I bought mine from Nigel on skyline owners. He imported it, but by the time it arrived, he had sold his GTT. It is an unknown make with no markings on it and Nigel couldn't tell me where it came from

Still for only

Cheers for the replies on this one.

Cant help thinking that the TI is a bit overkill for my needs, its only from the cat back, which isnt very much on a Rex. If you have seen the cat you'd know why...its huge and weighs a ton (not literally).

Will try for a secondhand stainless one first and if not see what I can get.

Hopefully if I order it tomorrow it will come tue or wed and I can have it fitted before the meet.

The noisy airpump is driving me nuts lol

Yeh gareth titanuim sounds like a plan - I still recommend my HKS silent as it's easy to live with - loud when needed - silent when crusing (the motorway - not yarmouth sea front)

Good luck with the search Gareth :-D

I don't even know what make mine is as there are no markings on it :? ..........I think mine sounds similar to Bens on idle so it's probably a 'muffler' type one. I always wanted it changed to something like Stu's because his car shakes the ground when you are near it :twisted: but have grown to like it and am quite happy with it now 8) ...........if I want noise now I just take it above 5500rpm and let the screamer do the rest....best of both worlds

you sure about that ben, ive seen you on hellesdon cruiZers

:P

keeping it on topic: im sure there is a threshold where the quieter your exhaust is, the more restrictive it is? speaking personally, my 2.25" stainless exhaust is fairly quiet but does have an awesome raspy roar when my car goes on boost. im now at the stage where the exhaust system is restricting flow at the top end of the rev range.
generally speaking the larger bore the lower the exhaust tone.
have you thought about making your own? dunno if that applies to you, if youre any good with a welder. weve got an ally welder at work and im just researching* if its possible to weld titanium with the same kit!

*googling

Mate,

Will be interested to see how the HKS lasts - when I was researching mine I was warned that (for Super Dragers anyway) as only the can is stainless (the rest is aluminised mild steel) they don't stand up to the RX's high exhaust temps very well.

Sure it'll be ok til next year though

Cheers,
Alex

I was told it wasnt an official HKS but one similar to that type.

I read the same thing mate about proper HKS ones.

Must get to more meets next year to see a load of RX7s, just to compare bits.
