After fiddling around with exhausts for quite a while I have decided that I'll be replacing my cat back. For my rolling road tune I was running a hks centre section with 2.5" piping and some universal 2.5" back boxes. The power seemed ok but they were still holding the car back and also droned significantly between 2-3k.

 

I then updated my apexi system to use the new hks centre and full 2.5" piping. The sound was great if not a little too quiet but they are too restrictive for the tune I have now so they have to go.

 

What I want in a new exhaust:

 

3" performance system

No drone

Quad tips- square oval if possible

 

What I've looked at.

 

An ab flag power superior would be nearly perfect but not a viable option particularly for a swb ( I have seen the lab system on yahoo)

Velside- same as above but less keen on the twin large tips

B and B- seems a little over priced, the tips are perfect but the quality does not seem quite as good as others.

Sz- this is looking most likely as the quality looks spot on, performance is good and they offer quad tips.

Labree- seems similar but not quite as nice.

Ams- a copy of the sz and I'd rather pay the bit extra for the real deal.

Z1 pg- will be way too noisy.

Infinity- I know a few have these and they are well regarded- not sure how they would stack up in regards to performance and droning. Any pics and an idea of cost- having it fitted would be a nice bonus.

 

Anyone have personal experience with any of these ( funky si?) particularly with regards to noise- I don't mind a little loud but can't stand drone.

 

 

Anything I've missed?

I have an Infinity system on mine, Pete. Full 3" bore, custom-made X-pipe and the only silencers are the backboxes.

 

I like it. It's not super-loud and it's not as droney as I expected it to be either. It's blatantly a 3" system though, so you're not going to hear pins drop. It's a well made system although they went for a somewhat abstract design for the rear pipework which isn't actually symmetrical....

 

Mine cost £750 all in from the turbo elbows back last year. Rumour has it that their pricing is creeping up nowadays though...

For a swb? Any pics

 

Wouldn't say so Pete, I've a wanted ad for a SWB exhaust up since the middle of May:innocent::whistling::yes:

Bit of a bump on this.

 

After doing some more research on this I think I'll be going with the sz 3" with a resonated x pipe and quad round tips.

 

has anyone any experience with this setup?
