Today got a new exhaust system fitted, got the extractors aluminium coated and went from a 3.5inch single to twin 3.0 inch and Lukey Race series mufflers and x pipe. The pipes end at diff to keep it 3 inch all the way. A bit boomy at idle but a very deep note driving along...

Bonus all round, under 3000 haven't lost any driveability and I think this is due to the affect of the x pipe. Top end I have gained a heap of grunt - no dyno comparison - but going by the additional spin I'm getting through the gears, perhaps as much as 20-30HP gain.

Highly recommended.

It's my belief that any decent V8, especially a cleveland, gains a lot of benefit from a decent twin system.
What did you have before?

Soxx

Agreed, even twin 2.5" will work fine a big power Clevo.

What's that?..... Did I hear you say TQE power?

Don't the pipes have to end at the bumper? Thought it was illegal if they ended at the diff.

3in is a huge twin system!

Racer

I used several on my Cortina. 3 inch single, dual 2 1/4. dual 2 1/2 and found no measurable difference on the track when running street trim low 10's through the pipes.

I did however pick up 36 RWHP going 1 5/8 to 1 3/4 with the extractors.

STROKEXD

Racer some of my gains could be the extractor bore increase, I went 1 5/8 upto 1 7/8 with this new set-up.

Clevo yeah isn't everything that's fun illegal?

and here i was thinking i could get my exhaust sorted for under $900... :(

what do you guys think the going rate should be for a twin 2 1/4 or 2.5 inch system for a ZH Fairlane? I'm going to buy a set of 2nd hand extractors...

Soxx

Some of the gains could also be the type of mufflers used.
