I have a stock MR right now. I have a Perrin TBE (uninstalled). I just ordered some Kelfords too. How much louder will the cams make the exhaust tone? Is it noticeable? I bought the Perrin because it seems relatively quiet but sounds mean!

I have a sound clip on My sig. But with Invidia and Cos 272s, If you want to have an idea.

I've got the same combo perrin TBE and kelford 272's, havent gotten it retuned yet, but it is a little louder at idle, but in my garage there is a lot of echo as well.

Not much louder! When I did my Kelfords, the only think that really changed was my idle.

I did HKS 264s on an 05 MR and I thought the exhaust was a tad louder esp under acceleration in the mid range. Sounded good though.

what kinda power are you making on your setup, just curious? Boost level on 93oct?

I don't know, waiting to get it tuned still, but I will be posting info once I do.

pretty loud at idle also higher idle rpm, but nothing beats the sound of a 3" straight pipe evo with some cams! FTW

Congrats on the results. That is the number I am shooting for! If I can hit 350whp I'll be happy. Going down to CT for the install/tune this month! What are you revving to just out of curiousity? Are you going past the stock limiter, is that why you went with spring/retainers?

well it revs to about 8000 I think, havent tried going farther than that but havent hit the rev limiter either, But as you can see in my dynograph, the power drops down by 8000 anyways, so If I shift there, i am right back in the peak power band. It is on 93 octane and maxes out about 26 psi of boost. I went with the upgraded springs and retainers because the kelford 272's recommended upgrading, i'd just as well do it while I was already in there. I know the springs set cost almost as much as the cams but I would say its a good learning experience too if you do it yourself.
