i have them on my truck, not sure how the install went because i had my mechanic do it. I like the sound a lot, nice deep tone, especially around 2000rpm

 

are you taling about the Heartthrob?

 

yea the heartthrob ones

 

okay is it realy loud?

 

its not too loud when you're cruising but it you get a pretty nice roar when you accelerate

 

MBRP is about 400 for the 409 SS cool duals shipped to your front door.... I think you can go with a SI-SO for low 300 IIRC. Install on the cool duals was cake... 2 hrs or so once you figure it all out. It still looks rather shiny. A hint of browning in color but that was a given when I bought them. The 304 SS is a bit more for both but wont lose the luster.

PS Autoanything.com has the best prices with a 1 yr guarantee!

 

okay thanks that seems like a good price

 

I posted some promo codes that should work, like welcome15. IF you look around, I cant remember if we do, but DF might even have a promo code now too that AA is a sponsor.

 

ahhh I don't know what your acronyms mean!

haha

 

I am sorry. Here's the definitions of each.

SS - Stainless Steel

SI - Single In (refers to the muffler, single pipe in or single pipe out)

SO - Single Out

IIRC - If I Recall Correctly

The 304 and 409 are the types of stainless with different percentages of the elemental make up of the steel. Does that help
