Blew sound at local event - quiet single exit exhaust?
#21
I like the sound of AAM which the OP is talking about here but I want to custom build it locally (shipping from US to my country would probably cost as much as the exhaust itself!) - that's why I'm wondering how it's built.
jledford, can you let me know pls.

As long as its not rattling against anything fitment wise all the exhausts seem to fit tight. The back bumper tho will melt if the muffler is touching. It should be quieter than the Tomei being stainless. Stainless is going to weigh more than titanium. My custom exhaust is light only because of the Burns race mufflers used.
I'm going to have to do something about the bumper because it's definitely touching slightly at this point. Are the bumper "tucks" that a lot of the street cars do frowned upon in STU? Or would that be legal / no one would protest?
I knew the stainless was going to weigh more, also deadens the sound better. I just wanted a before and after weight to see what it cost me in weight to meet sound.
I might look into a custom muffler, there's a very good fab shop within a couple of hours of me that could fix any issues I'm having with fitment and replace the muffler.

Which part do you have a question about?
I don't feel like I lost any power vs the stock muffler. In fact when I first put the Tomei on it felt like I gained some power just from seat of the pants. No big difference in feel when I went from Tomei to AAM, just a lot quieter.
I haven't had it dyno'd or tuned at this point but I see no way that a 3" y-pipe back could lose power and I'd assume after a tune it can only help increase power.

What is the diameter of each part - Y pipe and the rest? Do you still have the original cats? - edit: nevermind, I read now that you have all stock parts and just a 3'' aftermarket exit.
The problem is related to the loss of back pressure in some systems which are built more for FI cars rather then NA ones.
Is this how it sounds on your car? I'm wondering how much louder it will be if you were to remove tha cats and replace them with resonated test pipes?
This guy has it installed with aftermarket test pipes and Y pipe:

I currently have stock headers, stock cats, and stock y-pipe. So at this point mine sounds more like the 1st video than the 2nd. The 2nd video is closer to how the Tomei sounded, but still think the Tomei sounded better.
I want to do PPE long tube headers and y-pipe with high flow cats over the winter, I'm sure the sound will be louder then but hoping not too much.

I really like the sound of the second one but it's hard to say how loud it's going to be with resonated test pipes. I hope a custom made muffler with take care of that.
By the way, wouldn't the PPE headers replace the cats? They go straight into the Y pipe as far as I know. It will be crazy loud!
