Is this the HKS?

Man, I have a feeling that's going to be REALLY loud.

Will be interesting for sure, especially with the single tips.

single tips is going to look very out of place with the stock rear diffuser

I guess we are going to find out really soon . It's not my daily so load is not an issue for me . I stuck LTH on my old C63 AMG and that was the loudest I have ever heard from an N/A setup . I think the turbos will keep it somewhat tame compared to being straight piped .

Eventually I will be changing rear diffusers but there are a ton of vehicles with round tip exhausts and OEM rectangular cutouts . I might end up switching out tips eventually .

Are we "M" owners not the biggest bunch of knucklehead a-holes!

So I finally got around to installing the exhaust and I have to say , it sounds freakin' amazing . Cold start is pretty aggressive but once it warms up a bit , it sounds so smooth . I picked it up at night so didn't get to do a thorough inspection but I need to go back to get the tips straightened out a bit . Definitely glad I switched to the M40i style tip instead of staying with the round HKS tips .

This is the sound I was shooting for and I would say I got pretty damn close .

Here are a couple of pics to start and videos will come later .

Sounds awesome on the Supra. Can’t wait to hear it on the X.

Needs some quads.

It sounds amazing because we removed the valves so it's constant .

I thought about it initially but wanted it to be different than the OEM look . If I can find some bigger and badder quads then maybe I will switch them out .

Amazingly , it did not end up as loud as most might think . Cold start is pretty loud but that's to be expected from a downpipe / single mid / catback vehicle . After warmup , it has a nice smooth rumble and sounds great under load . I threw up a quick video of cold start and a few revs . Sorry for picture quality but it was quick . I will get better ones later on .


skip to :25 to avoid most of the cold start idle
