How Much Power Will This Flow? Does Anybody Have Any #s With This Exhaust? 2001 WS6 WITH D1SC

 

I believe that Magnaflow picked up 13 rwhp and 17 rwtq on the dyno when they tested it. Pretty much one of the best-flowing catbacks on the market and has a great rumble. If you've got the D1SC, you may pick up even more.

 

I concur.

 

That's because great minds think alike.

 

Well that depends. I've spoken to Magnaflow and they won't issue any flow data for their mufflers. They say because of the lack of industry standards, which I think is pretty fair cop.

I would have thought the catback they offer must be pretty good, but with a supercharger you are well exceeding the capability of a normal engine.

Any idea how much power the engine is producing?

An alternative idea would be to buy something like a Loudmouth and swap in a Magnaflow bullitt muffler. Magnaflow recommended part number 14619

This is a 14" long muffler 6" diameter and 3" inlet/outlet. It should flow well enough to be a minimal restriction on a 500bhp motor, this would place it at being as good and probably better than most off the shelf catbacks. It would be LOUD though. They also offer the same muffler in a 4" diamter which will be louder still.

The biggest problem you really face is the tubing @ 3" is the main restriction on the level of BHP your engine is likely to be producing. If you plan on 600+bhp from the motor then a consideration of 3.5" or even 4" tubing should be considered for the best results.

A 2.5" dual system would be an alternative and about equal in flow to a 3.5" Y pipe. But dual setups have other issues so REASEARCH before deciding.

Personally if you have a bolt on 7psi blower car with ~460-500rwhp I'd go for a custom exhaust, as it will give you the most benefit. Something like the Magnamouth above would get my vote.

Else you'll need to upgrade your Y pipe also.

Alternative idea would be:

3.5 Y pipe, with a good Y Merge collector into a single race style bullett muffler (Magnaflow offer a 3.5 inlet/outlet race muffler, but it costs). 3.5" over the axel spliting using a reverse Y into either 3" or 2.5" pipe and exiting on each side of the car.

 

thanks im gonna rethink this i bought a hooker offroad y and magnaflow catback but when i looked into the muffler it looks very restrictive like 2.5 inch inside prbably to restrictive

 

We've made a lot of power with both the Hooker and the Magnaflow cat backs, I really don't think it's going to hurt you much. Bob

 

The magnaflow catback in question has shown to make power over stock in FI cars as well as NA.

Here is a 2001 Camaro SS stock and after the MagnaFlow cat-back:


Here is a 2000 Camaro Z28 single turbo, custom headers, stock short-block, custom tuning with stock catback vs MagnaFlow cat-back:

 

How is the sound of the magnaflow catback?? Deep rumble, middle of the road or higher pitch?? How would LT headers and high flow cats affect it??

I concur

 

My magnaflow has a sound of its own i think and i love it. Go to LS1sounds.com and check it out. Im sure you will like it because all i get is compliments.

My magnaflow sounds very deep but then again its all very subjective. My only complaint it was not as loud as I imagined but thats only if I'm cruising. At WOT this thing screams and it just sucks that the Mustang GTs sound so much better with minimal exhaust mods. 4.6 liters should never beat 5.7!!

 

Yeah all I get is compliments unless I'm responding to a fire/rescue call at 3:00am.

 

Specifically we designed the mufflers to be street legal and comfortable to cruise in ... minimal drone ... comfortable intereior exhaust level ... SAEJ1169 noise compliant.

I will be designing a 3.5" diameter system with a turn down outlet for the racer looking for that MEAN and AGGRESSIVE exhaust note. This will not be a SAE J1169 complaint product. Also look for a new look system for those looking for somethign other than the singlewall slash product offering we make now.

 

When can we expect the new goods to be out for sale? Thanks.
