Has anybody purchased one of these yet? Was wondering if it really produced 11 hp or any gain, and more importantly how did it effect the sound of your exhaust? I will be running frankencar intake/ budget y/ maybe racing pipe/ stock canister. Anyone running that combination? Thoughts on how that combo will sound? Thanks.

 

HP gain...most likely. Louder exhaust..yes. Change the tone of the ehaust...yes.

 

Don't you mean:

HP gain...not likely

You wont get 11hp from a test pipe.

 

For the price I figure if your going to get 3HP gains from it why not use warpspeedperformance.com or testpipe.com? I mean these two are in the 30 dollar range compared to the custommaxima one.

I got a "test pipe" on e-bay shipped for 25 bucks. It didn't change my exhaust tone at all (but i only have a muffler on stop b-pipe which i have to add sounds great, its quiet most of the time, but deep under wot, and rumbles at 2.5 - 2.7k rpms. I can't say i felt a difference in HP either. But i haven't tracked, or dyno'd my max yet so who knows. I can tell you that if your cars like mine, you're bolts will be damn near if not impossible to get off the cat because of rush. I had to take it to a shop and have them melt them off. Cost me 50 bucks too which ****ed me off.

 

Just get a high flow cat. Emissions testing is coming to everyone sooner or later. You will be ****ed off when you have to put your original cat back on at that point (if you can even find it then). Unless you have a propane torch at home, you will have to spend labor twice at a muffler shop to remove those rusty bolts...

 

Compare to an OEM cat with over 100K miles on it, yes there will be gains. 11hp is possible. Compare to a brand spanking new OEM cat, maybe 1-2HP.

 

Nothing some anti-seize compound wouldn't prevent. I had a RT cat before and that was a waste of money.

 

I just but on a test pipe replacing my cat with 108k on it and I'll have to say I can feel the difference....it revs alot faster and throttle response is better....that is with a b-pipe and muffler though...

 

Which pipe did you go with? How much? Did you notice a big difference in sound?

 

Well its a warpspeed, its not mine though its a friends....he had to put his cat back on so I tired it on for size...in terms of sound it wasnt big, although I havent head my car in drive from the outside...its a little bit more metalic and rougher..
