what catback is the best for bpu?

[Guest speeddy]

I am now gonna buy me a new catback, so I wonder what catback is the best, that sounds the most, give the most horsepower and so on.

 

For now I am choosing between,

Hks ti carbon catback (3")

Blitz nür spec catback

 

If there is another catback that is better or sounds nicer just write it here.

 

Is a hks hiper 4" catback to big for BPU???

Blitz nurspec, cheap and cheerful, and very nice sound, correct size too, 4inch is not necessary for bpu and the HKS ti comes with a 3to a 4inch stepdown that you have to use if you dont have a 4inch downpipe,

 

You need a restrictor ring at bpu anyhow, so 3inch in the biggest size you should go for

 

Also the HKS ti is not a full titanium system, its only the resonator box which keeps the weight down, the main pipe is steel

[Guest speeddy]

ok, but if I can get the hks ti for the same price as blitz nür spec.

Wich one had you choosed?

Nur Spec has clearence issues, and is loud too but a nice loud. One exhaust I would consider that is even cheaper is Envy's copy of the RS*R.

 

The RS*R was a lovely exhaust and had a very nice sound, plus it fits better under the car and does not hang low like the Nur Spec, iirc the Envy copy is £100 cheaper too.

Pretty much any aftermarket cat back is perfectly good for BPU.

 

If you want noise:

 

Any Ti

Blitz NUR (clearance isn't so good)

RSR (best of all worlds IMO)

Boostlogic (the loudest of all exhausts but has clearance issues due to 4inch drainpipe)

You might want to consider getting one that has a removable baffle which you can fit if you want a peaceful long journey.
