awesome! this means the nameless axleback + factory midpipe combo is 9lbs lighter than perrin's catback.

perrin catback = 39.5lbs
nameless axle back (18lbs) + factory midpipe (12.4lbs) = 30.4lbs
100% factory: factory midpipe (12.4lbs) + factory axle back (25lbs) = 37.4lbs

I think you can't go wrong with either. It's more a matter of taste and want; both systems look great. It just depends what are you looking for. :thumbup:

I would wait to compare at least until Perrin releases their exhaust parts forward of the catback. Ideally I would wait until each company has a full exhaust solution for sale, including header options.
And then I would wait some more to see independent dynos. But that's a lot of waiting!

The entire factory exhaust weighs about 38.6lbs with as someone else showed about 12.4lbs of that being the midpipe. So the stock axleback weighs around 26lbs. The Nameless axleback is around 16lbs, so it shaves around 10lbs of weight off of the stock exhaust. I think it weighs a little less if you go with their smaller mufflers.

When I spoke with Nameless they said their re-designed midpipe with a resonator ended up weighing more than the stock midpipe and made negligible power so they felt it wasn't worth selling, it would just add weight and cost people more money.

Perrin's complete catback weighs more than the stock one, unless you get the option with no resonator. The catback without a resonator weighs 26lbs total, so about 12.4lbs less than stock. But then you have to deal with a louder and probably raspier exhaust.

As for dyno numbers, this is what Perrin got out of their true catback, with the resonated exhaust. When they dyno'd the car with just a straight pipe after the stock midpipe, it made around 3WHP. This is how they showed replacing the stock midpipe definitely had an effect on performance, at least in their testing:

I can't seem to find any numbers from Nameless with just their axleback, I think it made around 3WHP.

I'm going to probably buy the Perrin without the resonator and then have the car dyno tested without it and then with it just for my own piece of mind.

well a tune would fix all this comparison. I think any exhaust with a tune will have good results regardless the brand

I bought the Accelerated Performance Catback myself. I'm fairly certain I remember him hinting it'd be compatible with another product he was developing. I imagine he was referring to the Turbo Kit. Have you looked at the Accelerated Performance Catback? I bought one myself and enjoy both the look and sound of it.

No spaghetti for me.

I'm not sure how the OP can expect a proper response to his question given that neither Nameless or Perrin have released their products.

^ this... BUT you can tune the stock exhaust for a phat gain as well. All cars ship with a conservative tune to be driven anywhere under any condition.

I'm pretty sure both are available

nameless definitely is.

I ordered the Perrin Catback last week.

Houston calling Captain Snooze!!! Captain Snooze do you copy me???


Nameless has been available I believe for about a month. Perrin's catback has been available for abou three days. Its very easy to see that, even in this thread...
