AmSnow440 Posted June 17, 2011 Share Posted June 17, 2011 Bit of a weird situation here. I just bought a 2005 LGT that has an Equal Length Header on it, however I'm not too thrilled with how the car sounds at the moment (I want the boxer rumble back). I see a lot of posts that recommend a tune after any modification and rightfully so. I am going to install the GTSpec Unequal Length Header and Up Pipe. This is my first turbo car so I am going to be very cautious before I change anything on the engine. So my questions are: 1) Is a tune required to drive the car? 2) Is it ok to drive the car to the tuner without risking any damage? Here are the current mods done to the engine: - AMR One Piece Equal Length Header and Up Pipe - Invidia Catless Downpipe - Greddy EVO 2 CBE - DW 750cc injectors - Walbro 255 - Cobb Accessport V2 with custom tune - Stock Intercooler - Stock Turbo - Stock Intake - Stock BOV Link to comment Share on other sites More sharing options...
Spec B Posted June 17, 2011 Share Posted June 17, 2011 ^ Assuming you are already tuned for your mods (sans the new header), it is fine to drive to the tuner. In fact I would venture to say it is fine to drive without a tune. But unless you log, there is no way to tell if you are hurting your engine. IMO - I highly doubt you will hurt the engine by switching headers and not getting a tune. But then again, I am just some dude on the internet giving you advice! BTW...you should expect to lose power by switching to unequal length headers. generally speaking, equal length headers make more power than unequal. Actually, considering your mods (pretty much a stage 2) setup, you will likely not lose much power. The difference is much more noticeable in Stage 3+ cars. Good luck.

subiedad51 Posted June 18, 2011 Share Posted June 18, 2011 You may not lose much in the WHP area but you will lose Torque. I'm with you though I don't care for the sound of the ELH. Link to comment Share on other sites More sharing options...
1454 Posted June 18, 2011 Share Posted June 18, 2011 How much you want for the header? I don't care about the sound, and I was thinking about buying a elh, but I thought I might ask you and see how much you wanted. Link to comment Share on other sites More sharing options...

tbperry Posted June 20, 2011 Share Posted June 20, 2011 Alright this is an incredibly stupid question I am sure, but does my 05 LGT have ELH or what? It is stock, and I am very new to the world of mechanics, so i really don't know! Link to comment Share on other sites More sharing options...
subiedad51 Posted June 20, 2011 Share Posted June 20, 2011 LGT's come stock with Unequal - which gives the car the "boxer" rumble. Link to comment Share on other sites More sharing options...
tbperry Posted June 20, 2011 Share Posted June 20, 2011 Alrigh that is what I thought but after reading this thread I was lost. Thx for clearing it up Link to comment Share on other sites More sharing options...
AmSnow440 Posted June 20, 2011 Author Share Posted June 20, 2011 thanks for all the help. I'm gonna install the UEL Header and log to see how everything is, then see if a tune is required. Link to comment Share on other sites More sharing options...
