I heard an LT1 F-body last night with Spintech mufflers, and man was I impressed.

Anyone running Spintech mufflers on a truck? What is the inlet/outlet size and position so I can order one? Any sponsors carry the individual mufflers? Anywhere that I can get one if sponsors don't carry them?

Thanks!

Let me know if you go with these, I've been thinking about changing mufflers again, and would like to see how these perform.

 

what is the inlet/outlet size of the muffler? I've heard 2.5 and 3 inch...which is correct?

 

I would run 2.5" with these trucks. I've learned that a small amount of backpressure is needed to keep some lowend torque. 3" may be too much. I'm not sure what setup your running, but I'm happy with my 2.5" size. I did loose some lowend, but I'm also running straight through design mufflers. I'm not sure which size to go with, the mufflers on there site look like they might be a little big to run 2 mufflers... You wanna be the guinea pig?

 

I'm almost sure that I'm going to order one. I would run duals, but with a slammed truck, I don't have a lot of options!

I'll be the guinea pig!

 

go with the spintech pro streets, they are very small and low profile, probably good for lowered trucks, and they sound good

 

Stock size is 2.75"

 

Here's a link to a brochure I got from them.

Thanks for the info!

 

I've got a set with the X-Pipe on order. I'll let you know what I think when I get them on.
