Hey guys I want to buy spin tech muffler for my 454. I do not know which ones to buy. I would like a muffler about as loud as a flowmaster 40. But I picked the spin tech for the interior noise and different sound. I am just insure which one to buy. Flowmaster 40 is almost exactly how loud I want my car to be.

thanks for any help

I like their 'pro street' muffler, that's what I run.

I ran the Sportsman Streets for a while, and loved them.

Might have a video. I'll look in a bit

thanks guys for the help. Which do you think the pro streets or the sportman street are closer to the "loudness" of a flowmaster 40 series?

thanks
Tom

The Pro Streets will be similar in noise level to the Flowmaster 40 series. A couple of friends have the Pro Streets and they are very, very noisy outside the vehicle-- much like a Flowmaster 40 series. They do have less interior noise and resonance than a Flowmaster 40 though.

I'd rate the Sportsman to be in between a Flowmaster 40 and 50 series for loudness.

If you want to make a lot of noise and draw a lot of attention, Spintech is a good choice. :p

Where is a good place to buy them?

you pretty much have to order from them direct

Check Ebay they sell everything!
