Re: Insert Your Exhaust Sound Clips Here
 

The x-pipe without cats is LOUD(it scares people!) but interior resonance is better than with cats. The x-pipe with cats had the most resonance and was still louder than the catted h-pipe.

The h-pipe w/cats was great for someone who wanted a nice sound without the resonance and not too loud. The torque was better down low with the h-pipe but it didn't seem to flow that great on the top end. This was the best set-up for interior noise.

Hope this helps :3amin:

Re: Insert Your Exhaust Sound Clips Here
 

Yes, that helped out a lot actually. Thanks for responding so quickly.

My personal taste was the H pipe and from the sounds of it, I'd like the interior noise of the H pipe better as well. What brand off road H pipe was that on your car in the test?

Re: Insert Your Exhaust Sound Clips Here
 

It was actually a catted h-pipe by Mac.

Re: Insert Your Exhaust Sound Clips Here
 

I want those 44's. I just wish I could weld them into my Magnapack catback and call it a day but it doesn't work like that because of the different in/out offsets and junk.

Re: Insert Your Exhaust Sound Clips Here
 

Hmmmm, interesting. Do you think an o/r h-pipe would sound similar?

Re: Insert Your Exhaust Sound Clips Here
 

Similar to the catted h-pipe? It should but just much louder. I haven't seen many o/r h-pipes with flows on this site. Most of the o/r h-pipes I've seen here are combined with straight through mufflers. I know there is someome on here with o/r h and super 44's. I've been wanting to hear it but haven't seen a sound clip of it yet.

Re: Insert Your Exhaust Sound Clips Here
 

Do you think welding Super 44's will work on the magnaflow cat back? (not the packs)

Re: Insert Your Exhaust Sound Clips Here
 

I think so because the Magnaflows are offset/offset in/out or whatever and so are the Flowmasters

Re: Insert Your Exhaust Sound Clips Here
 

I don't see why not. The magnaflows should be offset just like the stock mufflers.

I'm too slow

Re: Insert Your Exhaust Sound Clips Here
 

Thanks guys. I have been wanting to order a pair.:3:

Re: Insert Your Exhaust Sound Clips Here
 

Both sounds great! Though you're Packs sound way different then mine. I wonder if it's because yours are welded into the stock catback or something.

Interesting!

Re: Insert Your Exhaust Sound Clips Here
 

IDK. Mine are bigger than what comes on the actual cat back. They may have something to with it. I had to get them bigger so they would fit the stock exhaust.

Re: Insert Your Exhaust Sound Clips Here
 

Maybe that's why they sound deeper than mine.
Sounds great none the less!

Re: Insert Your Exhaust Sound Clips Here
 

It's probably the x-pipe design. Bassani seems to have a design similar to BBK where the "X" is almost like a chamber instead of 2 pipes just running together like Pypes, UPR, VRS etc. Maybe that changes the sound.

Re: Insert Your Exhaust Sound Clips Here
 

You hear the way those 2 chambers pop and crackle on deceleration? Super 44's don't do that. At least on my set-up they don't. There's a little bit of that crackling sound but nowwhere near as much as the 2 chamber super 40's. I kinda wish they did.

Re: Insert Your Exhaust Sound Clips Here
 

OK, Here's a sound clip you might not heard before: Its a stock Mach1 with the stock exhaust, minus the h pipe, I removed H pipe and installed a Bassani Xpipe with cats, Manifolds and catback are original. I believe it sounds great, tell me what you think,

Re: Insert Your Exhaust Sound Clips Here
 

Cool, thanks. What really is the difference between the aluminized steel and stainless steel versions of the MAC catback? Is one more durable or sound better?

Re: Insert Your Exhaust Sound Clips Here
 

Stainless "never rusts"
Alumized does rust

Sound is no different though sir! I had the stainless and liked it.

Re: Insert Your Exhaust Sound Clips Here
 

Thanks dude! Now I just gotta decide what midpipe and catback to get. :??:
... and pay someone to install it cause I lack car skills...

Also, which cat back system do i need:

TK8604 96-04 4.6 GT 96-98 Cobra 2.5" w 3.5" tips
or
TK8904 99-04 Cobra 2.5" with 3.5" Tips

And the stainless one is somewhat hard to find!

Re: Insert Your Exhaust Sound Clips Here
 

The cobra one is made for an IRS so that wont work. We use the same cat back as the GT's.

Re: Insert Your Exhaust Sound Clips Here
 

The one for the 99-04 Cobra will just be for the 03-04 Cobras because they have the IRS which forces the catback piping to be angled differently. Any time you want a catback get it for the 99-04 GT like the TK8604.
