400 hp
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

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.

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

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.

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.
