Magnaflows would be my choice. They are tolerable at low RPMs and cruising. You open them up and they are loud. They also have a large selection of custom styles and sizes. They are a good design that doesn't restrict flow or power.

Magnaflows:

I want something that wont drone on the freeway but sounds evil at idle and when I step on it. I had B&B bullets on my vette and they droned like crazy. Couldnt take the car on long trips and couldnt hear the radio over the drone.

Do the Spintechs drone?

My experience with Magnaflows is on C5 vettes and LS1 camaros. It's been a few years but I don't remember them droning. The Camaro only had a 228/232 cam with full exhaust so it was flowing some air. It was not quiet while cruising like say a Corsa system. It was definitely there but not annoying.

Speaking of Corsa, they have a db line of mufflers that are universal like Magnaflow and others. I honestly haven't heard them but Corsa only has quality products. Might be worth checking out in case you like the sound.

I like to Borlas. All the DSE cars run Borla and after seeing them at the GG autocross events and the OUSCI this year I had to give them a shot.

I personally don't think you're gonna find something that meets all your goals here.

Dumps before axle
No droning
Evil at idle

I think you'll be making some sacrifices, but like a lot of things, evil, quiet, and other descriptors are in the eyes of the beholder.

Personal preference, but this is one of the cleanest sounding motors I've heard that works for track and street. You just need to imagine it with an insulated interior and a "normal" sounding gear box. :D



I believe Brian is running 3" Borla's that side exit in front of the left rear wheel opening. Check his build thread it shows the system.

Exactly, your first problem is dumps. Sound reflects... Regardless of the muffler you will have some resonance.

umm .... HALF the great sounds emanating from that car are from said transmission. :thumbsup:

Let's just say Brian's car is high on my all-time favorites list and straight cut gears rock! :thumbsup:
