If you've had MULTIPLE EXAUST SYSTEMS.....
I have the Grot offroad 3" y-pipe. Should I start by putting in a FM collector? Is there anything to be gained?
I'm leaning towards the SLP20TL or Loudmouth exausts that can be easily removed at the track. How do they compare to the Mufflex 4". Your thoughts and recommendations are greatly appreciated. I know some of you have been exposed to before/after dynoes with different exausts.... how well do the above exausts flow and will I lose anything by going back to the 3"?
I'm actually considering putting the RT back on whenever I do headers to calm the sound down a little bit.
Buy a dynomax mandrel bent intermediate pipe for a 93-95 F-bod.
Weld in a 3 inch cutout
Weld on a 18 inch dynomax race magnum muffler
Buy a 90 degree mandrel bent 3 inch pipe to use as a tailpipe and then use a chromed slashed tip.
VERY light, and very high flowing.
I ran 126mph in the 1/4 through this full exhaust with MAC headers and MAC 2.5 inch Ypipe. The int pipe and muffler/tailpipe came in under 150 installed <img src="gr_grin.gif" border="0">

Don't you think that would be extremely loud as well. With this stall and 4.10's, I've got to quiet it down. I can't drive 1100 miles to AZ next week the way it is. I would either fall asleep from the drone, or not be able to talk to my brother when I got there. <img src="gr_stretch.gif" border="0">
dual cutouts after the headers, stock Ipipe, dynomax super turbo muffler. It's as quiet as stock, and flows much better. At the track we all run open exhaust anyway so who cares?
I have the Mufflex 4" too, adn theres no way Im going to drive around my neighbor hood with it. Concensus is that there are 3" systems that work just as well on H/C cars. The systems I am considering are:
Corsa stainless or
SLP Dual-Dual
Both are stainless (its just MOIST up here, even if you dont drive the car in the rain), and both are quiet. If you remove the "cone of silence" from the SLP, its supposedly a bit louder and flows really well. The Corsa is supposed to be very nice, but on the Vette I thought Corsa'a made the cars sound like boats. Makes sense since Corsa's main business in Marine exhausts <img src="gr_stretch.gif" border="0">
Im going to put in the 2x 3" into a 1 4" Y pipe using the flowmaster D port collector, and there will be 2 Dynomax Bullets, one on each side of the Y. If this makes is drone less, I *might* (super might) keep the Mufflex, since the car is for little more than summer driving and Road Racing. I need the money for Brakes anyways.

You should know ever since I ran the offroad y-pipe without an exaust, that I need a little more sound than stock. <img src="gr_images/icons/wink.gif" border="0">
I want to sound good on the street as well, but be able to get the weight off at the track to whip ya. <img src="gr_grin.gif" border="0">
I got an error trying to open the pictures. Hmmm.... the "hooker" may be an option worth looking into. <img src="gr_stretch.gif" border="0">
Anyways, I'm not interested in a dual exaust because 1) it would have to exit out the rear of the car or it'll resonate too much, and 2) if the dual did exit the rear, it would be too heavy and just a pain in the butt to work around. I don't see any HP to be gained by duals, just noise or weight.
Amen to that. For the price, there isn't a catback that holds a candle to the Hooker system. IMO, there isn't many catbacks that can hold a candle period. This exhaust is under 300 bucks, flows better than 99% of all other systems for the f-body, and is the best sounding catback I have ever heard without cats on an LS1. I have gotten probably 50 compliments in Atlanta saying that my car was the best sounding LS1 they'd ever heard(Mac, offroad, and Hooker). Not only does it sound great, it does NOT drone at highway speeds, and is very mellow around town. Nice deep growl, and when you floor it......simply musical viagra <img src="gr_images/icons/wink.gif" border="0"> <img src="gr_grin.gif" border="0">

I had the mufflex 4" before, and I can say that my mufflex WITH cats is much louder than this setup WITHOUT cats.
My car can barely be heard idling in a gas station (and I currently don't have cats!).
For the cheap systems, the Hooker sound very good and flows well. I cannot endorse it, however, as the construction quality is lacking - on my old one, the tips and muffler were rusted within a year, one of the exhaust pipes was misbent, and the U-pipe was rubbing against the heat shield no matter what I did with it. The system looks like a$$ also, but you can fix that a little bit if you put your own tips on there.
Chris ARE 360 and Terry Burger have some good exhaust ideas here. Do not know how they flow, but they are reporting good results.
Visceral: There ain't no way the Corsa sounds like a boat with the setup I have. People are raving over how my car sounds with it (I love it also). However, Corsas sound very different on F-bodies than they do on Vettes - has to do with the dual-exhaust x-pipe resonation on Vettes.
Jantzer - I would try some of the ideas above. If you have the dough, I would recommend a Corsa (for medium loud) or an SLP dual/dual (for quiet). Otherwise, I would try the custom setups mentioned above. The Hooker would sound/flow well and be cheap, but be aware of its quality and appearance issues.

Do a cut/paste for the pics. Geoshitties sucks.

The drone from the Mufflex IMO is specific to a 4" catback. I cannot get it to go away. I swapped off my Flow 4" and put on Dynomax like the one in Mgreen's pic and it's the same. But I can't beat how my exhaust flows...sigh
I think the dual/dual is the ticket to be old man quiet.
I think that the RT, Hooker, etc are all loud and but will not drone.
Triflo sounds very classy.
I currently run TTS longtubes, 3" custom ORP, and 4" mufflex with dynomax ultra flow welded muffler.

You're running about the same combo I am, do you ever take your car on long trips, or is it a racecar? <img src="gr_stretch.gif" border="0"> Some people around my neighborhood think I'm doing 200MPH up the hill by my house when I'm doing the speed limit. It makes me wanna get out and slap them for being stupid and then slap myself for not being able to talk to the girl next to me. <img src="gr_grin.gif" border="0"> Do you think the 3.5" Mufflex w/Spintech would be considerably quieter?
I'm thinking the SLP20TL will be the best for fit/finish/sound/price/durability. I think I might as well pay a little more than the Hooker and get a stainless system.
Does anybody know how much any of these exausts weigh?
That could also be a deciding factor.
