Chris 77, good luck in the quest for 400hp. Sounds like a pulley and a cutout will get you there.

All I'm saying is that a) I love the way Flowmaster sounds, and b) it's not worth it to me to spend the extra money to buy another catback just to free up some extra hp. That is my opinion.

Seriously, how much hp do you think I would add by just switching out my muffler? I'm doubting it's going to be more than 6-8, but I've been wrong before.

get an underdrive crank pulley, get rid of the flowmaster, and take a look at this link .

If you like that chambered sound you can get a hooker aerochamber muffler. still has that throaty sound to it and they are less $$ than the flowmaster muffler. they do sound quiet inside the car but make no mistake, they boom out the back. I had contemplated going to a flowmaster muffler with my car after i got the hooker cause i *thought* itw asn't loud enough till i let my dad drive the car infront of me. it sounds sick. and HOoker has a very sweet chambered design. I only picked up 4 rwhp with a cut out over it.
However each car is different. you may only see a 6-8 hp difference swaping out your flowdisaster. then again you could see as much as 10-15. If you are NOT stock internally, you WILL most definately see a nice gain over the flowmaster catback though. hands down.
hopefully that helps ya some. i think youc an get the hooker muffler for around 80 bucks. but a whole catback you can get for around 300 shipped.

If you are getting cutouts, spend the cat back $ on new rocker arms. Those 2 mods will get you to 400. And I saw NO gains from an ASP pulley. All I got was a 5* hotter engine. Not to mention the old ones don't fit with double roller chains, so if you get one, but a NEW one. Don't buy one used, or you may be sorry.
