Looking to buy a TSL Group N back box
 

As the title says, does anyone have a TSL Group N back box for sale? Thanks!

You'l do well to find one these days, haven't seen one for sale in a long time.

I have one! selling the midsection and backbox.

You have a pm

I had one of these on my FSTI. Found one for sale and modified it to fit, absolutely loved it!

From what I read this exhaust has a nice balance, good sound without being ott and a subtle look, I'm not a fan of massive exhaust tips. Currently I have the Prodrive exhaust, I think the TSL would make a small but noticeable difference.

Yep, it's a shame the no longer make these as I really like them too. Just a perfect sound. Mine had a de-resonated centre pipe too and I got no cabin drone at all, just a lovely low subaru burble that was good every day and sounded great without being far too loud on full chat. Love them!

If I can find a used one in good condition and fair price I will take it, otherwise I'll look at new exhaust, maybe Milltek, or choose one from Scoobyworld.

The Racebox is a reasonable alternative.

Have you tried it? I like the look as I prefer this smaller tip to the Prodrive one. But I'm afraid this RaceBox is too quiet, similar to Prodrive? I was also thinking about H&S, and maybe Ninja 2 even though I don't like the looks of it, but I want more sound.

This weekend I tried a Prodrive P1 GC8 backbox exhaust (small exhaust tip) on my 2005 STI and it sounded better than what I currently have, similar up until 3500 RPM but then it opened to an agressive "whoosh" sound up until the redline, very nice but still not exactly what I'm looking for.

No I haven't owned a racebox, but there are plenty of sound clips online on their site and youtube.

You'll find most systems on youtube so I would recommend trawling through that to find what you want.

I have a TSL GpN back box available. I need to pick it up from a friends place but can easy do that this week.

one on ebay too

Bump...

Mario’s search continues as mine isn’t a TSL. So sorry about that, Mario!

Spoke with him already but the price is a bit too high and also he doesn't want to ship outside UK, I don't know why.

Juggers please check pm

No problem Lewis!

What do you mean the price is high? That's bang on the right money for one of those systems second hand. I paid slightly more than that for mine second hand then cut it into bits to fit my FSTI. :)

I have a Racebox that hasn't done many miles in good condition I might be selling.

I've had both the Prodrive and TSL Grp N on my Classic, the TSL definitely sounds better without being offensive, I had a Cobra before and that was really loud. Think I paid about £100 delivered for the TSL.

They're a similar size both in silencer size

And tip size

And the TSL fitted

You can see why the Cobra was so much louder, the silencer is half the size

Thanks for the input, I don't understand how the TSL is noticeably louder than the Prodrive given that the silencer in both is the same size? Is it really much louder than the Prodrive? The Prodrive I currently have on my Newage has no sound at all.

That Cobra exhaust must be one of the loudest, I think they also make quieter models.

The prodrive silencer has smaller bore with small holes in all the way to the tip, thats possibly why.

It will be down to the internal design of the silencer, I expect the Prodrive would have been a compromise between noise and gas flow whereas most after market will be more concerned with the flow of gases rather than keeping noise levels down.

I managed to find a TSL Group N exhaust in a online store, they didn't know what exhaust that was, was announced as "aftermarket exhaust" and it was fitted previously to a RB320.

Paid 84 pounds + shipping which was a good price

Good deal, they sound great. Hoping my GeNome will sound similar...

I think the Genome sounds even better and louder?

That's the one I wanted but it is too expensive unfortunately, there are a couple of them on ebay.

Yeah, they arent cheap, I've had mine a while. I just used the rebuild budget as an excuse to spend money on what i've wanted forever. I hope its a little louder, somewhere between the TSL and a Nur Spec.

I've a Gp.A replica for when i'm wanting to wake the dead :lol1:

Looking at the size of the Genome silencer, it should be very loud.

If I can find one at a decent price it will be the next exhaust upgrade if the TSL isn't enough.

I took my Genome off and sold it in preference for my TSL system. The Genone has a restrictor at the entrance to the rear box to narrow the gas entry and make it travel faster through the box. As a result it sounds very loud indeed and very angry on full throttle, but ultimately restricted the gas too much and my car made far more power with the TSL system fitted and sounded better IMO.
