This may be a stupid question, but I had to ask to get some clarification.

1. Is cat delete the same as a test pipe?

2. Do people with cat delete or test pipe experience a bad exhaust smell.

3. Is there any difference in HP gained from a cat delete compared to a high flow cat.

I'm trying to decide b/w a few different options for a turbo back.

Thanks!

 

ultimate racing has a good test pipe (cat delete)no cel light.bad smell don't smell it lol.hp gaine's i heard 5 to 10 hp with no cat i think.

 

1. same thing
2. no smells yet
3.yes nice gains

 

definately smells unpleasant but yes, very good power gain (u can feel it instantly) Must say it a 10+hp gain.

 

aside from all the smells and junk, if your running a full turbo back with no cat don't get stuck in front of a cop... The evo and sti are both prone to throw fire at times..... Pretty cool i guess but not cool if u get stopped... Reason being the car run's so stinking rich...
