Topic: Magnaflow 3" VS Solo Street Race

[Kuprito]

Well, my car has installed the MF 3" for 2 years and I was wondering if the Solo will improve the dyno numbers.

I am not looking for a louder exhaust, with the MF and 3" solo catless downpipe it has now I think it's enough sound for me, I am just looking for better performance. I know that the Solo doesn't have mufflers, so I thought I could weld one on the straight part of it (under the backbone) or tell Solo to weld one. My car is a daily driver so I don't want a track car sound.

I am getting a GT30R turbo in a short time, I don't know when exactly, but It will be this year.

Does it worth it? Will the muffler I want to install kill the HP I am looking for? Will I notice differences between MF and Solo with the k04? and with the GT30?

Thanks!

I hardly can give a straight answer, only the guys which tested can say it but I doubt you will find someone who did such test.

I wouldn't do such thing, the investment probably will not worth the gains. Work around the turbo and that can give you more than a replacement of MF with Solo.

[Kuprito]

Many people with MF went to Solo... I hope somebody can tell the truth about both exhausts.

And what about the 2.5" reducer of the MF? It has to kill HP...

In terms of what you will spend vs what power you will make, there are better ways to spend the money. If you don't like the sound of MF and that is important to you. Then you should buy what you like.

1) The gain, if any, will be marginal, and not worth the money it will cost to purchase and import it. I have had the MF system with and without a cat, the SP Race Pipe (3" single, no muffler) w/ cat, and now a custom SP system with a resonator. There are some differences, but not significant.
2) SP goes build systems WITH and W/O mufflers or resonators.

I was talking about the Street Race system.

I will be honest and say that changing to the Street Race will only yield minimal gains by itself.  The ECU learns down most of any exhaust gains, until you replace the cat.  A tune would be more bang for the buck.  If you did decide to change to the Street Race, then get a HF cat and that will make more of a difference.  Even the HF cat on the MF makes a difference.  The ECU does not learn down the HF cat.  PM me if you want more info on the HF cat.  One thing is for sure, our HF cat with the Street Race will sound a heck of a lot more aggressive!!

Steve he is tuned already. He prepares for big turbo. His question was referring to that case.

Thanks Kelu!

PLEASE, Spicy3480, read my first message, I spent a few minutes to clarify the situation.

The car has no cat, it has a 3" solo decat downpipe.

The car has a 3" BTF intake and it's tuned by werks racing.

A GT30R is coming soon.

Honestly the gains as everyone has said will be minimally.
Also if the MF is loud the SOLO race will be just as loud maybe even more.

[spicy3480]

Our Race exhaust is louder than Magnaflow...When I first got m car 3 years ago, I had Magnaflow....the Solo is much louder with no mufflers. 

[IBDRINKEN]

yes the solo is loud as i have the hf cat with the street race for almost 3 years now and love it

What I can add is the Solo Performance mufflers are designed for maximum flow for our cars.  MF is a off the shelf muffler slapped into a pipe with a 2.5" neck.  Since you have a Solo catless DP, you may be experiencing drone with the magnaflow.  I know I did.  Then I switched to the Mach Shorty.  True 3" with a great muffler.  The Solo Street race is very obnoxious when you first start your car and at speeds 120 KPH

[spicy3480]

Deepbluegxp is spot on!  Cold starts are loud...when you floor it, it is LOUD!  Our mufflers are made for flow, and have an X design inside, similar to an external X pipe.  We surround the X pipe with the muffler, giving it higher flow rates while keeping noise to a minimum.  The catless DP and Street race would be the loudest combination we offer, and also the most free-flowing.

I was thinking of buying a Solo street race exhaust with the free flow cat but Jeff @ Solo thinks that setup is very loud and recommended a muffler with the free flow cat or use the stock cat with the street race. I have a Harley with drag pipes which is loud so I am used to loud but I do not have to have crazy loud.  I thought the stock cat was supposed to be too restrictive to flow?  So that would make me lean toward crazy loud or free flow cat with Mach shorty. What do you think?

[DeepBlueGXP]

Street race w/high flow makes it almost unbearable at 55-60 mph.  I have the high flow with mach shorty.  It has a very aggressive sound and burble is great, cruising is great in the cabin.

[Kelu]

I have race downpipe and mach shorty and is loud at high rpm. Cruising is pretty ok but on 12h drives I wish it would be quieter.

[DeepBlueGXP]

Kelu, you have a catless downpipe right?

[BigSal]

I have the same setup as Joe (High Flow Cat w/ Mach Shorty) and agree with his comments 100%. very aggressive when stomped on but still nice sound the rest of the time. I love the sound now. Money well spent as far as I'm concerned.

Kelu, you have a catless downpipe right?

Yes sir, catless downpipe = race downpipe, this is how I'm calling it.
