Re-visit: Mufflers for turbos?
 

I know this has been visited before but....

What's a good muffler to use with turbos? I went commando with my car a while, and then to bullet mufflers. Either way, the car sounded more like a farm truck than a high performance twin-turbo stroker motor.

Which mufflers are a no-no, and which are good? Which cost the least power, etc?

a "no-no" would be a chamber type muffler. Any of the straight through type mufflers like Dynomax Ultra-flows, Stainless Works, Borla, etc. should work well.

less is more...

straight thru mufflers ONLY... and teh bigger the better.. so 3 inch or more.. the turbos take almost all the sound anyway

I agree Jody chambered mufflers will not work with Turbo applications. Plus the suck to package under a car.

- Stainless works & Borla have always worked well.

So you're saying the "turbo" mufflers are not good for turbos? Damn marketing companies! :willy:




JUST KIDDING! I do know better, honestly. Now I gotta go top off my blinker fluid, but I can't find the dipstick.....:_paranoid

Yeah, I have 3" Dynomax bullets now. They took out some of the drone but sound like poo, IMO. Kinda like glasspacks. They really don't do the engine justice.

What about Spin-Techs? Would you still call them chambered? How do they sound?

There is a small shop called T-Phlo. His name is Tim and he hand builds awesome turbo mufflers. I use them on my twin turbo 438w and they are awesome.9095283249 Tell him ken sent you with the 67. Best sound ever!!

I wouldn't do Spintechs... there are plenty of "obstacles" inside them. Go for anything straight through. You can ask Jody about what happens with the wrong mufflers on a turbo application. (not his fault though, they came with the car...) :)

The best straight through style mufflers I've ever heard are Borla XR-1. They're expensive compared to other similar mufflers and there aren't many case configuration options for inlet and outlet but they do a good job and sound fantastic. The XR-1 Sportsmans are the "single core" design and are louder than the Multicore versions.

I ran Magnaflows on my old Procharged 353 and liked them, I'm keeping them with the TT LS2.

I have the magnaflow ls1 single turbo not loud ,I guess it's the farm truck sound so far best sound was no muffler but I couln't take the drone. Bob
