What im missing to squeeze more hp of my 3?

I seriously appreciate the feedback. This may be a lame question, but do you know what numbers they claim for gains on that system? I already ordered the system, but I saw the new vibrant system and they also offer a highflow cat system. They are claiming 10whp from stock and I believe 8-9lb ft tq. But I dont know what size piping they are using...

So if anyone knows the claims Draxas is making for hp & tq that would be great. And if anyone knows the size of vibrants piping also awesome!

To squeeze every last bit I would recommend the Marcy Motorsports Balance Shaft Removal Kit. PITA to install, but if you get a shop to do it it should only take a couple hours. (Total cost for mod: $150 with kit and shop time)

There's more, but I can't think of anything else right now.

i feel the car is a lot smoother thru out the rpms. No HUGE performence gain, but my butt dyno is making me happy. I have the one with the high flow cat since the off road pipe will be way too loud for my liking.

I took it to a muffler shop to get it done since I dont' have a lift, and i don't have any thing to cut off the old exhaust. It's doable with jackstands but I took it to a shop just because I do not have the tools and 2 set of hands.

how much was shipping and how much did they charge to install it

I don't remember the number, but the stock dyno for their mazda 3 put down 150 hp, so it was a little wonky, but comparing dynos on two different car with two different system in two different condition is like compare Halle barry and Zhang Ziyi.

Shipping for my kit was free because I got it during the initial run. Installed cost me I think it was 70 or 80 bucks CDN at a reputable muffler shop. I wanted it done right.

so would you say the exhaust is worth the money(did u get the high flow also)

I like your comparison. Both really hot, but TOTALLY different.

Well one thing you have to remember about the Draxas exhaust..it is made by Thermal Research and Development. Most of there exhaust for other cars make less HP/TQ than others exhaust manufacturers. Must be the types of HI-flow cats, resonators or mufflers.
And you will almost always make more power if you get the option without a hi-flow cat. Hi-flow cat still equals a small restriction.
But yes it will be louded.
