Do you think there would be any performance gains when switching from a straight test pipe to a high glow cat?

 

Gains from a regular pipe to a high flow converter?? The converter won't flow as good as a pipe even if it is high flow.

 

Wupps. Sorry, bass ackwards. I meant switching from a free flow cat to a straight pipe.

 

Ah, then just reverse my reply.

 

the gains will be negligent i wouldnt do it , high flow cats are bettter( sounds bettter, pass emissions)

 

Well, sound is an issue of personal taste. As far as emissions go, I'm running 2 cats with pipes through both. Passed 3 years in row so far with no problems.

 

I am not running a cat (free flow pipe), edelbrock headers and a custom 3" exhaust system w/ flowmaster 80 series and I don't think it sounds bad....pass emissions, maybe not but I am in Michigan.
Here is what it sounds like

I would just stick with the hi flo one, unless it needs replacing you're not going to notice much of a butt dyno difference.

 

Well, right now I have the stock one (100,000mi.) I was just wondering if there was much of a difference between the two, hp wise. I don't have any emmissions testing, but if it's pretty loud I may get a visual inspection by the cops. The made-to-fit test pipes aren't much cheaper than many of the free-flow cats.

 

i would just go with a high flow cat then. That way its legal so ur not worried about getting hassled.

 

so you think by putting a cat on a 69 camaro would sound better?

 

Is that in just in your area u have emissions, cause i know i dont have to through them.

 

No i do not have emission testing in my area either. I didn't know there was another Michigander on this site. You need to come over to www.camaroz28.com/messagebd and go to the Michigan board. So many people there, gatherings, races, lots of fun stuff. I am in the car club out of detroit Motown Muscle. ( www.motownmuscle.com ) The Michigan GM Gathering/Race event is Oct. 5th at Mid-Michigan Motorplex in Stanton Michigan. Suppose to be a huge turnout with lots of cool stuff and u get to race all day at the nicest strip in Michigan. IM me on AIM sometime or E-mail me.

cost of high flow cat= $100
cost of test pipe=$12

spending the rest (78 bucks + 10 for your gas tank) to get the title for a 86 sport coupe, priceless

 

I've never seen a decent test pipe for $12

 

where can I get a test pipe at? or if someone wants to get rid of one I will swap them a muffler for it...

 

Just go to your local Meineke or Midas shop & have one made. I paid $15 for one.

 

test pipe/off road pipe/ cat delete pipe, its all the same, I went to napa, got a 2 1/2 inch pipe, cut the cat off, kept the 'butt plate' welded the pipe to the butt plate, 12 bucks

 

wont the local shops give you a hassle if your in a strick emissions zone??? which i am in one.... plus i got the A.I.R. so i need the air tube also that would go into it, and i dont feel like spending 75$ on the mac offroad pipe..
