How loud will this be with duals out the back, 2.5 inch pipes and 3.5-4 inch tips? Will it be nice at idle, loud when i get on it, and noticable at cruising?

I have a 3in single in dual 2.25in out with 3X18 stainless tips with a hollowed out front cat and no rear cat. It is very throaty when you get on it. It is definately not quiet at idle, but has a real nice sound during acceleration. I have this setup on my 94 F150 with a 302.

Most definately!! removing the rear cat will make a noticeablt difference in sound. I would suggest hollowing out the front cat and adding a single high flow cat where the old second cat was. Does the $260.00 include the muffler and tips? That sounds like a good price. Take care.

Yes the 260 dollars include everything parts & labor. I hope this will sound good. I'm sure it will.I'm thinkin for now i'm just gonna remove the rear cat and leave the front one alone will that cause any problems?

It'll sound sweet! And that's a good price too.
I have a 40 series dumped with no rear cat on my 351.

Sweeet! Glad to hear you like the new exhaust system. Chrome tips out back aren't redneck. I think they look good.
