I'm looking at MPx catless downpipe. For your info, Ontario has rigurous emissions testing once the car hits 5 years old. It's only 1 year old, so I figured i would install it, and when I need to get tested swap the stock back in to pass.

I have a muffler delete already.

1) How much louder will it be with a catless downpipe?

2) How bad will the car exhaust smell?

3) For those of you who live in Ontario, what's the worst thing that could happen to me if I get pulled over and they check my automobile?

 

I have zzp's catless dp and their 3 inch catback w/o a res and its not loud at idle, only when you get on it. It sounds really good in my opinion

 

if you got catless you may throw a cel and it will then probably come back if its only cleared. If you have an aftermarket tune, hpt, trif. etc you can have it fixed.

1. with the muff delete its kinda loud...too loud for my taste. Theres some vids on youtube
2. I hear you'll smell it at idle a little
3. dunno

I'm only on gm stage 1 kit, and after reading about the catless and how it can throw a cel. I'm just getting a high flow cat dp so I dont have to deal with it.

 

you can definitely smell it at idle. if a cop pulls you over turn off your car.

catless AND MD and you're easily THAT guy. no thanks.
