X-pipe setup question

I'm planing on long tubes and a shorty x-pipe, I live in Colorado an I'm not sure on the laws of a catless setup vs catted, I want to be able to take it out of state on road trips but not very often... How illegal is catless for road use? Lol I will also be taking it to the track quite often

Only time having no cats could become an issue is when your trying to pass emissions... I'm unsure as to CO laws on cats to be honest

Having trouble finding exact laws, just comments of people "getting away with no cats on forums" lol. Co has a ton of emission trap trucks on onramps to highways all the time, that's the only reason I'm worried, otherwise I would just switch back for emissions

Here in tx I get by with no cats. But its not a big pushed subject here so they don't really check.

I don't know what Colorado's laws are but just remember a full exhaust is going to be really loud both with or without high flow cats. If you're worried about laws then keep your cats. People forget you can still get a ticket for loud exhaust too. I think longtubes with a catted X is loud as it is. I had Pypes mid muffler and no cats and it was wake the dead loud even at 3k RPM even when accelerating normally. The high flow cat's at least let you be quiet when you're cruising or normal acceleration, but pretty **** loud when you want to be.

Not quite true. Dual chamber magnaflows are not that loud. Even with no cats.

Yea it sounds like my best bet since no one seems to know exactly out here what's legal and what's not. I think I'm gunna start out with stainless works lt headers and high flow catted x-pipe, see how it sounds then add either borlas s-type or atac axle back, just don't want it to sound too tuner and more thoaty. Stainless works lt setup looks too good to pass up tho

Your choice of words makes me want LTs and no cats

And to canter21... Borlas w/ LTs won't sound tuner... I promise

Thats what I wanted to hear thank you lol I just know that stainless works systems tends to sound less muscley, hence why I want Borla axle backs instead of the full stainless works system

This is what it sounded like and I didn't even have headers. This was on the factory manifolds too. I think you'll get the point of wake the dead loud. That's only 3k rpm shifting as well.



I agree 100% on the Borla with longtubes too, definitely maintains the throatiness and doesn't have the tuner sound compared to other setups.

I have BBK LT's and O/R X-pipe with "hushpowers" and it too is "wake the dead loud", almost made having hushpowers a joke really. My neighbors love it when I decide to go out for a midnight ride and it's super loud at startup when the temps are low. Keep in mind removing the cats will give you the awesome burnt-fuel smell, so if CO has road side emissions testing they may smell you at a stop and know your car is cat free. I would shut off the car at a check point or if you get pulled over.

With chambered mufflers it won't be wake the dead loud. I have a buddy with headers and o/r xpipe with the magflo's and his is not loud unless he is really getting into the throttle.

Being that ur going with the catted x pipe and chambered mufflers it will be just a lil louder than stock at lower rpm's but u should be able to make alil noise at higher rpm's. I have roush axlebacks and will be installing LT's and o/r x pipe so mine will be pretty sick! At WOT it will sound like a NASCAR passing! Go to Mylrs.com and type in the search box "stainless works header Install" scroll down and u will see a video of a red Stang with the same header set up that I have. Check it out
