Newbie exhaust question

[pollpollard]

Hi guys, new on here and hopefully going to be getting a B7 RS4 Avant in the next couple of weeks.

I test drove a really nice Daytona example at Nick Johnson a couple of weeks ago, but unfortunately went on holiday and its now sold!

Anyhow, on the test drive I noticed how muted the exhaust was so I've been looking into options. My question is- do any of the non res h-pipes that replace the silencers fit the standard backbox? It looks like the Milltek and Surpersrpint ones only fit their respective full systems from what I can tell.

Any help would be great.

Thanks,
Andrew

1) FON
2) any decent exhaust manufacturer should be able to fabricate a H pipe - for example MRC offer this service to delete the centre resonators
3) welcome

The standard exhaust is one piece system from the cat back. This means that to change anything other than a complete cat back system you will need to cut up the original exhaust and hope they run a similar path or will need to fabricate a piece to join the 2 up. This is why no-one sells a back box but rather all sold as cat-back systems. Having said that Tubi only make a back box so this would need the OEM exhaust cut to mate or alternatively I bought a Milltek H-pipe and centre section and cut the Tubi to mate the 2 'half' systems together.
The H-pipes or X-pipes are not normally resonated. It is the bit further back (which Milltek call the centre section) that normally has a silencer or not (resonated or non-resonated).

There are lot of threads on here regarding exhaust options, and very recently too so have a lok through.
Amongst the options are full replacement, sports cats, gutting of pre-cats, deleting centre resonator or almost any combination there-of.

Disconnecting the exhaust flaps on the standard exhaust is a quick and free mod that improves the sound quite a bit! That could tie you over until you decide what exhaust set up to go. I'm in the same boat, best thing is to get to a meet and politely ask for some rides in some fellow forum member's cars to see what suits you best.
Good luck with finding one!

Thanks for the responses guys, I'll try to get along to a meet and listen to a few different set ups I guess.

The Revolution intake sounds good too... (I said I was done with modifying cars!)

Eager to get into one now
