Default 2004 Sti catback-q300 vs Cobb vs Perrin...

I have a stock 2004 sti and Iím looking for recommendations for a catback exhaust. I know these have been discussed before, but a lot of the posts for these single exit exhausts are pretty old, and maybe they have had changes, etc.
For comparison I have a 2002 Wrx with a catless dp and stromung twin tip catback. I want something a bit louder than that. I will be utilizing the stock downpipe this time for now. From reading old post it seems Cobb and stromung are the same thing? Maybe my stromung being twin tip makes it more quiet? I want something that comes straight out the rear and is not angled up to the side. I think my options are either Cobb, invidia q300, or Perrin. Has anyone heard these systems, and which would be louder?

If you want loud, look into the Blitz Nur Spec R or TXS RFL.

Not much has changed for GD chassis options. If you want straight exit, Cobb is a good choice. No drone, but sounds great when you get on it.

Agree.

I switched from a too loud CBE (Greddy Ti-C) to the Cobb. Ran it with headers and catless DP.

The Cobb CBE is dramatically quieter.
No droning.
Sounds loud when you get on it, but not so loud as to be obnoxious (all relative).

Seems like Cobb is definitely most popular for a reason. I like how it doesnít need an adapter for the stock downpipe too. Iím going to watch for the next week or too hopefully thereís a discount on one somewhere.

Has anyone heard both the Cobb catback and the turbo xs catback? I can find it for a couple hundred cheaper. The muffler looks really similar and it has a nice tip. Not canister/angled.

I have a different Invidia system so I can't speak to sound, but I can speak to quality. I've had that exhaust for 10 years, 5 of that living in the rust belt. It's still in great shape and sounds like the day I bought it.

Read the post titled Exhaust FAQ...find it and read it. The answers may be old, but they are 100% valid even today.
