Anyone have a muffler attached right at Y-pipe collector?
I was contemplating putting one of those Dynomax bullit mufflers right where my cat would go (removing it) and taking out my cat back completely. This woul save some rear end weight and give the car a smoother look from behind. Kinda like a lot of mustang owners do. Anyways has anyone ever done this. Would it be to loud inside the car? This would make for a really easy install rather than cutting off the reducer on my cat back and fabing some three inch pipe to connect my headers to the rest of the system.

Heres the one I was thinking about putting in place of the cat.

It'd be kinda loud, and turn downs get loud inside, but, on the other hand you might enjoy it
I can see the pros of this setup: simple, cheap, lightweight, and very agressive sounding. Plus they aren't even real big around, so clearence I don't imagine would be a big problem. If you do it, I'll have to hear about what you think of it. I've always wanted to know what one of those mufflers sounded like as it is.

I may do it and just get a the 14" turndown from dynomax which would dump the exhaust right before the rear axle
hmmmm...so many choices.

I'm tempted to do that and get rid of my aerochamber catback that I haven't even installed yet to tell you the truth

I guess I could try it because the muffler is only like 32 bucks. I have only had my aerochamber cat back on for a little over a year now and I really do love the way it sounds. Plus I spent a lot of money on it. I also invested time to cut the pipes down to accomodate the $170 Borla tips i put on it. But for pure performance in both sound, flow, and wieght the bullit style muffler option seems like the better deal.

Is that basically a glasspack or what? I'm tempted to try this guys, I need an inexpensive exhaust setup to hold me over until I can afford full SLP exhaust. How does SLP y-pipe with the Magnum Race Bullet and 14 inch turndown? I may try this, that's like 250$ all together... not bad... not bad at all.... I'm sure it'd be something not many have heard before
I have them but not installed yet. Here is a link to a video of them on a lt1 with duals, xpipe, and the bullets.

Oh, and here is a thread I started about duals. I posted some pics of the exhaust from the car in the video.

Wow that sounded pretty dirty. Man I am so tempted. If all else fails I can clean it and return it...hehe Plus it is only 30 bucks or so.

OMG, that is *SWEET*! If I just have hooker headers and one of those on the end of the y-pipe, do you think it'll sound all THAT different from that clip?

I am thinking that our's won't sound like that. Number one he has an LT1 pushing 400 plus hp, and number 2 he has a true duel setup with an x-pipe and two of those mufflers. I do think that a single setup like that would sound great and I plan on doing it here in a few weeks.
I dont know, but I believe phil87iroc used one on his setup and really liked it. He had longtubes with the mufflex y pipe, and a bullet muffler. So his would be more similar to yours because it y's into a single exhaust before the bullet but I havent heard his to know if it sounded similar to that or not.

I wouldn't go through with the bullet muffler idea. I dumped my exhaust out of an 80 series Flowsmasher (stock location) and even though it's way behind the axle it still makes my interior pieces rattle like all hell. It makes it sound nice and alot deeper but it's not worth it IMO. Also, you dont want exhaust fumes to have good access to your underbody cause it will eventually rot it out. Exhaust fumes are full of acids and stuff that will eat through the metal!
Plus, inside the car like that you're hearing mostly motor noise, not the exhaust tone. Though I'm sure it sounds great. He's also revving higher than most of us probably do, keep that in mind as well.

What if you were to run an extension and put the muffler right before the rear axle with a turndown? Cuold you spray some protectant and or sound deadening material right where the exhaust would come out?
Sure, you could run it turndown style. Why not? People do it with duals, but they don't have much clearence. But the Bullit Mufflers aren't real big around. You could also even have it behind the axel, I think thats what Guido has. Even with turndowns though, you'll get a lot of interior noise and it will have a resonant sound to it, it won't be as "clear" sounding as pipes out the side or back.

Dumping the exhaust anywhere but outside of the car will make for a very annoying, noisy ride.
Sounds like you already have a good exhaust system from the cat rearward. Rather than toss the baby out with the bath water, fix the restriction that is your cat - either with a 3" high-flow version (if emissions is an issue), or with a piece of pipe.
Excessive rear end weight is not a problem with 3rd gens...

Well I decided just to connect the headers to my cat back afterall. This way I can keep my borla tips which I think helps add a lot to the car and lets people know that its not a v6 RS or just an RS with wheels.

I just installed my SLP headers and my flowmaster catback which I bought from the classifieds still hasn't come and I sent the money out 6/18. Anyway, I figured I would put a dynomax race bullet off the ypipe just to quiet it down on a temp basis. It sounds like quiet open headers at idle and part and WOT are both still really loud. The interior rattles like hell also. My catback better come soon because the muffler off the y isn't practical for a daily driver.

I agree with Plant,
I had TES headers with a 3" bullit muffler to the Y pipe with a turndown. I could hardly tell that there was a muffler on at all. It was a little less harsh sounding, but WAY to loud and annoying. My Edelbrock cat back sounds much much better IMO.

Hg,
I like the way it sounds alot. It has a very airy sound to it under part throttle, not echoey like a Flow though. At idle it is nice and pronounced with each combustion, it doesn't just blen them all together.
Under hard throttle it sounds very racy to me. It is loud, but pleasent, and sounds muscular.
It drones a little on the highway at 2500 rpms, but not much more than the Flow on my '92 does.
I like it because not too many people seem to run the system, and it truly has a unique sound.
I will try to put up some files of it in action soon.

Excuse me if I am misunderstood but if you put an exhaust thats to big on dont you loose torque (as a result of less backpressure)? Wouldnt taking it off to this extent kill torque or would the bullit offer enough BP? I had my 3 inch catback fall off behind the cats last fall and had to drive it home with nothing passed the cats (cat back tied up). Torque was gone completely and it felt like a 4 banger when i went to pass.

G-tech time of my car with the dynomax race bullet right off the ypipe is 14.43, track time of 14.53. G-tech time with full 3in exhaust is 14.6x and I have yet to go to the track with exhaust. It does feel like it pulls harder with full exhaust but the gtech ain't sayin so.
im guessing the reason why the catback feels like it pulls harder because you are losing torque without it. the exhaust is too free flowing. but with the loss in torque you have a gain in hp hence the faster times. but the less torque the less sotp feeling you get. im probably wrong but i think im on the right track.
