Catback exhaust

Okay well i just put in a flowmaster muffler and a tip. cant really hear anything unless your at idle. i just wanted to make sure i have my facts right. a catback is one muffler and two pipes heading out of it? dual mufflers mean that the truck has two mufflers comming out of it? right? the local guy here said he can do a catback for $350 and was talking about dual for $450. im guessing $450 is a good deal if its only a hundred more for adding another muffler. thanks

catback exhaust is any exhaust the attatches after the catalytic converters. it doesn't matter if it's dual pipes or not. there are 3 popular ways these usually go.



1 pipe into muffler, 1 pipe out of muffler

__________________________________________

1 pipe into muffler, 2 pipes out of muffler

__________________________________________


exhast is split, and each side of engine gets it's own muffler and exhaust pipe.


1. the $350 quote is for a single pipe catback exhaust. basically he's going to cut your 3 foot stock muffler off, and weld in a new "performance" muffler with a little pipe

2. the $450 quote will have the guy "Y-ing" out your exhast and installing all the associated piping to have 2 seperate exhaust tips. 1 pipe into a muffler, 2 pipes leave the muffler

$450 for a custom dual exhaust isn't bad, it isn't the best of prices either. I paid $479 (shipped) for a Magnaflow stainless steel dual exhaust. I had to install it myself though. It all depends on how mechanically competant you are.

sorry about the product images, I had a hard time finding suitable images to demonstrate what I was talking about. btw, I highly recommend Magnaflow.

you don't put mufflers before the cats...well, I've never heard of that done anyways.

I don't think that would gain you anything anyways.

ah ok thanks. one more thing. would a cat back with two pipes comming out of one muffler give you more sound of the muffler? or is it just for looks

it's a style thing. one pipe in and one pipe out won't quite sound the same as 1 pipe in 2 pipes out, but it'll come real close.

I prefer the 2 tailpipes myself, but alot of people go with 1 pipe that looks stock.

Look at some of the early to mid 90s Chevy C60s with a gaser in it they had the muffler before the cat

If you look at the pictures in my gallery you'll see that's how mine was done.
Might be what you're looking for. I really like it.

yeah rodneysch, exactly how i was looking to get mine done. also, i see some trucks with dual exhaust and their left pipe is swinging around when they drive. do the auto techs that install the mufflers put some kind of brace to make sure that doesnt happen? or do they leave the pipe as it is like that?

if the exhaust shop is any good at all, they'll install enough hangers to keep them from sliding around while driving.

just go out into the bay when they're doing the work. and tug on the pipes after the install is done. if they move more than an 1" or 2", they need more support

I don't think there's any real difference in sound between the dual exit of single exit. My single magnaflow can make just as many heads turn as a dual setup could, most people don't believe it's a single until they look at it. It has a nice deep sound. Dual mufflers would be a waste, and how is exits is totally based on your opinion of appearance. I really didn't want a hot tailpipe that close to the rear brake hose, and also didn't want to get "exhausted" hooking the trailer up, so I went with the single, and I'm glad I did. It can make just as much noise as duals.
