muffler choices.....

[stretchb]

so will i be wasting time and  $$ to dyno with this exhast  ??

i ordered a 3.5in bullet today for my down pipe and i am just going to run it.

[Nitmare89]

what does everyone think about Spintechs..mainly the pro street model

[84camaro]

i dont like the way any spintechs sound but we sell alot of them. they are supposed to sucj the exhaust out but i think will act the same as a chambered muffler.

[Pro Stock John]

I have a single turbo and single 4" exhaust dumped.  I had a 4" Dynomax bullet and I joke that the car was louder than open downpipe.  I just went to a Splitflow 4" muffler.  It's straight thru like an XR1. 

Here is a vid with my old 4" bullet... inside and out:

Here is a clip of the Pinks Camaro, NA and dual exhaust with bullets about a foot off the headers... very loud:

NOT THE BULLETS.   
Try Dynomax Round mufflers.

I've had that Ultraflow Welded big barrel muffler on my car too, when it was a 422ci NA setup.  I went from a 4" Flowmaster to that muffler.  That muffler sounds deep, and it's straight through.  It just won't fit under my passenger side seat where I have the Splitflow.

Cut and channel?
Hammer?

I have a 4" magnaflow that looks like the Dynomax in the pic above.  It does take up a lot of room...  On the shelf.  LOL, my Turbo Mustang has 3" oval Ultraflows.

[mootang]

of the straight through mufflers which ones are the quietest for idle and cruising?  I will be running turn downs and no cats. 

Right now i'm trying to decide between the following:

dynomax ultraflow's
magnaflow's
hooker Maxflow's
bassani (they make a cat back with turn downs for a decent price)

Mustangless, thanks for posting that!  I can't wait to fire up my baby with Spintech Sportsman's!!! woot woot!!!

Here thought I'd through these up here since I just got them uploaded.


Stock 5.0 twin t3's, 2 1/2" exhaust, Summit H-Pipe, and Summit Catback (yes it's restrictive).  Sounds bone stock, can't even hear the car over the sound of the fan, gets a little louder when you get on it, but not much.

Same exact setup as above except without the catback.  Noticeably louder now, sounds cool for a little bit, but gets annoying after a while.  The turbos spool a hell of a lot quicker now as I can actually get boost in first gear now.

Doesnt seem like there are alot of poeple using SLP catbacks on here.... mostly dynomax.  Im running SLP's on my car (NA) right now and really like them.  Its the LM1 catback so its a straight through design. You would think that more turbo guys would be running them.  Any reason why they arent?

I dunno...I had Dynomax straight-thru style mufflers on my old stock block setup also.

 I too was told the turbos quiet things down but sadly disagree. Here is my TT427 from the other night. I just installed Tang housings with 3-1/2" V-bands and upsized to 4" off a 3-1/2' 90*, these are dumped right after the engine. I am waiting on a pair of  Dynomax 4" Ultra Flows

Vibrant Perofmance 4" Single Race Can, Never Switching Mufflers Again!!

If anyone is needing one of these mufflers, feel free to let me know.  Below is a thread with sizes and pricing.

I didn't watch your link since my computer's so slow, but...

When I put 2 Dynomax race bullets (4") on my car that had a single 4" exhaust going straight back from the downpipe to the rear axle I didn't notice any change in noise at all from an open downpipe. They were both pretty much juast as loud as eachother with maybe a slight difference.

Now it has a dual 3.5" exhaust with some Borla mufflers and sounds much nicer.
