YEa i have a question? REmoving all ur cats will it loose power or not... i heard by some no u wont it will give u more and more noise..hear from others na it will loose power...... sowhats the real answer?,... has anybody tried it and felt the same..? or what... another quick question how long does it take to get stuffs from mustangtuning when u order?......and do they lagg it or not?

 

mustangtuning ships quick, i get my stuff usually in 2 days, i got my wheels the next day when i ordered. removing cats= removing restrictions so it shouldnt decrease power, im not sure about the gains, its mainly done for sound though not hp/tq gains

 

If you remove all cats youll lose a little bit of back pressure and on a NA car you need a little bit. Youd probably lose a little bit on the bottom end and maybe pickup just a bit on the top end as well as being noisy. Personally Id just a midpipe with a pair of free flowing cats.

 

To answer your question about the cats: "It depends"

On a near stock car with no cats and resonators instead of mufflers, you will loose power. If you remove the cats, but have a baffled style muffler, you should see some gains. In the end, no matter what catback or mid pipe combo you pick, don't expect any more than about 15 rwhp.

On a blower car, the gains are bigger.

 

well i got me a cat back system but still got the stock h-pipe

 

Yes, if you lose the cats on an N/A car, you have to expect to lose some low end, because thats what backpressure somewhat helps with, but you will notice something more up top. Oh, and it just sounds badass...lol

 

I dont have the cats anymore and it sounds awesome. My car is n/a but didnt noticed and increase or decrease in power.
