I don't know.. It sounds really nice at WOT, but it's not like you'll be driving that way all the time. The second clip nearly pops my headphones. I can't imagine how it was in person. It had to be crazy loud as the video started shaking!!

Did you get your dyno result file yet?

 

Hard to say from a YouTube video, but it sounds pretty good to me. What's wrong at 3-4k? Does it drone?

 

Yeah it was super super loud, at 3-4k it drones loud but I remember when I installed the tubi it took a while to settle and then the noice was much more refined so that's what I'm going to try. If it doesn't work I'll see what I have to do.

 

Hope this helps give a persective - PC sound clips just don't give the full story.
I have the RSC ECU tune (also tried AM Power kit), RSC Green Filters (also tried K&N), drilled air boxes (also tried the AM Power kit boxes), RSC 200 cell cats, and tried all the RSC exhausts w/ 200 cell cats. Also have RSC springs (tried H&R Coupe springs), and the AM cabrio rear sway bar (larger than AM coupe). I like a bit of sound - probably more than most - decided on the more quiet RSC exhaust w/ these open cats combo. The full on open exhaust and 200 cell cats was louder than any non-street race car ! With my RSC combo I have no drone, anywhere in the rev range, any gear. Car pulls much stronger then stock (2007, 4.3) esp. up the rev range. The car has some serious sound but have also spent 9 hrs. on road trips w/ wife in the car - in other words no ear buzz after being in the car a long time (vs 1.5 Hrs at a concert!). I believe this combo produces more power than a stock 4.7 - but do not have dyno curves to comp. Then again curves vs. actual running on the street & pulling thru curves can often be different too.

 

Michael is right, I don't care about the dyno specially where I live is hard to compare with others. What I do know is that the car is defenately faster and way louder.

Most likely I will go your way replacing the tubi with the quiet RSC.

 

Yeah, I thought the same thing. The car seems more eager with the cats. I dynoed my V8 with the sport cats and RSC tune (OEM exhaust) and saw an approx. 25-30 rwhp increase.

 

RacerX, how was the sound in your V8 with the factory exhaust?? Was it unbearingly loud, and did you have any drone?

 

I liked the sound a lot and kind of miss it now. It was significantly louder than stock, but was not too loud IMO and didn't drone. Honestly, what I liked least about the sound was that the car wasn't as fast as it sounded. I have since remedied that problem.

 

Do you guys think that the cats and the RSC quiet exhaust is a nice combo? Better than stock muffler with cats?

 

I honestly love the RSC Cats and Exhaust combo (I have the Sport version) ... You'll definately hear it from far away when you put the foot down, but there is also no drone when cruising. To me, that's the best of both worlds. Some people probably would say that it's too loud, but I just think of it as beautiful AM music. I have heard that the Touring version coupled with the Cats is a solid combo though; not too loud and you get the same added performance. In the end, it all depends on what you're comfortable with, but I say go with the Sport version!!

 

I'm sure that isn't a problem now!

 

I think i missinterpreted myself by saying it drones, actualy the noise that comes at certain RPM's is more like a new note that i wasnt used to.

Today im going to have a friend drive my car to see if i like the sound from the outside.

I dont know but by what you said, i think the way the tubi sounds with the cats is simillar to the one you have.

 

Everyone talks about an aftermarket exhaust & cats combo. What about using the 200 cell RSC cats with the factory AM exhaust? Has anyone done that? I'm curious what this would sound like.

 

Just adding my two pennies but has anyone done a custom exhaust setup? I had a custom 3 inch pipe mandrel bent straight through from the cat back. The sound is pure aural sex.

 

I have the RSC 200 cell cats and factory exhaust and it sounds great! It takes a little while to get used to a louder exhaust note but I would never go back to stock. I would think that the RSC touring exhaust should refine the sound a bit but very happy with my current setup! My favorite part about 200 cats...driving through tunnels.
