I just recived my new Flowmaster Super 44's so I'm off to the exhaust shop early next week.. My question is, should I have an x-pipe, h-pipe or no crossover pipe installed at all? I'm currently running Headman long headers with large lopey cam and loudness is not a concern but I'm wondering about the sound out the rear.. If I dont install any type of crossover pipe, the rear pipes will individually bark for each lope so does that mean they will pretty much eaqualize and spit out notes at the same time with some type of cross over? Which way will sound meaner? I just want this thing to sound totally wicked and not worried about a mild perfromance loss due to not having a crossover so I dont know which way will sound better...

I called Flowmaster and they said ideally you want the mufflers under the body and between 18"-30" from the headers for the best sound but I dont think they will fit under the body. By the way, I'm going with 2-1/2" all the way back..

What are your thoughts?

Sound is so subjective that nobody can tell you what you will like best.
You might try searching for videos on YouTube or Streetfire to help you to form an opinion.

I had a dual 2 1/2" system with 3" Flowmaster 50s with a crossover. The drone and resonance and volume were all too much. I was going to switch to Magnaflows, but I tried the x-pipe first. That took care of everything. It's not nearly as loud and the drone is gone. It's easy to add a x-pipe later, so try your sysem without. If you are happy, your good to go. If not, add the x-pipe. I have both the x-pipe and cross over. Check out this thread: http://forums.corvetteforum.com/c3-t...ifference.html

Wow, thats a nice shot of the underside, I never seen both a H and cross in the same system, thanks!!

I think that would be a good idea and something I didnt even think of so I will go without anything at first and then have one or the other or possibly even both installed like you did if I dont like it.

Thanks again!!

Here's a sound clip of my car. 2-1/2" aluminized exhaust with Flowmaster40, no X or H pipe, HookerComp Headers idling at aboot 700rpm.

Does aluminum give off a different tone? Sounds nice!

Here's mine with just the Flowmasters bolted to the end of the header....

I just love hearing a good set of duals, I have the 2 1/2 inch Magnaflows with the H pipe and running the late model engine. It's like blocking the heat riszers on the old Chevy, a blurting sound. I turn off the radio and roll down the windows, It's like being in Heaven, Course I will never see that. LOL Thanks for the sound show. Gene

I would say that both would be similar, though not identical from a power standpoint. Go with whatever fits in easiest closest to the headers. In my case, I have mandral-bent, 2-1/2" exhaust with a 2" H-pipe and Dyno Max UltraFlo stainless mufflers and it sounds great.

x pipe all the way !!!

I got my Dr Gas X-Pipe under the differential. 2 1/2" System with dynomax headers. Even with the X the flows droned like dog's. Switched the mufflers out to magnaflows and now it sounds pretty sweet.

As far as your exact question, I never heard my new system without the X-pipe. I see you point on hearing lope async on each side...also with separation you can tell which side is smoking, rich etc...

I would agree that if your in question, start out with straight duals. If you don't like it, then try the X.

my car currently sounds and runs much better than it looks! hahaha but hopefully that will change this next winter!?

I got tired of my chambered exhaust after about a year and went with an x-pipe and Dynomax super turbos. What a difference on my old ears. I bought the x-pipe from Summit and had the local muffler shop run everthing back from my Hedmans

I have an X pipe and 2.5" pipes with Magnaflow mufflers that I am pretty happy with. It is Mags system and can be found on planetmagnaflow.com.

Hey Eddie,

Did you put the magnaflow kit on yourself? If so how well did it go together? Did everything fit well?

Thanks

Only thing that will kill the drone is putting a quiet muffler on.
Threw the Dronemasters in the trash and bought some cheapie Hooker super comp turbos, 0 drone anwhere, night and day.

Want it even quieter now, mving to a large case Dynomax hemi super turbo set. Even less noise and outflow the hookers

I put the kit on at the house. Me and my son did it right there in the garage. If you look close the car is still on jack stands. I have headers and the kit was designed with stock manifolds in mind. So, I did have to take the car down and have some work done by the shop to connect the headers to what would have been the down pipe. I am happy with the fit and the sound.

Here is a couple of short videos of the car, untuned but you can get an idea of how it sounds. Keep in mind the motor is an LS and has a different firing order.

I talked to a Flowmaster rep at SEMA and he recommended the x-pipe. So I went with the H and it sounds great. Do whatever fits the best.

Long tube headers with X and resonators toned down my Edelbrock RPMs without restricting flow.

I originally fitted a 2.5" twin system with an X-pipe and low restriction mufflers.... it certainly felt quick, but sounded like a late model LS1 and it droned from 1200 through to 2200 rpm .... terrible. I didn't like it.

I then had a new system fitted ....2.5" twin system with super turbo mufflers... no balance pipe.

I only have a touch of resonance at 1200 to 1250 rpm, but that's easily avoided.

Here's some vid clips.

That sounds really nice! Sounds almost like a mild top fuel dragster.. What brand mufflers are those? I'm starting to think its going to give a much better rap out the exhaust tips with no balance pipe at all.

If you watch the bottom video, there is a bug that starts walking across the driveway and then you blew it about 2 feet backwards when you rapped on it, lol
