Has anyone seen or heard this set up?

[T-REX]

I gave my car to an exaust shop to do my exaust. I gave them the down pipe the test pipe instead of a cat, the cat-back, and a mangnaflow 3 in 6in around muffler. The guy welded the muffler where the cat shoud of been and just ran the pipe from there to the back of the car. So basically my muffler is in the middle of the car. I haven't heard it yet. Is this ok and has anye done this before? Will it be real loud? Any help will be appreciated because I don't know if he messed anything up.
thanks

that's where mine is, but its a side exit

How does it sound? Real loud? Will it affect me with mine comming out fo the back instead of the side?

sounds great to me. don't know if it will have an effect with it coming out the back. possibly louder b/c the exhaust is moving through it faster?? I'm just guessing. it sounds quiet compared to an open DP all depends on what you think is loud.

Thats fine, most cars have the mufflers in the middle. My vans is in the middle, most of GM's small and midsize cars are in the middle. The only bad thing would be if he mounts it with in a foot or so of the outlet of the turbo, I heard this is bad as it causes the exhaust gases to bounce, reverberate, on either a NA or turbo car!

I'm not familiar with that muffler , but if it's a straight through design , it'll sound better that way . Throatier and it'll eliminate the cackling on closed throttle decel associated with a straight through or straight pipe setup .

hahaha no it won't eliminate the crackling. nothing short of running 2 cats and a muffler will on a 3" setup :big grin:

the way i have mine (if you haven't heard my video's yet) is downpipe to ultraflow 3" !! it's loud!

[kedavis]

that crackling is your ecu leaning out fuel under vaccum you wont get ride of that.

I got that setup on my car. Sounds great. Although it sits so close to the ground that it will sometimes scrape going into parking lots. And it will sometimes hit the bottom of the car. Both of these dont really bother me too much. THe hitting of the bottom of the car confused me for a while until I figured out what it was, because I could hear stuff in the center console moving around, and I took it all out, and still noises. Thats when I figured out it was the muffler hitting. Although with that setup, I would not recommend any long or important cell phone conversations while driving it.

Not rid of it , but you won't hear it .

[89daytonaTII]

believe me you still hear it. my setup is a 2.5" DP into a 3" ultraflo then a 3" side exit. decel = snap, crackle, pop

[turbovanman]

That snap, crackle pop is the mixture doing its thing in the exhaust manifold. I think the turbo pulling the charge into the manifold or creating a vacuum and causing these mini explosions. If you notice, even huge exhaust systems on NA cars don't crackle in the exhaust under decel, and they barely do it with open exhaust :big grin:

Those snap , crackle , pop noises , will dissipate in an area of expansion , where applicable . Similar in effect to a motor losing compression . A large expansion area(muffler) is sufficient alone to render them inaudible , or with a small expansion (small muffler/glasspack) the more pipe you have after this expansion area , the less likely you are to hear it . I run a full 3" exhaust with no audible decel crackling . It's a JRB kit and I ran it in straight pipe form for about two weeks and didn't care for it from the first time I let off the throttle (sounded sweet accelerating). I added the muffler and it's great now . It's not quiet though ...

My setup...

FM TBI header

Turbonetics bad-boy turbo (it's big don't worry about the specs..hehe)

2.5-inch downpipe

No cat (dynomax bullet 2.5-inch in it's place)

MagnaFlow oval out the back (2.5-inch in and out)

Not a single snap, crackle, or pop to be heard in my setup. Just a very deep smooth sound.


Tune the timing and fuel...and you can eliminate that snap, crackle, pop if you want. Takes some skills though if you don't have programmable.
