Ok guys I am just trying to make my mind up here. I am very happy with the mods I have right now. Check my sig if you don't know. I was going to tie it all up with a tune. Now I am wondering how much louder is the hi-flow cat? My car is not much louder than stock with what I have. Of course this is not an immediate purchase here since I am addicted to that WR screen that I saw on ihawk95 so that will be my next mod more than likely. I am just trying to get an idea on the sound. Internet clips never do it justice.

I have the HF cat by SOLO and it makes the car about 10-15% louder. I have an intake and the SOLO RCD-II exhaust system with the MACH shorty muffler and it got about 15% louder with the HF cat by SOLO. With your setup, I would think a bit closer to 10% louder. The intercooler and tune I have also changed the sound of the exhaust...it got lower/deeper and maybe 5% louder. The power gains are very nice, though, and well worth the money, especially if you couple it with a tune.
Okay guys, please help me out here. The final touch to my exhaust is going to be a high-flow cat. I have the entire Dejon package with intercooler, pipes, CAI, and BOV spring, along with a Flowmaster 40 muffler swap. Would a high-flow cat be a nice addition? If so which one should I get? Thank you for any ideas you can send my way.

It would be a nice addition. Get the SOLO HF cat. You get a nice performance gain and the exhaust will get about 10% louder. You can't go wrong with SOLO and they have amazing customer service. I have it and I love it.
Thanks spiky I just might have to go this way. At around 10% louder it means you can still hold a conversation in the car. I did not know that a tune could change the tone. Wow thats new to me!

Yea since the tune changes the timing advance, it deepens the tone by a small amount. The intercooler also deepens it. The HF cat makes it louder. The combination makes it sound more like a big V6 or smaller V8, closer to a biogger V6.

I have the Mach SHorty and Hiflow cat great system sounds good to me.
i have installed the whole shebang from the header to the SQR2 exhaust and high Cat. I love the sound especially when you get in between a couple of buildings downtown and light her up. It will be interesting as i sent my ECM to Westers yesterday to see the performance and sound i should get with the retune.

That's when I go "damm this things is loud" . Underpasses are cool too .
SS, the cat made mine significantly louder. It's not bad, but I sure as heck wouldn't want it any louder. I would be surprised if you didn't experience a healthy difference.
I had the Vector tune while my car was still an na car. I don't remember any difference in the sound of the car, just performance and driveability. If I hadn't gone SC a couple of months later, this would have been a very good investment.
Not sure were all comparing apples to apples here as some guys have GXP's, some guys have different cat backs etc.
MMmmm, Solo HF Cat make car go Vroom Vroooooom zzzzzoooom!
(get it)
(don't forget)
Get it
