I am going to be purchasing the Dynatech longtubes with the high flow cats very soon, just kind of curious what kind of gains I should expect from these? I already have a cam, nelson tune, cai, cat-back exhaust and a few other minor things done. I should see at least .2-.3 reduction in the 1/4 shouldn't I? My pcm will be tuned for them right away also. Hoping the gains are noticeable considering the Dynatech system is $1200.

 

I know this has probably been discussed before and it might be hard to tell what I would gain but I am just having second thoughts about spending over a grand for something that might only knock off a tenth or so.

 

Why the dynatechs? I would save the money and get pacesetters or stainless works ooorrrrr asm's, all alot cheaper.

 

Yup I agree get you some stainless works headers the dyntechs arent worth it to buy brand new. Im gettin mine hopefully used. You should expect about 25hp or so from them not 1200bucks worth IMO. Get you a set of carsound or magnaflow high flow cats and you will save about 500 bucks and maybe get 1-2 less hp. Spend your moeny elsewhere like being able to upgrade your hidden system that we talked about.

 

not knocking the quality or performance of the dyna's, but why spend $$$$ for them when you could get a set of pacesetters that would perform within 5hp for $399?

 

Long tube owners, lets stick to the topic . How many tenths could a new lt owner expect to see ?

 

oops, sorry. couldn't tell ya how much time, would all depend on your combo, but i would bet at least .2.

 

He cant get pacestters guys he has an SS pacesetters dont fir 4wd's or awd's. He has to get TOGs AS&Ms Stainless Works or Dyna's.

 

double oops...i'll just shut up now and go sit in the corner.

 

Mine went down from 15.2 to 14.7 after installing my LT headers and removing the cats...
