Extractors on TM

Post by Wickmyster » Sat Mar 09, 2013 3:56 pm

Any thoughts on these Listing #: 569974872. It looks like where it goes 2 into one that having the top pipe go over the connecting pipe will cause a lot of disturbance :/

Don't think you'd gain any power with those over stock.

I went from an average set of Apexi 4-1 headers (no noticeable difference to stock) to a set of top quality Maruha 4-2-1 headers and the difference is absolute night and day.

If you have cracked/broken stock headers then it might be worth getting them but if you're after power you'll want a high quality set.

Aftermarket extractors

Don't waste your money mate
Stock exhaust manifolds work a treat.
I'm running 225hp through the standard exhaust manifold at the moment.
If they make a claim for power increases, ask if they'll give a money back guarantee if it doesn't make it on the dyno. Doubt they'll take you up on the offer.

Factory Headers

Post by Teamjelly » Sat Mar 09, 2013 10:37 pm

Yep, if you have a look under the heatshield, you'll see the factory setup is actually a very nice bit of kit,
I'd say most aftermarket setups would make little difference to overall flow. and probably crack after a while,

I have these headers on my car, when AL,S mufflers fitted them he said they look to be good quality. Did they give anymore power? Hard to say as I did the complete system at the same time and that did make a difrence (not masive but)

The car sounds great and they are very nice looking headers, but now I have a heat blanket and supercharger covering them :oops:

Hope that helps.

What size exhaust did you go before you supercharged? I wanna go 2.5 so I don't have to redo it when I turbo but I know it will be loud and probably lose power...

I went 2.5 and yes it is quite loud. Thinking I might have to put another resonator in before it gets complied.

Factory Exhaust

Post by Teamjelly » Sun Mar 10, 2013 3:38 pm

The stock exhaust is better than most people think
I'm still running the stock size, and making over 220hp
Might build a decent 2 1/4" setup later, but doubt it would give more than 5-10hp more if I was lucky.
With a turbo is may be a different story.

Yes one res and a jackson racing muffler, may need one more res to be certafiable. Ands lets face it.........we do a LOT of things to our car because it looks/sounds better than stadard and my exhayst system wins on both those reasons.

Yes it may only be 5-10hp better than standard but dam! it is wayyyyyyy cooler.

They look nice, probably built like shit.

As for exhaust, I'll definately need a 2nd reso, going for a centre exit straight system
