What is the best recommended exhaust for 20vt coupe?

Depends on what your requirements are:-
Noise
Performance
Looks
Longevity
Budget

Give us an idea on that lot and it can be narrowed down a little

be warned if you go for noise, I have a straight through system on mine with de-cat, there is a small back box and the decat has a silencer. The car sounds stunning but would be too much if it was my main car or doing long journeys as although not too loud on constant revs there is a little boom. ps am I right in thinking you are out Louth way?

I bought a cybox stainless cat back system from fleabay. Looks and sounds nice although wasnt a pefect fit TBH. The tail pipe sits slightly off-center in the bumper cut-out.

A little later i bought the cybox decat. Simple to fit and boosts power! Does get a little louder though!

If funds are unlimited I would say Blueflame is the way to go especially if decatted. If not I was pleasantly suprised with my cat-back Scorpion back-box. Lovely burble on idle and acceleration but nicely muted on the motorway when cruising...

supersprint -

Sound really nice around 4 to 5 thou RPM, and in the tunnels - at 70mph I can make the tunnel reverberate the whooooooooooorr noise - it makes me smile EVERY TIME - I give it the beans.

My little boy sits in the back seat Egging me on to "go faster Daddy" little chimper.

Supersprint exhausts aren't very good as they're made from mild steel and rust away in no time!

I couldn't recommend Longlife Exhausts enough. The one near me has always made custom exhausts for my car and at a very reasonable price. Comes with lifetime warranty as well and you can tell them exactly what you want.

+1 for longlife - Motormech do them, give them a shout for a chat!

I went for a full custom-made, from a well established garage. My words were: full flow, lowest noise possible.
Still very happy 6 years on!

I might sell my full 3" Longlife system soon, 5 stud flanged...

I have Powerflow on my three, and each of them makes a different noise! They are all fine so far...

Blueflame are supposed to be the mutts if your funds allow.

Im currently using a cybox with silenced de-cat, sounds awesome but a bit boomey inside, my previous coupe had a supersprint wirh straight through de-cat and the noise was the best ive heard from a non v8 (if that makes sense)
