Cat bypass and Dynomax muffler combo guys please chime in.
 
First I got a count on people with the cat bypass and muffler bypass and the overall tone is that it's WAY too loud for street use.
I have seen a couple of vids of people with cat bypass and dynomax but I would like to hear from everyone that has this setup. Seems like it's a great combo for the price. It also seems that some people have a cat bypass and Bursch muffler which is actually a Dynomax muffler, is this right? I would obviously be looking for a 1 in 1 out muffler and this one maybe a right part number. http://store.summitracing.com/egnsearch.asp?Ntk=KeywordSearch&DDS=1&Ntt=WLK%2D17 676&x=0&y=0&N=+115&searchinresults=false
Look at that price!
Let's see this combo!!!:p

I've had this set-up on my SC for about a year and a half, and even now I am still hooked on the sound that comes out that tail pipe. It doesn't matter if it's 50 degrees outside (cold for Cali) I must have the window down, so I can hear that steady rumble when I'm cruising, and that ferocious roar when I step on it.

Ditto.

I have the same thing on my SC, except a Flowmax instead of Dynomax (pretty much same thing).

It's perfect. Have people stop and tell me how nice it souds.

Does anyone have an opinion on Fabspeed to OEM 1 in 1 out? Sorry about the Jack.

I have the combo as well. I'll try to get you some audio clips.

This is an onboard shot but you can't really hear it. It's definitely louder than that :D

I have the dynomax w/custom headers (and no cat). Loud, which I like. Sounds AWESOME on throttle. The car plain sounds mean (which it is:D).

For you guys that have a 1 in 1 out Dynomax, can you tell me what muffler you used? Part #s even?

I installed the GHL stainless bypass with my Bursch but somehow the pipe was not right and the muffler hung off to the side funny. I have sent it back to GHL to look at and send another. As soon as its all here and together I'll post.

Did you see this thread? Dynomax 17725

i used the Dynamax WLK-17676, which you saw in the above posted thread :)
personally i don't think it's too loud, it is a sports car so it's supposed to be a little loud :D
imo if you kept your cat and used the dynamax muffler then it wouldn't be nearly as loud, but a little loud is good when it sounds good......

Please post a outside the car clip if you ever get one. Thanks. Sorry about the snow in!
