Curious how the borla catback would compare?
Thats what I'm lookin to get. Not sure what to do with the midpipe situation yet. Anyone here know any good midpipes to use with the borla? Does it matter or change the sound alot? Thanks

Why do you lose?
If you improved the intake, and the exhaust, how could you possibly lose HP or TQ?
I would think you would stand to gain in both areas?

So does the computer adjust?
So having changed this, wouldn't the computer adjust accordingly over time?
Do you have to tune, or get a chip to compensate?

Definately an interesting and much appreciated review. Right now my mach 1 is stock except for 2 1/2 inch Vortech mufflers welded in w/3 inch chrome tips. The Vortech's are less expensive, and supposedly flow better than and sound the same as flowmasters. Everybody that has heard them so far says they do. My car is somewhat quiet, but has a mean exhaust note. I'm considering right now leaving the mufflers and rear end exhaust plumbing stock, and hooking it up to shorty headers mated up to an MRT catted H-pipe. Then I would add electronic exhaust cut=outs directly after the cats. That way I could be somewhat quiet when I wanted, keep the backpressure, and then go absurdly loud when I wanted to also. Anybody have any feedback on this particular setup I'm thinking about??/
-Thanks -Dan

Tach 9,
Thanks for the feedback. I know I could get a mean exhaust note with a good catback. I'm just thinking it would be cool if I had both a quiet exhaust and loud on the car. If I get a loud catback its always loud. But if I leave my vortechs on, it stays somewhat quiet when I want it to, then screams when the cutouts are open. -Dan

To all inquires,
I thought the exhaust review was great for all manufactures involved, However i must say i thought the subjectives notes inregaurds to SLP's loudness was highly exagerated. The SLP loudmouth cat back system, in my opinion was not too loud and i disagree that you could be heard from 10 blocks away. Maybe 2 or 3 blocks, but not 10. The installation was like what they said. I have the SLP loudmouth cat back system on my Mach1 and the installation took me 45 minutes on a hoist. It might take as much as a 1 1/2 for others but the installation was a piece of cake and probably the easiest exhaust cat back system i have ever installed and everything fit perfectly. At this point i wouldnt hesitate to recomend them to anyone that want an awsome sound. SLP has a tone all their own and thats what sets them apart from all other exhaust systems. Also note, i would go a little louder by getting rid of the cats and use a offroad H-pipe or X-pipe in place of cats. Dont waste your time with the catted pipes doods and you'll save yourself some money too. And though you many void your emission warranty at least you wont have cats to plug up your exhaust system or rob your engine of the power it truely makes. Its your choice. Thats my 2 cents. |

Cat-back exhaust
DanK, thanks for the prompt reply. What is exactly is a cat-back exhaust? As I read the Mach 1 review of the three exhaust types tested, they looked like much more than a muffler. Which system do you like for power w/o too much noise?

A cat back system generaly is everything from the catalyst toward the rear of the car. Which include mufflers, tailpipes, and tips. Some systems have the mufflers welded onto the rest of the tail pipes making it a two piece system. SLP makes their system in 3 pieces which makes installation a piece of cake. Some systems have mid inlet pipes, mufflers, talipipes, and tips. Depends on what system you want to use. This gerneraly is how a cat back system is defined.

The exhuast sounds like the car is running under water when brand new but don't be alarmed. The exhaust will sound better (sweet) after a few hundred miles of break-in time. The sound is awesome but not overpowering with the stock H-pipe. Good luck with whatever you choose. :THUMBSUP:

Nice link
The testers remarked that the tone quality was very pleasant and gave the Mach 1 an authoritative note without an ear shattering loudness.
Everyone who's heard my car with the 'Flows on likes them. A couple of buddies who really aren't too high on the Mach loved the sound of the Flows. They aren't enough for a lot of people, but they are plenty loud for me. That write up claiming a 12rwhp/8rwt gain from the Flows is consistent with my seat of the pants assesement. The car just seems to run a little stronger. The change in the A/F ratio's may explain why it seemed to run better with the Flows after I disconnected the battery to reset the computer. |

cat-back
Thanks for the detailed info. One more question. Why not just get a muffler, why change out so much of the piping under the car? Isn't the muffler what makes all the difference?
