To start off , i would like to say that for the last 5 months i have been building my car to be pushing out over 400hp. So far i think i am going to accomplish that and more. But i ran into a problem $5000 and five months later i am getting into a tight spending limit ( WEAR YOU CONDOMS KIDDIES) . I need a muffler to support this much power. I dont care about noise because the car will be a weekend racer. But like i said i am going tight for these upcoming months.

I dont want to spend $400 on a exhaust nor i want to spend 20 bucks on a ebay can that will catch on fire. What should i get for the the price range of $75-$100. I was loocking at some BORLAS xr-1 and maganaflow race mufflers but dont know if they will help.

guys help me here this is all i need to do to finish my car

 

Kick her in the stomach...hard. J/k. I think the magnaflow offers a warranty, so if something goes wrong just return it. I know O'Reilly Auto Parts is extremely lenient on returning ****. I work for them. It drives me nuts. They are supposed to take back damn near anything no matter what stupidity happened. Buy one through them and return if it goes sour.

 

I just ordered yesterday a Dynomax Ultra Flo SS muffler # 17267 - 6" round, 3" in/out, 16" overall. Alot of the ITS guys appear to be running this. According to Dynomax it has a flow rate of 2000 SCFM and will handle up to 909 horsepower on a single muffler setup. I don't have the horsepower you do but we run at high RPM constantly. Cost me $130 or so from Summit, local place quoted over $200 just for muffler.

BTW, this is going on a 13b NA race car. Dynomax also has a race bullet but I opted for ultra flo, don't know why but that appears to be the popular choice plus we do have sound control to consider. I'm running race header, 3" pipe, muffler.

 

Borla XR1 tripple core is $400. You can get a universal Magnaflow with tip for like $150 then all you need is the mandrel pipes and somewone to weld it. If you can fit it, add a universal presilencer (2ng gen) from Racing Beat (another $100). Unless you are dual exhaust.

 

El Nene,

Check out Goodfella's setup. He's running a full 4" exhaust with a couple of magnaflows. The SS Magnaflows seem to work very well. CMonaker also ran a custom 3.5" exhaust on his single turbo setup for a while with good results. The Magnaflows do the job and are pretty cost effective.

You doing a full custom exhaust or what? You also need to use some reasonably thick walled tubing on the exhaust.
