Hi Everyone I have a 2007 SS monte carlo and I was thinking of getting a Magnaflow exhaust cat back. I wanted to know if anyone here has one and are you happy with it?

Also do you loose any torque?

I really don't know if I should bother with it, if it doesn't make a difference in sound or preformance over the OEM. Please let me know what your thoughts are.


Thanks
Tony

 

I really want the Magnaflow cat-back as well. I suggest that you take a peek at the forum below. It is dedicated to our engine and has a lot more performance information.

i have a magnaflow on mine...but mines a 2002 ls with a 3.4 so idk if this will help, but i noticed a definite change in performance and gas mileage.

 

Ok I just bought and installed the Magnaflow cat-back exhaust system. In one word WOW.
It sounds 1000 times better than the stock system, and I can definitely feel the power at the higher RPMs. It has a really nice deep bass sound to it. Now it sounds like it really does have 300+HP under the hood.

I should have done this last year, If you haven't got one yet DO IT, you won't regret it trust me. When I started it up and heard the new exhaust I was very very surprised at just how good it sounded.

Love it.

 

Here is a picture of it.

Congrats. It looks GREAT! Get a sound clip up and post on YouTube or something.

I actually decided to go the cheaper route and get two Flowmaster Super 40 mufflers installed. With Flowmaster tips it should be around $225 shipped.

This is how she should sound...

Do not get me wrong, this is a great forum... But there is absolutely NO love for the 5.3 guys over here it seems. I just had to put that out there! lol

Thanks I really do love the new exhaust system.

That sound clip sounds great, are you going to keep the resonator or replace it with a pipe? $225 ships is a good price.

I'll post some more pics too.

Hey Rick Once you get it in you will be driving around with the radio off just to hear that awesome sound. Good luck

 

here are some more pics..
