Sorry if this is a beat to death thread/post. tried searching.
I want to put a turbo back w/cat on my 06 MR.
I'd like something that dose not drone on the highway and is reasonably socially acceptable.
My thoughts were a full perrin turbo back. don't know the loud factor.
Or a Tanabe touring catback with a down pipe an hi flow cat.

I'm afraid the tanabe may hinder me later on.
Thoughts and comments appreciated.

Thanks Shoe

 

Yeah, I think this was discussed elsewhere... but here's my setup. I've got an Injen TBE, but I put the Perrin HFC in there. It's really quiet and makes good power. Overall, I've been happy running this setup for ~20,000 miles.

 

there are tons of exhaust threads

search or pm a few vendors and see what they offer that is quieter
