Went from o/r h to catted x... big loss of power?

[GreenSnake]

I put on a Bassani catted x pipe fri. I can feel an improvement from 1-3k, but after that it falls on its face. with the o/r it was the exact opposite. It is really cold here so maybe IMRC's are sticking? Any suggestions? Oh it is really quite with LM1's and a catted x in case you guys wanted to know haha

Subscribing

Did the same switch, the car feels a lot smoother in accelerations and when I downshift, everything seems so ''linear''. Can't say much about power, but I kinda notice a drop in performance, but still it could be the fact that it doesn't sound the same... You know, like your girlfriend complaining about fast driving while you're just doing 70 mph and the car (o/r) sounds like you're doing 90...

A few things . . A. when it comes to cats and no cats unless your car has some form of forced induc your not going to see a BIG diff on the dyno chart, granted u may feel a diff because if your down 10 rwhp through the entire rpm range then the car will just act diffrent.

As far as suggestions . . Lt's from BBK into a BBK o/r X pipe with dumps (thats what i run and its the BEST ! lol ) :rockon:

haha I put a catted pipe on for a reason. It makes sense that you feel the difference when you don't have that much power. The rpm's don't pull as hard as they did stock though. It was normal right after I put it on, but today the car is sluggish. Maybe it's just having a bad

I did the opposite. Catted X to O/R H. My mph picked up at the track.

I've always wondered how some guys can notice anything in such a little difference in power.

Possibly something got screwed up in the process. When I made the switch I didn't notice a thing. Keep us posted on the outcome.

How much of a gain did you see. Just curious.

If I remember.... I was trapping high 105's (low 13's) and then it went to low 107's. Went from 13.3's to 13.0's. Weather conditions were about the same.

With 3.73, EVERY loss of power is PITA, you have all the time to notice how slow the damn rpm's climbs... I need money so bad so I can go 4.30 :burnout:

Hey GreenSnake,

Let me know if you're looking to sell the o/r h. I've been looking for a used on and havne't seen one up for sale in a while. I don't want a new one because I'm not sure I'll like the increased noise or smell. (I'm sure I'll LOVE the sound, but not sure about the noise). Thanks.

And about the power loss, it might just be psychological. However, I guess it would make sense that with cats, you get a bit more back pressure, which would help out low end torque, which our engines are desperately lacking. Then, as you get into the higher rpms, the back pressure starts to work against you, as the engine is making more power. And then flip that around for the O/R pipe, and it makes sense.

My car felt faster with the catted X than with the o/r h. Felt like it had more bottom end with the H and more top end with the X. And that is also with BBk Lts

Haha what about some Royal Purple?


uofipilot- I'm debating putting the o/r h back on. The catted x isn't my thing, and I am just re-registering my car in Georgia hopefully. If I ever sell my car and I still have the h pipe, I'll send you a pm.

I think it might have been something acting up due to the cold weather because the car is working fine now. It revs like it did before. Now I just don't go deaf at wot anymore.

 

[carkrazy]

I would put a VRS o/r X and call it a day.

 

[uofipilot]

Hoe it works out for ya. I don't think I want the h anymore though, so no worries. I was gonna dump a bunch of money into it this winter, but I think I might just sell it in the spring and get an 03 or 04. Who knows, so right now, I'm not gonna dump anymore cash into it.
