I'm very happy with my custom Pypes setup. I just bought the mufflers that come with the system and put larger tips on. Sounds like Pypes for half the cost.

It seems like a lot of people are taking that route. I'll admit that it does sound pretty damn good. I want to replace the stock 2.25 with 2.5 tho as I plan on getting LTs.

The shop I went to was willing to upgrade my piping to 2.5" for $75 more. But I decided not to do it in case I didn't like it and ended up needing to buy a full system to replace it. Needless to say I should have probably done the full upgrade since I really like how it sounds and performs for the little bit I spent.

They also have aluminized steel, but he already knew I wasn't interested in that. I'm not sure if it would have brought the cost down.

Maybe I'll just grab some M80s and see if I can have some 304 stainless bent

Busted! Sorry for not responding to this thread, been occupied with R&D on some new products.

Yes, our chambered exhaust does offer a great muscle car sound. Our design was created to give the V6 Mustang a deep growl while decreasing backpressure using a free flow design muffler and smooth mandrel bends. If we chose a full 3", there would be a noticeable loss of TQ/HP on the bottom end. Using a 2.5" exhaust has allowed us to create a system that produces power across the entire RPM range. This means an increase in throttle response off the line, while still having a enough free flow at higher RPM to make better horsepower than stock and still support additional future engine modifications. You can expect 5-10hp with a catback exhaust upgrade. Our design will gain horsepower but its actually based on other variables. Keep in mind the motor is a huge airpump, the more you inhale/exhale the more power available. Now if you add in a larger capacity intake, re-tweek the computer to compensate for now modified air fuel ratio, then you have a noticeable difference in power. (I'm sure you guys all know this, just trying to get my point across). Now if you want to make power, buying a catback is only a small part of the equation, but this is what makes the sound you want. Great first upgrade because now your car will sound sweet!!! One of the best upgrades to increase power on any vehicle is to get rid of stock manifolds and replace them with a long tube design (28-32" primary) because this will increase power from idle to redline.

So in short its all relative.

Purchase a catback based on sound, quality of material, fitment and of course price.

I can understand the loss of power if your overall volume of exhaust is too small for the dynamic of your motor (ie supercharger, bore/stroke, rpm requirements, etc...) If your V6 is pushing over 500hp, then you want to consider a larger exhaust, no doubt!

Ok now let me have it, I know you guys will!! haha

Paul,

How about offering the retro chamber mufflers as a bolt on to the stock pipes? I'm one of the potential buyers out there that isn't interested in making 400 hp with my V6 and I'm not interested in paying $500+ for an exhaust mod.
Make up a pair of mufflers competitive in price with Flowmaster and Dynomax and I'm in.

Barring that, make the mufflers and resonators from your cat back system available separately at a reasonable price and I'll handle the install. $154 for the 2" mill finish retro chambered muffler is kinda steep when compared to the stainless offerings from Dynomax or Flowmaster. I'd suggest $259 for all four would be worthwhile, just in case SW hasn't noticed that inflation has been checked by demand a few times lately.
